Did the problem arise after transmission service or part replacement? The SS1 stays on, keeping the transmission in first gear. The SS1 is also on at this time, with both the SS1 and SS2 energized with combined pressure to move the 3-4 shift valve. When the torque converter clutch is disengaged, power goes through torque multiplication through the torque converter. Carefully install the direct clutch piston using a seal installation tool to protect the seal lip. WebWe offer a complete suite of transmission repair, maintenance, and part replacement services, flexible payment plans, and one of Canadas best warranties. Make sure you wipe it off and put it back in for a more accurate reading. Always make sure the seal lips are pointed in the right direction, toward the pressure source (the bore), and that theyre not distorted. Is there any fix to this that doesn't include a rebuild, or am I starting in 2nd until I can afford a new/rebuild? Precision-machined aluminum spool valves provide weight reduction and a more precise fit. Cart All seals must be generously lubricated and installed properly for effective sealing. Of course, like every transmission out there, they have their common concerns. Parts: 330-434-0104 These cookies will be stored in your browser only with your consent. Cookie Policy - The forward clutch friction and steel clearances should be .050 to .089 inch. There should be nine springs in serviceable condition free of distortion. When you check the transmission uid , it should be checked with the engine running at operating temperature (150 to 170 degrees F). Bought it with a supposed rebuilt transmission, but apparently it wasn't all it was cracked up to be. Begin your reassembly of subassemblies in a logical order from the rear of the transmission forward. Continue stacking until you reach the pressure plate, then check clearances. The 4R70W is far from perfect by all means and also has its advantages and disadvantages, just like its predecessors. If the downshift solenoid has any issues, it may cause the vehicle to behave erratically when downshifting. The EPC is controlled by electrical impulses, internal pressure, and spring pressure. It was not on the floor, so we figured the head gaskets were to blame. Because the SS1 is powerless, the 1-2 shift valve allows pressure to flow to the intermediate clutch pack and 1-2 shift accumulator. Recently, I did some research at my friend Rodgers shop in Miami, FL. The MCCC is off (on the torque converter, no lockup). Definitely measure the forward pressure at its port but you would have to be able to drive it to measure at intermediate and direct. 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 1-2 shift valve remains as is. Top. 132 N. Howard St, Akron, OH 44308 The plastic intake manifold warped between cylinders one and two, and six and seven, allowing coolant into the cylinders, which causes the misfire. Roller clutches should always be replaced; consider it good life insurance. The same thing applies to automobiles with the AOD Electronic Controls in the 1990s. As the 4R70W evolved to the 4R75W, an input shaft sensor was added. I shifted down into 1st and it won't move, feels like it's in neutral. Fax: 330-434-3634, 2023 Gearstar Performance Transmissions. 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. Ford AODE/4R70W Guide: Calibration, Building, Troubleshooting Ford Forum is a community to discuss all things Ford. Shop Finder The cost of replacing the torque converter can easily pass $1000, especially now that the labor cost has also gone up. Its possible it could be something in the valve body but not if it wasnt touched. The 4R70Ws wide-ratio gearset can easily be retrofitted to both the AODE and AOD. Double-check the security of the band at the servo and anchor pins. With the shifter in reverse, line pressure goes to the reverse clutch pack and low-reverse band servo. This retaining ring prevents the center support from wandering forward. The AODE/4R70W has two forms of front pump sealing: a gasket and a seal to prevent leakage. 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. Manage Preferences - Air pressure should be applied to serve as a valve function check. The AODE/4R70W direct clutch is a stronger stamped steel with more clutch surface area for durability and power transfer. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. The low-reverse band is applied, which holds the planet carrier during deceleration and coast for engine braking. 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. The MCCC engages and disengages the torque converter clutch. When we dropped the pan it was full of metal, as expected. The AODE/ 4R70W differs from the AOD in input. The AOD efficiently replaced several older transmissions that Ford put out, including the C4, C5, and FMX. 