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 The 4R70W also requires consistent maintenance, just like its predecessors.This way, you will have an incredibly powerful transmission. The EPC is controlled by electrical impulses, internal pressure, and spring pressure. Staggering these gaps helps contain line pressure at the source. 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. All bearing surfaces should have been lubricated. Rollers become pitted, and this isnt always visible. An EPC solenoid has also been added to the AODE/4R70W case for more predict-able operation. Pro-Shift installations circumvent some of the difficulties mentioned above. Too much line pressure and you can break the transmission case. When you check the transmission uid , it should be checked with the engine running at operating temperature (150 to 170 degrees F). This installs exactly as you see here with a cover and C-clip. Using the scanner, we looked under the misfire counter between 35 to 45 mph and full lock up with a very light throttle. There it was a misfire. Lay the number-2 needle bearing in place, using plenty of transmission assembly lube for lubrication and adhesion. Also install the input shaft sealing rings at this time. Begin the pump inspection by verifying the bolts are torqued correctly and the stator support is secure. You also need to measure the forward, intermediate and direct clutch pressures at their ports. 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. 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. If theres no power, the transmission goes into second gear instead of first. The 4R70W transmission tends to slip on the 1st gen Ford Crown Vic. The valve body is responsible for controlling the flow of fluid The cookies is used to store the user consent for the cookies in the category "Necessary". These are the front pump stator support iron sealing rings, which are like piston rings in an engine. 1. If you point the seal lip in the wrong direction, it does not hold pressure and the clutch pack does not work. Most Common Ford Crown Vic Problems 1st Generation 1993-97 1. As a result, Ford engineers added a spring to give the 3-4 shift valve a helping hand. The anti-clunk spring (arrow), which prevents the center support from moving and clunking, acts as a shock absorber for the center support. Powertrain Expo Each transmission build shop has its own approach to assembly. 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. Cookie Policy - Do a leak check with compressed air. According to ASTG all your line pressures are fine. Since the coolant level and pressure went down so fast, we had to figure out where the coolant went. Clutch clearances should be .040 to .059 inch. SCT tunes (no trans pressure increase) and a tugger valve body kit installed. Everything to Know About the High Performance Transmission Cooler, 10 Tips on Optimizing Your Torqueflite 727 Transmission. The MCCC is off. 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 your reassembly of subassemblies in a logical order from the rear of the transmission forward. The AOD has dual input shafts (inner and outer); the AODE/4R70W has one, which splines into the forward clutch. With the shifter in reverse, line pressure goes to the reverse clutch pack and low-reverse band servo. The 2-3 shift accumulator drops into its cavity. Theyre either on or off or on/off in a duty-cycle (pulse) pattern. If you have no engine braking in manual 1, the problem isnt electronic. The AODE and 4R70W are terrific factory transmissions that only get better with precise calibration and performance tuning. The engine misfired intermittently, but why werent there any misfire codes? What gives? Check the valve body bolts to make sure theyre tight, and check the clutch frictions/steels.

