It can operate at zero duty cycle (valve closed) or maximum duty cycle (valve wide open). However, fuel-efficient automobiles were environmentally and economically friendly and could cover more miles with far less fuel. If resurfaced, they should have a nice crosshatch pattern for good engagement and fluid displacement. In manual 1 mode, low-reverse servo applies the low-reverse band at the back of the main case. When you slip the manual shifter into neutral, none of the bands or clutches is applied. Harsh or Improper Shifting Without a valid speed signal from these sensors, the PCM will not be able to correctly control It does affect clearances. This shaft operates inside the outer stub shaft. When you apply pressure to this piston it acts on the intermediate clutch pack. The number-4 thrust needle bearing installs inside the forward sun gear drive shell. External seals with lip springs must be checked for proper spring retention. During installation, watch the seals and protect them from distortion. During this time, the coolant pressure went from 17 psi to 0. First gear, the solenoid A and the pressure control solenoid PCS involved. When they work properly, the 4R70W and 4R75W is a reliable transmission. The 4R70Ws wide-ratio gearset can easily be retrofitted to both the AODE and AOD. When we dropped the pan it was full of metal, as expected. They are controlled via two different hydraulic circuits. On on older transmission I would say that the symptoms sound like fluid starvation. In first gear in the drive range, the SS1 is on and the SS2 is off. Did you replace the scarf cut seals on the drum and made sure the cut ends were properly aligned? Make sure you have plenty of lube and smooth piston travel. The valve body is responsible for controlling the flow of fluid Fax: 330-434-3634, 2023 Gearstar Performance Transmissions. Bingo! Use plenty of lubrication, then drive the seal in. Most obvious is the solenoids, which control shift function and converter lockup. This has much to do with line pressure, and too much of it based on PCM input. If you have a malfunction in manual 1, check for power to the SS1 solenoid. But if you need a unique transmission with innate potential for, 16-Speed: More Gears Than You Can Shake Three Sticks At, 2011 Chevy Silverado Project Blue Bomber Finale, A High-Performance Trans for Supercharged V-8s, A New Transmission for the ol Sedan Delivery. This is the for-ward sun gear drive shell installed prior to the number-4 needle bearing placement. Lose the spring and you will have slip-yoke leakage. You also want to service the torque converter (not shown) with 2 quarts of transmission fluid, which helps prime the pump. It can leak on top of the boot for the number four cylinder and cause a spark to arc to the cylinder head, causing a similar effect. What gives? Ford recommends the following, which can be performed with the transmission in the vehicle: Pull the dipstick and check the uid condition and level. Erratic shifting One of the first symptoms of a bad or failing downshift solenoid is erratic shifting. The uid pressure is the same as second gear in drive range. Sometimes the MAF sensor causes transmission problems. Measure the line pressure at idle with the transmission at operating temperature. You can copy and paste this link to share: https://www.diyford.com/ford-aode4r70w-guide-calibration-building-troubleshooting/. I shifted down into 1st and it won't move, feels like it's in neutral. Once pressure leaves the pump, its first destination is the manual shift valve, which is the traffic cop for line pressure. To better tie the engine, vehicle, and transmission functions together, Ford went to an output shaft speed sensor and manual shift lever sensor, along with a multiplex electrical connector to simplify service. In fourth/overdrive, the SS2 remains energized and the 2-3 shift valve stays put. Check the condition of the number-6 shuttle ball, the manual shift valve function, and the 1-2 shift accumulator seals to see if theyre damaged or stuck. Legal/Privacy. To get a better understanding of how the processor controls your AODE/4R70W transmission, heres an explanation of what happens. Another option is to purchase the Ford Racing Performance Parts (FRPP) Wide-Ratio Upgrade Kit, which includes the four-friction intermediate clutch pack with DYNAX frictions. Begin with a plate and alternately stack clutch discs and plates. Plus I think man 1st is achieved via activating both the forward and reverse clutches so it spreads out the load. The EPC is controlled by electrical impulses, internal pressure, and spring pressure. Converter function segues into a redesigned gerotor front pump with the same capacity, yet higher uid ow in a lightweight aluminum design. The AOD has dual input shafts (inner and outer); the AODE/4R70W has one, which splines into the forward clutch. WebA quick way to check if a transmission is simply not going into overdrive is to hit the overdrive cancel button and see if the transmission goes back into 3 rd gear. The 2-3 shift accumulator drops into its cavity. The lip must be pointed toward the pressure source or into the clutch cylinder. Is there any tests I can do