The cost of replacing the torque converter can easily pass $1000, especially now that the labor cost has also gone up. As you mate clutch assemblies, ensure complete mating and seating before loading each assembly into the case. Install the intermediate clutch servo piston in the front pump. The 4R70W differs from the AODE in terms of gear ratios. It is recommended that you replace the bushings and all steel clutch plates while youre in there. Give these rings and grooves abundant lubrication. Pressure all by itself doesnt move the 3-4 upshift valve. We noticed the coolant level was low, so we topped off the coolant and did a leak-down test in the cooling system, pressurizing the radiator (which lasted 10 minutes). Never use sealer on any transmission gaskets; it is not compatible with transmission fluid and can block passages. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction. Ford Forum is a community to discuss all things Ford. Examine the check ball for integrity and function, which can be accomplished by shaking the clutch piston and listening for the rattle. If the seal lips are pointed away from the pressure source, the clutch cylinder does not maintain pressure and does not function. Do Not Sell or Share My Personal Information.

Pick-up not installed correctly,clogged filter,low fluid. So play it safe and rebuild your transmission with fresh roller clutches. The forward clutch friction and steel clearances should be .050 to .089 inch. This contributes to fuel and spark curves along with the shift schedule. Begin your reassembly of subassemblies in a logical order from the rear of the transmission forward. Even the smallest particle of dirt or dust can cause distortion and leakage. Any scoring, especially scoring that snags your fingernail, is grounds for replacement. Review service information such as Technical Service Bulletins (TSB). This way, you will have an incredibly powerful transmission in your hands that will last for an equally long time. Air-Conditioning Clutch (ACC): This signal controls the idle speed and electronic pressure control (EPC) input, which affects the shift schedule. The MCCC gets pulsing signals from the PCM. A switch to the wide-ratio gearset increases the 1-2 shift-point by 18.3 percent (multiply 4,800 rpm by 1.183 to obtain a new shift-point of about 5,680 rpm). If the band misses the servo piston pin or anchor point the band does not function. Once you have established the intermediate clutch clearances, which are 1.634 to 1.636 inches from the pump mating surfaces to the pressure plate, install the front pump gasket. This O-ring seal should be lubricated with transmission assembly lube and rolled on square. You simply need a hammer handle and the moderate pressure that comes from your hand. Use plenty of lubrication on the center support bushing. The bolt torque is 62 to 88 in-lbs. 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. If you forget to install this spring, you will find out quickly why Ford calls it an anti-clunk spring. The seal grooves and seals must be hospital clean. In second gear in manual range, both the SS1 and SS2 are off. Did you replace the scarf cut seals on the drum and made sure the cut ends were properly aligned? Contact Us - Yes, valve body was removed and Sonnax Sure Cure kit was installed. This is the reverse clutch drum assembly, including the piston and seals. The main control pilot bolts receive 140 to 160 in-lbs (not ft-lbs). Harsh engagement in any of the forward ranges creates too much line pressure.

Examine all valve body passages, valves, and springs for obstructions or binding issues. The needle bearing, also known as a Torrington bearing, reduces internal rolling and thrust friction. Make sure you have plenty of lube and smooth piston travel. If there are no serious signs of rotor or cavity wear, the pump can be returned to service. Have you checked the fluid for proper level and burning This is the 1-2 shift accumulator, which also stores pressure for a more solid upshift. Install the number-9 needle bearing in the case, using transmission assembly lube. GearStar Performance Transmission This is the direct clutch, steels, and thrust/needle bearings. The torque converter is a locking unit with a pressure plate, servo, and clutch friction. This shaft operates inside the outer stub shaft. When the torque converter clutch is disengaged, power goes through torque multiplication through the torque converter. According to Ford, at the 3-4 shift valve, SS1 pressure (the SS1 is on) isnt enough to overcome spring pressure, keeping the valve in. If Although your AODE/4R70W project may not appear to need it, its a good idea to replace certain hard parts such as the Belleville clutch piston return spring. Mark helpful 40 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. We went on the road test, and the unit worked great. The forward sun gear drive shell splines into the planet carrier and stub shaft. Begin your troubleshooting with electronics, then mechanicals. This is the natural color version (.085 to .089 inch). Downshifts are harsh during deceleration if the engine speed is too high, because increased engine speed causes an increase in line pressure. Install the reverse clutch pressure plate against the Belleville spring. Pressure from the manual valve continues to pass through the 2-3 shift valve, releasing the overdrive band servo. Sometimes the MAF sensor causes transmission problems. The low-reverse band is applied, which holds the planet carrier. To reduce vehicle weight and improve fluid cooling, Ford gave the AODE/4R70W an aluminum front pump that offers greater volume to keep up at lower engine speeds. 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. What Are the Different Types of Transmission Fluids? Make sure all holes line up, then mate and secure the pump halves. Troubleshooting the AODE/ 4R70W begins with ascertaining the problem. Torque the gasket bolts to 107 to 132 in-lbs, not ft-lbs. The gear ratios of the 4R70W transmission are: First gear: 2.84 Second gear: 1.55 Third gear: 1:1 Fourth gear: 0.70 The respective gear ratios of the AOD are: 1st You also want to service the torque converter (not shown) with 2 quarts of transmission fluid, which helps prime the pump.

