Use a little leverage to install the snap ring. After you add liberal lubrication to the output shaft seal, press it in. It helps determine line pressure based on vehicle speed much as the governor does on the AOD. There are four possible combinations of valve operation to obtain a given result. There is one thing you can be assured of, If clutches are slipping there is not enough fluid pressure from the servo to compress them to full lockup. Install the number-7 C-clip. Lose the spring and you will have slip-yoke leakage. Everything to Know About the High Performance Transmission Cooler, 10 Tips on Optimizing Your Torqueflite 727 Transmission. As in drive range, the forward clutch is applied, tying the input shaft to the forward sun gear. So 1st gear can go out but youll still have man 1st. Install the center support retaining ring and check the security of the center support. Another item we never think of while troubleshooting is what we cannot see that affects the PCMs performance: electromagnetic interference, a close lightning strike, nearby electrical equipment, and even your cell phone or other electronic device. This keeps the transmission in first gear. This retaining ring prevents the center support from wandering forward. Ford developed the AODE and 4R70W to achieve cohesive engine and transmission function in 1991. It can also mean reverse clutch piston seal problems. Electronic Pressure Control (EPC) Solenoid: Your AODE/4R70Ws pace-maker. It can pop out if it is not completely seated. This installs exactly as you see here with a cover and C-clip. Check this ring carefully for proper seating. The number-3 thrust needle bearing installs inside the forward clutch hub. 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, delayed/no lock-up, harsh 2-3 shift, loss or slipping in forward gears, direct clutch failure or loss of third and fourth gears, low pressure or harsh shifts and front The only inter-changeable components are geartrain related. Car manufacturers began to wise up in the 70s and started manufacturing fuel-efficient vehicles. Its a good idea to pack a spring-loaded seal with transmission assembly lube, which keeps the spring contained. Any seal bind is a guaranteed leak. The AOD efficiently replaced several older transmissions that Ford put out, including the C4, C5, and FMX. What axle gear ratio are you ordering in an F-350 with a 7.3L gas engine? Install the forward clutch frictions alternately between the steels. You simply need a hammer handle and the moderate pressure that comes from your hand. The 4.6L V-8 needs the 2.84:1 and 1.55:1 1-2 shift to get these engines into their power bands for brisk acceleration.

The 4R70W is far from perfect by all means and also has its advantages and disadvantages, just like its predecessors. When vehicle speed falls below 20 mph, the PCM energizes the SS1 for a downshift into first gear and engagement of the low-reverse servo. However, fuel-efficient automobiles were environmentally and economically friendly and could cover more miles with far less fuel. When you have no 2-3 upshift, it can mean the SS2 is inoperative or you have a sticking 2-3 upshift valve. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. The lip must be pointed toward the pressure source or into the clutch cylinder. 2. Line it up for the overdrive band servo piston. Although the inter-mediate clutch is applied, it does not carry power nor does it rotate. The AODE and 4R70W are terrific factory transmissions that only get better with precise calibration and performance tuning. 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. Renew Subscription Bought it with a supposed rebuilt transmission, but apparently it wasn't all it was cracked up to be. A bad or failing solenoid may cause the vehicle to experience hard or erratic shifting when slowing down or coming to a stop. The uid pressure is the same as second gear in drive range. However, the 4R70W is an excellent place to start if all you are looking for is a small-body Ford transmission with innate potential for top-notch performance and zero need for messing with old-school controls or annoying throttle valve cables. Pressure against the seal lip is self-sealing and fail-safe. This is the direct clutch, steels, and thrust/needle bearings. Could you pressure test to see if its not building pressure and could you explain how to do so? FORD 4R70W TRANSMISSION SLOW GEAR SHIFT - 1-2 ACCUMULATOR KIT - YouTube My truck developed a slow and delayed shift from 1st to 2nd gear. Although the automatic overdrive transmission was relatively new, it still bore several features of old designs. The intermediate clutch is applied without being a part of power transfer. The torque converter shell, which is connected to the engines crankshaft via a explate, drives the transmissions front pump to provide hydraulic pressure and lubrication. Staggering these gaps helps contain line pressure at the source. The 2-3 shift valve moves under pressure against spring pressure. The MCCC gets pulsing signals from the PCM. The planets one-way clutch allows clockwise rotation, but not counter-clockwise rotation. Slowly walk the tool around, protecting the seal lip. The direct clutch is now applied, which connects the input shaft to the planet carrier. Be sure to lubricate the rollers generously. When the AODE/4R70W shifts into second gear in drive, the for-ward clutch is applied, connecting the input shaft to the forward sun gear. Install a new overdrive band and anchor it to the pin. Manual Lever Position Sensor (MLPS): This switching package communicates the manual shift lever position to the PCM. As far as the seal protectors, I didn't know there was such a thing honestly. 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. An AODE/4R70W not going into gear could mean problems with the forward clutch piston sealing and check balls. A lone sealing ring (PN 87054-S96) goes in the top groove. Protect your eyes and face for this step. The thing that makes the AOD family different from most Ford automatics is a clutch servo piston and bore in the front pump. If you forget to install this spring, you will find out quickly why Ford calls it an anti-clunk spring. Transmission Control Module: Buyers Guide for Classic Cars. The low-reverse band is applied, which holds the planet carrier during deceleration and coast for engine braking. Spring pressure here determines shift firmness. 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. 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. Copyright 2006-2020 GEARS Magazine. Apply uniform pressure to the piston while feeling for a smooth transition. BlueScreen MS/Extra Newbie Posts: 4 Joined: Thu Jan 19, 2017 6:48 pm. Does it happen in one gear range or in all?