without pulling the trans first? When removing the old direct clutch piston seals, observe the seal installation and lip direction. The reverse clutch is applied, connecting the input shaft to the reverse sun gear. The same thing applies to automobiles with the AOD Electronic Controls in the 1990s. The fix was to replace the intake manifold. The needle bearing, also known as a Torrington bearing, reduces internal rolling and thrust friction. Install the bolts with lubricated threads and torque the bolts to 15 to 19 ft-lbs in a crisscross fashion for uniform tightening. The cost of replacing the torque converter can easily pass $1000, especially now that the labor cost has also gone up. The AOD efficiently replaced several older transmissions that Ford put out, including the C4, C5, and FMX. If you have no engine braking in manual 1, the problem isnt electronic. This cookie is set by GDPR Cookie Consent plugin. Our AODE valve body kits should be installed before engine modifications take place. Also, did you use seal protectors to install the pistons? Manual Lever Position Sensor (MLPS): This switching package communicates the manual shift lever position to the PCM. Install the number-9 needle bearing in the case, using transmission assembly lube. Although these transmissions have a great deal in common, they are also very different, with limits in interchangeability. Renew Subscription I would start by removing the valve body and inspecing it first. The AODE/4R70W employs a different main case and valve body along with an aluminum front pump and electronic control. We also use third-party cookies that help us analyze and understand how you use this website. Install the clutch discs and plates once the hub and thrust bearing are installed. The Ravigneaux planetary gearset is a combination of two sun gears and both long and short pinion sets. Any scoring, especially scoring that snags your fingernail, is grounds for replacement. A seal lip pointed the wrong way is a guaranteed leaker. Ford developed the AODE and 4R70W to achieve cohesive engine and transmission function in 1991. This allows for a pressure path to the direct clutch (engaged). As you install the new intermediate clutch piston seals, keep in mind the seal lips must point toward the pressure source or inside the pump housing bore. Cant get reverse gear? Yes, valve body was removed and Sonnax Sure Cure kit was installed. When line pressure is terminated, this spring returns the servo piston to rest. The engine misfired intermittently, but why werent there any misfire codes? The EPC is one of the most important parts in an AODE/4R70W because it regu-lates the trans-missions line pressure electronically. My 4R70W transmission is giving me trouble. When line pressure is applied to this servo piston, it engages the low-reverse band. Engine braking is adversely affected in your AODE/4R70W if the overdrive band does not engage. Change Your Address, Yes, I would like to receive emails from Gears Magazine. Torque the bolts in a strict pattern to prevent warping. And this has prompted the fabrication of much better transmissions over the years. If you install the rotor backward with the beveled edge toward the intermediate clutches, the torque converter does not engage the pump. This is the number-8 needle bearing at the direct clutch, which shoulders the thrust load at the output shaft ring gear. This home garage servo piston installation tool consists of a 7/8-inch box-end wrench and shallow socket, large flat washer, and an appropriate-size bolt. Privacy Policy. We went on the road test, and the unit worked great. Make sure it remains centered during installation. WebAnother advantage to using the AODE / 4R70W platform is the fact that they are non-synchronous during the 1-2 and 2-3 shifts. The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction. According to ASTG all your line pressures are fine. Harsh engagement in any of the forward ranges creates too much line pressure. And for this to happen successfully, the manufacturers had to sacrifice a handful of the speed and performance features that older models exhibited. I'm having a problem with my transmission in my 2003 Ford F-150 4x4 (4R70W). Ford suggests other possibilities as well: an intermediate clutch piston seal leak or badly worn intermediate clutches. Email info@mistertransmission.com. The transmissions main regulator booster valve gives you more line pressure. (You can unsubscribe anytime), ATRA Yet another issue could be the low-reverse one-way clutch. All Rights Reserved. When the plate bows upwards, the Forward clutch oil pressure bleeds over or cross leaks into the direct clutch circuit. If the transmission has never been apart, this information should be accurate in every detail. SHARE THIS ARTICLE:Please feel free to share this article on Facebook, in Forums, or with any Clubs you participate in. 178 subscribers. Privacy Statement - The seal grooves and seals must be hospital clean. The difference is the SS1 function. Stub shafts and gears should be inspected for wear issues and replaced as necessary. I put it all back together and it does the same thing now except when you give it some gas (1500 