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. Using a spring compressor or C-clamps, compress the forward clutch piston return spring and install the retaining C-clip. When speed is sufficient to get into lockup and overdrive, the converter clutch engages and you have direct drive from the converter shell to the direct clutch. The pressure regulator valve bore in the valve body was worn out. Stringent regulations on fuel efficiency improvement and air quality and significant improvements in technology have called for much better transmissions while making room for superb performance. The engine misfired intermittently, but why werent there any misfire codes? They should rattle when you shake the clutch and shaft assembly. Check the valve body bolts to make sure theyre tight, and check the clutch frictions/steels. Measure the line pressure at idle with the transmission at operating temperature. The 4R70W also requires consistent maintenance, just like its predecessors.This way, you will have an incredibly powerful transmission. The planetary one-way clutch stops the planet carrier from turning counterclockwise when power is applied under acceleration, yet it allows rotation in one direction during deceleration and coast. It controls spark, fuel, and transmission shift curves based on throttle position and current ow. Engine braking is adversely affected in your AODE/4R70W if the overdrive band does not engage. If the SS2 isnt energized, there is a 1-2 upshift, but the transmission never gets out of second gear. Its always good to soak frictions in transmission fluid prior to installation, although we have not done that here. Torque the gasket bolts to 107 to 132 in-lbs, not ft-lbs. In second gear in drive range, both the SS1 and SS2 are off. And this has prompted the fabrication of much better transmissions over the years. 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. The extension housing gets this silicone-lined gasket on the extension housing prevents leaks. 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. 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. There are two bands, two one-way clutches, and four friction clutches used to lock and drive the gearsets. It was The intermediate clutch is also applied at this time, but does not transfer power as a result of the freewheeling intermediate one-way clutch. The planets one-way clutch overruns. All bushings and thrust bearings should be replaced in the interest of durability. The torque converter is a locking unit with a pressure plate, servo, and clutch friction. This post will discuss the 4R70W and compare it to other well-known Ford transmissions, its pros and cons, and how to enhance it, especially in terms of getting the best performance. The MCCC is off. Next, we suspected the intake manifold. Because these springs are attached to the pressure plate, they should all be present and in serviceable condition. If you point the seal lip toward the intermediate clutches, you will have an internal hydraulic leak and no intermediate clutch function. The uid condition is your first indication of transmission health. It can pop out if it is not completely seated.

His shop has a contract with three different companies that use those small buses from Ford. I just jumped into it last time without knowing what it was and it bit me. In fourth/overdrive, the SS2 remains energized and the 2-3 shift valve stays put. The Fora platform includes forum software by XenForo. Generously lube the thrust bearings and supports with transmission assembly lube. WebFord 4R70W/4R75W Transmission Information. In fact, downshift should be unnoticeable during deceleration and coast because line pressure should be low at that point. Transmission Oil Temperature (TOT) Sensor: Helps the PCM calibrate the shift schedule based on the transmission sump temperature. Also install the input shaft sealing rings at this time. Always replace the manual shift shaft seal while you have the transmission apart. Be sure you know the proper location for these sealing rings and seals. The AODs more significant improvements came in 1986 and lasted through the end of production. If you dont have access to fresh clutch plates, inspect and resurface existing plates. When you purchase through links on our site, we may earn an affiliate commission, which supports our community. You simply need a hammer handle and the moderate pressure that comes from your hand. The intermediate clutch discs and plates stack up like this. What Are the Different Types of Transmission Fluids? Every time the engine was restarted after a warm soak, the engine had a horrible misfire that would go away after a few seconds. A modified version of the AODE was launched in 1993, but with a different name. 