Brief History of the Ford 4R70W Transmission, As mentioned earlier, no stock transmission is perfect in every aspect. 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. Pick-up not installed correctly,clogged filter,low fluid. 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. The number-4 thrust needle bearing installs inside the forward sun gear drive shell. The 1-2 shift valve remains as is. 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. Begin with the simplest, most commonsense issues. It could also be a misfire. 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. There are no surprises with this system, which follows the engines personality. This allows full pressure to the overdrive servo and band. Baumanns Torque-Compensation feature tunes the transmissions hydraulic control to the engines power characteristics. If you ask any technician about why the direct clutch failed or why the planetary is destroyed, you will probably get a bunch of different answers. Adjust clearance via the clutch plates, which are .071 to .067, .081 to .077, .091 to .087, or .101 to .097 inch, using a depth micrometer. I'm having a problem with my transmission in my 2003 Ford F-150 4x4 (4R70W). Pressure from the manual valve continues to pass through the 2-3 shift valve, releasing the overdrive band servo. Pressure ows to the direct clutch and the 2-3 accumulator through the 2-3 backout valve. PS. The AODE/4R70W front pump is high-efficiency aluminum rather than iron. Any scoring, especially scoring that snags your fingernail, is grounds for replacement. I would start by removing the valve body and inspecing it first. The lap joint must meet head-on and be perfectly aligned. Give these rings and grooves abundant lubrication. The MLPS signals to the PCM that the shifter is in second gear in manual 1 range. As a result, Ford engineers added a spring to give the 3-4 shift valve a helping hand. Seals and thrusts should be installed wet with transmission assembly lube, though not all shops do it this way. were also part of its components. Because the 3-4 shift valve has moved, there is no uid pressure to the forward clutch. The planetary one-way clutch overruns. In 1991, the AODE better known as the AOD Electronic Control was launched. Click the button below and we will send you an exclusive deal on this book. Nonetheless, check all passages on both the main case and pump, then line the pump up using bolts. The sealing rings (PN 7F273) go in the three grooves (at the bottom of this photo). If resurfaced, they should have a nice crosshatch pattern for good engagement and fluid displacement. All that is needed now are clutch discs between the clutch plates. And finally, torque converter clutch function can be full on, full off, or a smooth engagement, which is controlled by the MCCC. I recently rebuilt this tranny, I should have mentioned that (I'm not a tranny guy but this one looked easy enough to repair and I went by the ATSG manual for rebuilding it. The manual shift linkage and manual valve line up like this. Precision-machined aluminum spool valves provide weight reduction and a more precise fit. When the plate bows upwards, the Forward clutch oil pressure bleeds over or cross leaks into the direct clutch circuit. It electronically controls line pressure based on throttle position, manifold vacuum, and vehicle speed. Manage Preferences - The EPC solenoid controls line pressure based on PCM input (driving conditions). Online Buyer's Guide At WOT, you want high line pressure for firm clutch and band engagement. Remove the pan and inspect the filter. 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. Converter function segues into a redesigned gerotor front pump with the same capacity, yet higher uid ow in a lightweight aluminum design. But when we checked the coolant for exhaust gases, there wasnt any. If it is brown or otherwise dark in color that is a clue. This drain hole must be at 6 oclock. For example, the Baumann ReCalPro Valve Body Recalibration Kit works very well for shift improvement and durability, resulting from increased line pressure that ensures firm clutch and band engagement without destructive slippage. No 1st Gear Been having issues with the truck accelerating slowly. Servo apply pressure is controlled by the low servo modulator valve. JavaScript is disabled. While this might not be a bad idea, it could lead to a clearance issue. Terms of Service - Of course, like every transmission out there, they have their common concerns. 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 forward clutch friction and steel clearances should be .050 to .089 inch. Shift up to 2nd and it moves forward just fine, same in Drive. Electronically triggered solenoids are simple electromagnets. 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. Be very careful not to scratch the clutch piston. Have you checked the fluid for proper level and burning SCT tunes (no trans pressure increase) and a tugger valve body kit installed. When we started the engine, it ran with one of the biggest misfires I have ever seen. Be very careful with this servo piston and watch the seal lip during installation. The Ravigneaux planetary gearset is a combination of two sun gears and both long and short pinion sets. Once you have the converter seated it is Generously lubricate the seal lip with assembly lube. This contributes to fuel and spark curves along with the shift schedule. Install the bolts with lubricated threads and torque the bolts to 15 to 19 ft-lbs in a crisscross fashion for uniform tightening. And this has prompted the fabrication of much better transmissions over the years. Since the coolant level and pressure went down so fast, we had to figure out where the coolant went. Rollers become pitted, and this isnt always visible. Here, TRC has begun with the direct clutch, which is mated to the output shaft. Make sure all holes line up, then mate and secure the pump halves. Chrysler and General Motors followed swiftly with their respective versions. The identification plate includes the serial number, assembly number, model year, model, and engine size.