RPM) It'll start to creep and you can tell the clutches are slipping into 1st gear, then it will shift into second and still slip but reverse is solid and works perfectly fine, Any though on what to do? This TCI Automotive transmission overhaul kit has just about everything needed to complete an AODE/4R70W rebuild. Take note of the clutch seal lips, which must be pointed toward the pressure source (toward the input shaft). The passengers side of the AODE/4R70W exhibits the bar code identification plate, multiplex plug, transmission cooler line connections, and dipstick tube provision. Is the noise or vibration in rhythm with the engine, driveline, or wheels? Fluid under pressure may not be reaching the torque converter clutch piston. Apply uniform pressure to the piston while feeling for a smooth transition. Rock these assemblies back and forth until the forward clutch is completely seated in the reverse clutch drum. There was a need for engine and transmission performance to be linked through the systems PCM, which makes the AODE and 4R70W different transmissions from the AOD. Although the automatic overdrive transmission was relatively new, it still bore several features of old designs. The drivers side has the manual shift linkage. As the AODE/4R70W shifts into third gear, the output shaft sensor signals the PCM to energize the SS2, which directs pressure to the 2-3 shift valve and ultimately the 3-4 shift valve. Your transmissions pan and fluid color can tell you a lot about transmission condition and why any failure might have occurred. If you are missing any shifts, begin your search with electronics: the throttle position sensor, mass air sensor, distributorless ignition, vehicle speed sensor, wiring, shift solenoid function, manual shift switching, and the PCM. What Are the Different Types of Transmission Fluids? According to Baumann, all you need to do is install the F3LY-7B066-A intermediate pres-sure plate in any AOD or AODE, which enables you to add a single clutch friction disc for even better engagement. Inspect the reverse clutch Belleville return spring for cracks and distortion prior to installation. Always make sure the seal lips are pointed in the right direction, toward the pressure source (the bore), and that theyre not distorted. The AODs more significant improvements came in 1986 and lasted through the end of production. 1996-2004 Mustang 4.6L 2V 4R70W Transmission Gear Ratios. Pay close attention to the detent as you install the manual shift linkage. Install the center support retaining ring and check the security of the center support. Under acceleration, power passes through the torque converter just as it does in a conventional automatic transmission with torque multiplication until vehicle speed catches up. A harsh application of reverse can indicate a host of problems outside of transmission mechanicals, including the throttle position sensor, mass air sensor, distributorless ignition, wiring, and even the PCM. But when we checked the coolant for exhaust gases, there wasnt any. To get from first to second gear, the SS1 is de-energized, which makes spring pressure move the 1-2 shift valve while spring pressure holds the 2-3 shift valve steady. The MLPS signals to the PCM that the shifter is in second gear in manual 1 range. AODE units through 1995 are standard ratio with 2.40:1/1.47:1 gearsets, except those installed behind the 4.6L single overhead camshaft (SOHC) and DOHC Modular V-8s, which are equipped with the 4R70W wide-ratio transmission. It could also be a misfire. The case size is the same as the AOD. In other words, are the two pump halves securely tightened? Members Webafter it warms up at start up all night 1st gear has a problem engaging then after a minute it goes and there is no problem until i turn it off and after turning it off only for a long while like over night it does it again 8 people found this helpful. With that, Irvin reassembled the transmission. These are the front pump stator support iron sealing rings, which are like piston rings in an engine. The twin solenoids are shift solenoids that are on/off only with either each on or both on, depending on the shift timing. The direct clutch should be fitted with new steels and frictions. Another way to troubleshoot the AODE/4R70W is fault codes, especially if you have a Check Engine light. There is only one way to install the front pump. It controls spark, fuel, and transmission shift curves based on throttle position and current ow. Use plenty of lubrication on the center support bushing. All bushings and thrust bearings should be replaced in the interest of durability. Pressure against the seal lip is self-sealing and fail-safe. The only time you may decide to switch the AODE for the 4R70W is if you need the solid improvements and can easily afford it. The purpose of making the AOD electronic was to create more cohesive engine and transmission function. The AODE/4R70W is a 4-speed, rear-drive automatic overdrive with electronic control, hence the AODE designation. When there is no power, the shift valves are closed. Install a new overdrive band and anchor it to the pin. The direct drum was burnt, as well. Pump assembly must