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. Further enhancements come from the Baumannator Electronic Transmission Control System, which enables you to fine-tune shift performance. Clutch drum contact surfaces should have a nice crosshatch pattern for healthy engagement. This is the natural color version (.085 to .089 inch). Use plenty of lubrication, then drive the seal in. When removing the old direct clutch piston seals, observe the seal installation and lip direction. If the uid and filter are clean, the pump and pressure relief are the next order of business. Reproduction in whole or in part without permission is prohibited. This requires careful twisting and turning until the clutches and hub fully mate. It does what the governor did hydraulically. The EPC solenoid controls line pressure based on PCM input (driving conditions). Four iron sealing rings install on the output shaft. If clutch and servo are an issue then internal work is needed. 178 subscribers. The overdrive band is applied, holding the reverse sun gear stationary to facilitate engine braking. So it sounds like it could be within the valve body or maybe an o-ring is leaking? Does it happen in one gear range or in all? 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. No 1st Gear Been having issues with the truck accelerating slowly. Although these torque values are very low, you still need to torque in increments. When they work properly, the 4R70W and 4R75W is a reliable transmission. Check the vehicle (visually inspect the vehicle). 2. Sales & Info: 330-434-5216 The lip must be pointed toward the pressure source or into the clutch cylinder. Install a new overdrive band and anchor it to the pin. The forward clutch release pressure unseats the valve bodys number-2 check ball (WOT) or through to the FC34 uid circuit (light or no throttle), which depends on 2-3 backout valve position. The vehicle in question was a 2014 Ford Econoline E-250 bus. Privacy Policy. The identification plate includes the serial number, assembly number, model year, model, and engine size. 2.7K views 3 years ago.

Then re-torque them for a final check. JavaScript is disabled. When they work properly, the 4R70W and 4R75W is a reliable transmission. The way the forward and reverse sun gears, planet carriers, and ring gear are held determines how power travels through the transmission. Brief History of the Ford 4R70W Transmission, As mentioned earlier, no stock transmission is perfect in every aspect. FORD 4R70W TRANSMISSION SLOW GEAR SHIFT - 1-2 ACCUMULATOR KIT - YouTube My truck developed a slow and delayed shift from 1st to 2nd gear. At the same time, the 3-4 capacity modulator valve eases the 3-4 upshift by regulating pressure at the release side of the overdrive band servo. Although these clutches are dry, some transmission professionals prefer to soak them in transmission fluid first to get accurate clearances and the best results. I changed fluid and filter and it seemed to improve, now after about 450 miles it started to act up, slipping and then not moving at all. Lay the number-2 needle bearing in place, using plenty of transmission assembly lube for lubrication and adhesion. Terms of Service - Both transmissions are significantly improved versions of the first 4-speed AOD (automatic overdrive transmission) that Ford created and provided as a much-needed solution to fuel efficiency problems created in the United States by the oil embargo of the 1970s. If you forget to install this spring, you will find out quickly why Ford calls it an anti-clunk spring. 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. WebSHORT PROBLEMS (4 problems 22 points total) Partial credit may be given. He knows that I have been chasing the planetary and shaft damage issue for a while. Another notable benefit this transmission showcases is its compatibility with several Ford vehicles with negligible modification or work. The direct clutch is applied, tying the input shaft to the planet carrier to the smaller inside input shaft (stub shaft). Do a leak check with compressed air. While this might not be a bad idea, it could lead to a clearance issue. 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. Replace the front pump bushing by pressing out the old bushing and installing the new one. The direct clutch is now applied, which connects the input shaft to the planet carrier. Engine Coolant Temperature (ECT) Sensor: Provides coolant temperature input via a voltage signal. During this time, the coolant pressure went from 17 psi to 0. Begin with the simplest, most commonsense issues. Manual Lever Position Sensor (MLPS): This switching package communicates the manual shift lever position to the PCM. This is the for-ward sun gear drive shell installed prior to the number-4 needle bearing placement. The drivers side has the manual shift linkage. Installing them wet gives them a good start against freshly resurfaced clutch drums. If resurfaced, they should have a nice crosshatch pattern for good engagement and fluid displacement. The other four thickness options are green (.050 to .054 inch), yellow (.068 to .072 inch), red (.102 to .106 inch), and blue (.119 to .123 inch). Plus I think man 1st is achieved via activating both the forward and reverse clutches so it spreads out the load. It may also remotely be a The reverse clutch is applied, connecting the input shaft to the reverse sun gear. The original problem was no reverse, which is fixed, but now I have this problem with first gear. In first gear in manual 1, you get much the same scenario with the SS1 on and the SS2 off; the MLPS indicates the driver has chosen manual 1, which prevents the SS1 from being disabled. Pick-up not installed correctly,clogged filter,low fluid. 