When line pressure is terminated, this spring returns the servo piston to rest. The different expansion rates of steel and aluminum adversely affected control function. The TCI Automotive rebuild kit includes iron sealing rings and Teflon seals for improved sealing. Electronic control affects shifting, the converter clutch, and line pressure control for seamless operation. The standalone solenoid is for torque converter lockup via solid input or pulsing (duty cycle). Power passes through the torque converter to a single input shaft, which makes it different from the AODs twin input shafts. 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 would recommend searching for a download of the "ASTG Update Handbook: aode, 4r70w, 4r70e, 4r75e" for test pressure info and port locations. This cover contains line pressure at the 1-2 shift accumulator. Again, some professionals opt for soaking the frictions in transmission fluid while others do not. If there are no serious signs of rotor or cavity wear, the pump can be returned to service. The drivers side has the manual shift linkage. How did the forward clutch drum look? Generously lube this assembly and install it, along with the cover. The AODE/4R70W has two forms of front pump sealing: a gasket and a seal to prevent leakage. Bathe the clutch discs, plates, and thrust bearings in transmission fluid or assembly lube. It wasnt all that different from the FMX 3-speed automatics since common FMX components such as the Ravigneaux gear train, etc. 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. 4R70W tcc lock up in 1st gear. This is the manual shift control and detent cam. This is the intermediate one-way clutch installed. Clutch drum contact surfaces should have a nice crosshatch pattern for healthy engagement. The direct clutch is applied, tying the input shaft to the planet carrier to the smaller inside input shaft (stub shaft). Did it come on all at once or did it arrive gradually? Clutch clearances should be .040 to .059 inch. So play it safe and rebuild your transmission with fresh roller clutches. Ford went to electronic control not only for engine/transmission cohesion, but also improved shift quality by removing the short-comings of mechanical control. SHARE THIS ARTICLE:Please feel free to share this article on Facebook, in Forums, or with any Clubs you participate in. Pay close attention to the seal status.

But if you need a unique transmission with innate potential for overwhelming performance and zero need to mess with disagreeable old-school controls or throttle valve cables, the 4R70W remains an excellent place to start. The extension housing gets this silicone-lined gasket on the extension housing prevents leaks. The AODE/4R70W is a 4-speed, rear-drive automatic overdrive with electronic control, hence the AODE designation. Re: 4R70W tcc lock up in 1st gear. Weak or soft engagement in any gear indicates insufficient line pressure from the source or leakage at clutch pistons or band servos. Torque the gasket bolts to 107 to 132 in-lbs, not ft-lbs. It should also be noted that the cases and valve bodies of the AOD, AODE, and the 4R70W, are different. Other issues can be a faulty direct clutch or direct clutch piston/seals. Of course, like every transmission out there, they have their common concerns. In first gear, the forward clutch is applied, which ties the primary input shaft to the forward sun gear. According to ASTG all your line pressures are fine. Make sure you wipe it off and put it back in for a more accurate reading. Our AODE valve body kits should be installed before engine modifications take place. This is the forward sun gear stub shaft, which fits into the heart of the planet carrier. Use plenty of lubrication on the center support bushing. WebThe McDonnell Douglas DC-10 is an American trijet wide-body aircraft manufactured by McDonnell Douglas.The DC-10 was intended to succeed the DC-8 for long-range flights. Top. Check the uid level and line pressure. I did replace scarf cut seals and made sure they went in properly. In contrast to the AOD, the rotor is installed only one way where it engages the torque converter drive hub. This cookie is set by GDPR Cookie Consent plugin.