be performed meticulously with clearances checked. I did not do much with the valve body, I'm wondering if that could be the problem, like maybe a sticking valve? Install the low-reverse band servo piston return spring. Gather all parts on a hospital-clean work surface and organize them into groups of unassembled subassemblies that make up the various components. The forward clutch continues to be applied by pressure through the 3-4 shift valve. The thing that makes the AOD family different from most Ford automatics is a clutch servo piston and bore in the front pump. Install the number-7 C-clip. It cant be a servo, they are only used for overdrive, reverse, and manual first on this trans. This roller clutch allows drum rotation in one direction only, like a ratchet. Use assembly lube as an adhesive to install the thrust washer. Gears Magazine Top. This cookie is set by GDPR Cookie Consent plugin. Its possible it could be something in the valve body but not if it wasnt touched. The cookies is used to store the user consent for the cookies in the category "Necessary". They should rattle when you shake the clutch and shaft assembly. The MCCC again gets pulses from the PCM tied to driving conditions. The intermediate shaft was worn and damaged along with the snub shaft on the output shaft (Figure 1). Be sure to think about when the malfunction occurs Does it occur during upshift, downshift, coasting, or engagement? When in drive, first gear slips but when in manual first gear, no slippage. There it was a misfire. JavaScript is disabled. That's my plan of attack, thanks for the help. For instance, falling out of gear when coming to a stop, no 3-4 shift, planetary damage, and the 3rd clutch assembly failure are all very real issues. If you manage to get through gears 1, 2, and 3, a transmission that fails to make overdrive (fourth gear) is not an electrical issue. Theyre either on or off or on/off in a duty-cycle (pulse) pattern. Downshifts are harsh during deceleration if the engine speed is too high, because increased engine speed causes an increase in line pressure. What is the engine idle speed? Note the proper installation and how the rollers are located (arrows). Keep in mind, Reverse does not use a solenoid 'like' the forward gears. The plates should have a good crosshatch pattern. Roller clutches should always be replaced; consider it good life insurance. Rollers become pitted, and this isnt always visible. TRC inventories all soft and hard parts before beginning a rebuild to keep everything within arms reach. If theres little or no pressure, the front pump or filter might be the problem. Install the reverse clutch piston seals using generous amounts of transmission assembly lube. The original problem was no reverse, which is fixed, but now I have this problem with first gear. Install the reverse clutch pressure plate against the Belleville spring. Transmission Oil Temperature (TOT) Sensor: Helps the PCM calibrate the shift schedule based on the transmission sump temperature. This installs exactly as you see here with a cover and C-clip. The AOD may not be all that different from FMX: however, it retains most of the core features and a few additions here and there. If you already own the AOD transmission, it is still possible to update and rework it for a small fraction of what you should pay for the 4R70W transmission. When they are lined up, torque bolts to 62 to 88 in/lbs (not ft-lbs). Cages become damaged and at times this is even harder to see. Make sure the C-clip is secure before moving on. Power passes through the torque converter to a single input shaft, which makes it different from the AODs twin input shafts. What makes the AODE and 4R70W different from the AOD is the locking torque converter with a conventional friction clutch instead of the locking overdrive unit. The forward clutch friction and steel clearances should be .050 to .089 inch. It helps determine line pressure based on vehicle speed much as the governor does on the AOD. There are four grooves but just three sealing rings. Archive - This O-ring seal should be lubricated with transmission assembly lube and rolled on square. The planet carrier splines inside the ring gear with gentle back-and-forth twisting to achieve proper engagement. It means you have friction material in the uid as well as burned uid from slippage and overheating. The manual shift linkage and manual valve line up like this. Give these rings and grooves abundant lubrication. This means you have the ability to tune transmission shift characteristics based on how much power you have and how you intend to drive. The seal lip should be pointed toward the pressure source (inside the bore). Ring thicknesses are .060 to .064, .074 to .078, .086 to .092, and .102 to .106 inch. By 1980, Ford created the 4-speed automatic overdrive transmission (AOD). The forward drum as far as I can tell looks to be in perfect shape. How did the forward clutch drum look? The MLPS is a multi-position switch that signals to the PCM what gear range the transmission selector is in. There are two bands, two one-way clutches, and four friction clutches used to lock and drive the gearsets. This transmission has