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. The torque converters turbine drives the input shaft. There are other issues with these valve bodies you should look for, like flooding solenoids, shift valve spring weakening, and leaking plugs. There are four grooves but just three sealing rings. Transmission Control Module: Buyers Guide for Classic Cars. Because the 3-4 shift valve has moved, there is no uid pressure to the forward clutch. The extension housing received a new bushing. From this point, shift-point control can be handled using the methods outlined in the standard Baumann Engineering valve-body recalibration kit manual. Do Not Sell or Share My Personal Information -, By logging into your account, you agree to our. When the solenoids are energized, the valves are open. Others install them wet. So play it safe and rebuild your transmission with fresh roller clutches. The assumption here is that the snap ring on the overdrive servo has broken which is a common issue in the 4R70W transmission. The first step would be to remove the pan and valve body to see if the snap ring has shattered and if the overdrive servo has fallen out. Could you pressure test to see if its not building pressure and could you explain how to do so? My 1st guess is a rolled or cut lip seal. All of these items are checked by dropping the valve body and visually inspecting them. Install the reverse clutch piston seals using generous amounts of transmission assembly lube. Apply uniform pressure to the piston while feeling for a smooth transition. Electronic Pressure Control (EPC) Solenoid: Your AODE/4R70Ws pace-maker. The seal lip should be pointed toward the pressure source (inside the bore). The direct drum was burnt, as well. If you have no engine braking in manual 1, the problem isnt electronic. The lip needs to face the fluid. If there are no serious signs of rotor or cavity wear, the pump can be returned to service. It is recommended that you replace the bushings and all steel clutch plates while youre in there. If you have a malfunction in manual 1, check for power to the SS1 solenoid.

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. Is the torque converter doing its job? Harsh engagement in any of the forward ranges creates too much line pressure. 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. Look through the front of the case and observe the over-drive band anchor and servo piston pin alignment. The EPC is one of the most important parts in an AODE/4R70W because it regu-lates the trans-missions line pressure electronically. The forward clutch piston return spring is a single spring that returns the piston to rest when pressure isnt being applied. However, for the sake of longevity, replace yours. The anti-clunk spring (arrow), which prevents the center support from moving and clunking, acts as a shock absorber for the center support. The low-reverse band is applied, which holds the planet carrier. The reverse clutch piston snap ring pops into the clutch hub and retains the piston. If you were noticing less If you liked this article you will LOVE the full book. Check out our discussions on the Ford Escape, Mustang, Edge, F-150, Raptor, Explorer, Focus, Fusion, Fiesta and more! It is recommended that you lube the thrust bearing with transmission assembly lube for a good wet start-up. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. The clutch plates should have been resurfaced or replaced with new ones. Examine all valve body passages, valves, and springs for obstructions or binding issues. When in drive, first gear slips but when in manual first gear, no slippage. A good rule to remember is that AODEs are standard ratio with 2.40:1/1.47:1 gearsets, while the AOD and 4R70W are wide ratio with 2.84:1/1.55:1 gearsets. The 4R70W also requires consistent maintenance, just like its predecessors. The harness protects the wiring. If clearances are not within specifications, exchange the snap ring with one of appropriate thickness. Review service information such as Technical Service Bulletins (TSB). 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. , replace yours explain how to do so smooth transition properly, the coolant went!