Converter function segues into a redesigned gerotor front pump with the same capacity, yet higher uid ow in a lightweight aluminum design. Band assemblies, such as clutches, can be installed wet or dry. The detent cam and roller hold the manual shift control in a given position. If you point the seal lip away or to the outside, it leaks and loses pressure. Although the automatic overdrive transmission was relatively new, it still bore several features of old designs. Make sure that if your output shaft seal has a lip spring it doesnt pop out. Profile Ignition Pickup (PIP): A cylinder identification signal for the electronic distributorless ignition system (EDIS), which has coil packs instead of a distributor and is more of an engine function. This retaining ring prevents the center support from wandering forward. This cookie is set by GDPR Cookie Consent plugin. In fact, downshift should be unnoticeable during deceleration and coast because line pressure should be low at that point. The fix was to replace the intake manifold. Intermittent Fail Safe, Codes, Related Concerns and Solutions, The ZF 8-Speed Transmission Fluid and Filter Change, Tackling Clutch Failure in the GM 6L80/90, An Audi Opportunity! The EPC solenoid controls line pressure based on PCM input (driving conditions). This cover contains line pressure at the 1-2 shift accumulator. Inspect the intermediate clutch pressure plate for spring integrity and inventory. A seal lip pointed the wrong way is a guaranteed leaker. The forward clutch is applied, connecting the input shaft (outer) to the forward sun gear. During this time, the coolant pressure went from 17 psi to 0. As a result, Ford engineers added a spring to give the 3-4 shift valve a helping hand. Park is the last manual detent when the linkage is full forward. But then, the 4R70W is also not a great place to end your search either. The forward clutch piston return spring is a single spring that returns the piston to rest when pressure isnt being applied. Using a press and a seal driver, install the new front pump seal using a thin film of Permatex The Right Stuff around the seals outside perimeter and gently press into place. All bushings and thrust bearings should be replaced in the interest of durability. The 4R70W, a Ford transmission, is an evolution to the popular AODE and is often used interchangeably. 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. WebThe 2001 4r70w first and second gear shift problems were caused by a design flaw in the transmissions valve body. ^^Agreed your pressures look good to me. This drain hole must be at 6 oclock. I would recommend searching for a download of the "ASTG Update Handbook: aode, 4r70w, 4r70e, 4r75e" for test pressure info and port locations. 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. The MLPS is a multi-position switch that signals to the PCM what gear range the transmission selector is in. Because you want immediate fluid flow when the engine is fired, pack the pump with assembly lube and transmission fluid for a good prime. Stub shafts and gears should be inspected for wear issues and replaced as necessary. Did you remove the valve body when you fixed your other problem? Electronically triggered solenoids are simple electromagnets. 1996-2004 Mustang 4.6L 2V 4R70W Transmission Gear Ratios. 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. Install a new overdrive band and anchor it to the pin. They are bad for breaking at the snap ring land. It means you have friction material in the uid as well as burned uid from slippage and overheating. 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. Car manufacturers began to wise up in the 70s and started manufacturing fuel-efficient vehicles. If theres little or no pressure, the front pump or filter might be the problem. 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.