lower gear ratios in first and second gears, which brings about improved When the solenoids are energized, the valves are open. Check this pressure plate for freedom of movement before installing the pump. Do not take shortcuts. These sealing rings must be well lubricated for pump installation. Account. Also install the input shaft sealing rings at this time. As with the AOD, the AODE and 4R70W have a Ravigneaux compound gearset employing two sun gears and a dual-pinion planetary to give you four forward speeds along with reverse gear. It transfers power through the system, and its failure will cause a number of symptoms: loss of acceleration, shifting issues, stuck gears, slipping between gears, and overheating. Any seal bind is a guaranteed leak. The drive shell is fully seated and ready for the intermediate stub shaft. Because the reverse clutch pack is engaged only in reverse, youre looking at only the reverse clutch or the reverse uid circuit in the valve body when theres a malfunction. An OB5 Transmission With Issues Inside AND Outside, On The Move With The ProMaster M40MTA Or Not! By clicking Accept, you consent to the use of ALL the cookies. This allows for proper seating and prevents warping. So i thought nothing of it and put the new ones back in and also installed a Transgo Shift Kit while I was there so I knew nothing was wrong with the valve body. You also have the option to opt-out of these cookies. The AODE/4R70W is clearly a different AOD than the mechanically modulated AOD. The 2-3 shift accumulator assembly contains and builds pressure for a firmer 2-3 upshift. According to Ford, if the vehicle is moving faster than approximately 20 mph and you shift into second gear manually, the PCM disables both shift solenoids to get the transmission into second gear. Is it a noise or vibration? Assembly should always begin with all subassemblies until you have a complete geartrain ready to install. Lubricate the bolt threads and check the bolt travel. But opting out of some of these cookies may affect your browsing experience. Did the problem arise after transmission service or part replacement? The cookie is used to store the user consent for the cookies in the category "Analytics". Advertising - Before getting into the workings of the AODE and 4R70W, it is important to understand their structure. In second gear in manual range, both the SS1 and SS2 are off. When you build, use new Torringtons if possible. Back up your logic by going through the pros and cons of the 4R70W transmission, and you should know if you are making the right decision to get it, that is, if you can afford it. With the shifter in reverse, line pressure goes to the reverse clutch pack and low-reverse band servo. Never reuse old bearings or seals. The direct clutch hub goes up against the number-7 thrust bearing. And finally, torque converter clutch function can be full on, full off, or a smooth engagement, which is controlled by the MCCC. Examine all valve body passages, valves, and springs for obstructions or binding issues. Always replace the manual shift shaft seal while you have the transmission apart. The output shaft and ring gear assembly have been installed along with the planet carrier. Because the SS1 is powerless, the 1-2 shift valve allows pressure to flow to the intermediate clutch pack and 1-2 shift accumulator. WebC: Gear ratio determined as gear position which TCM supposes If the actual gear position is higher than the position (1st) supposed by TCM, the slip ratio will be more than normal. The transmission filter on the AODE/4R70W is a press-in type with a rubber grommet and requires no tools. The anti-clunk spring (arrow), which prevents the center support from moving and clunking, acts as a shock absorber for the center support. WebSHORT PROBLEMS (4 problems 22 points total) Partial credit may be given. Bucko133. Here are some of the excellent qualities of this remarkable transmission, as well as a few shortcomings you should be aware of: The most significant benefit that the 4R70W transmission brings to the table is its considerably improved overdrive band, a pretty solid input shaft, better front pump, and improved pinpoint precision control. These cookies ensure basic functionalities and security features of the website, anonymously. WebThe 4R70W/4R75W transmission is susceptible to issues that include: loss of forward gears, intermediate clutch failure, loss of second gear, delayed reverse or shudder in reverse, To put the AODE/4R70W into gear, your foot must be on the brake pedal, which makes it mechanically possible to slip the selector into gear. A lone sealing ring (PN 87054-S96) goes in the top groove. This cookie is set by GDPR Cookie Consent plugin. It is recommended that you lube the thrust bearing with transmission assembly lube for a good wet start-up. Next, we suspected the intake manifold. Parts: 330-434-0104 Your Fords EEC-IV and EEC-V processor conducts the orchestra that is your AODE/4R70Ws hydraulics. I did replace scarf cut seals and made sure they went in properly. However, for the sake of longevity, replace yours. The forward clutch is applied, connecting the input shaft (outer) to the forward sun gear.