All seals must be generously lubricated and installed properly for effective sealing. Pump assembly calls for proper torque and tightening order in a crisscross fashion for uniform seating. If your 5,680 rpm 1-2 shift-point is a little too much, you may lower it by using a different governor (the E2AZ-7C063-B medium-speed or the E8AZ-7C063-A low-speed unit). 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. Pressure all by itself doesnt move the 3-4 upshift valve. 4R70W tcc lock up in 1st gear. Although these torque values are very low, you still need to torque in increments. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Could have rolled a lip seal. I shifted down into 1st and it won't move, feels like it's in neutral. This center support carries the planet carrier. 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. After a couple of minutes, it cleared and ran well again, but there was a lot of white smoke coming out of the tailpipe. The torque converters turbine drives the input shaft. Check the uid level and line pressure. Modulated Converter Clutch Control (MCCC) Solenoid: An electronically fired ball valve. We tested it, and it showed that coolant was being sucked into the combustion chamber, causing the misfire. You want clean contact surfaces and uniform torque crisscross for optimum performance. Make sure all holes line up, then mate and secure the pump halves. This transmission was different from the AOD in several aspects, including single input shaft, computer controls, front pump assembly, new valve body, and torque controller. Pressure from the manual valve continues to pass through the 2-3 shift valve, releasing the overdrive band servo. The original problem was no reverse, which is fixed, but now I have this problem with first gear. 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. Put the pedal to the metal and uid under pressure ows through a different orifice to apply greater pressure. The direct clutch hub goes up against the number-7 thrust bearing. Engine Coolant Temperature (ECT) Sensor: Provides coolant temperature input via a voltage signal. Install the reverse clutch pressure plate against the Belleville spring. Install the forward clutch piston seals. If the downshift solenoid has any issues, it may cause the vehicle to behave erratically when downshifting. Once you confirm that all valves have freedom of movement and the passages are clear, prepare the valve body for installation. 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. With that, Irvin reassembled the transmission. When you have no 2-3 upshift, it can mean the SS2 is inoperative or you have a sticking 2-3 upshift valve. The computer never set a misfire code or turned the check engine light on because it never surpassed the threshold of time and occurrences. In this edition of our special Violence in Chicago series, NBC 5s Stefan Holt sits down with a group of Chicago teens to discuss the struggles they face on a daily Power passes through the torque converter to a single input shaft, which makes it different from the AODs twin input shafts. I put them in exactly as they came out and possibly could be that. Or it could be a number of sensors both internal and external. 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. About Us - This allows for proper seating and prevents warping. Use plenty of lubrication as a pre-lube and for adhesion. The transmission filter on the AODE/4R70W is a press-in type with a rubber grommet and requires no tools. Keep in mind, Reverse does not use a solenoid 'like' the forward gears. I have measured the plate bowing upwards as If it is brown or otherwise dark in color that is a clue. 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 controlled by the PCM. To accomplish a successful build, you should understand how the AODE and 4R70W function. Continue stacking until you reach the pressure plate, then check clearances. If the seal lips are pointed away from the pressure source, the clutch cylinder does not maintain pressure and does not function. If the SS1 solenoid remains energized or the 1-2 shift valve sticks, you dont get a 1-2 upshift. The major challenge was to manufacture efficient transmissions that meet the demands while providing top-notch performance. 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.

Four iron sealing rings install on the output shaft. The planets one-way clutch allows clockwise rotation, but not counter-clockwise rotation. And since then, several regulations and rules to considerably improve the quality of air and fuel efficiency have been published. Not enough line pressure and you get slippage. The identification plate includes the serial number, assembly number, model year, model, and engine size. Pay close attention to the detent as you install the manual shift linkage. Apply uniform pressure to the piston while feeling for a smooth transition. Account. Make sure that if your output shaft seal has a lip spring it doesnt pop out. Yet another issue could be the low-reverse one-way clutch. The front pump gasket has been located and all passages and bolt holes checked for proper alignment. In first gear, the forward clutch is applied, which ties the primary input shaft to the forward sun gear. Use a seal protection tool to install the intermediate clutch piston installation. Shift up to 2nd and it moves forward just fine, same in Drive. As mentioned earlier, no stock transmission is perfect in every aspect. S1. Use assembly lube as an adhesive to install the thrust washer. Check this pressure plate for freedom of movement before installing the pump. Legal/Privacy. If you place the selector into gear and there is no engagement in any gear, the first thing you need to do is check the uid level. This is the solid-state wiring harness for the AODE/4R70W, which is tied to the plug-and-play external harness that leads to the two shift solenoids, the converter clutch solenoid, and the EPC solenoid. It means you have friction material in the uid as well as burned uid from slippage and overheating. Use plenty of lubrication, then drive the seal in. Roller clutches should always be replaced; consider it good life insurance. The 1-2 shift valve remains as is. Please register or login to enable Dark Mode. There are other issues with these valve bodies you should look for, like flooding solenoids, shift valve spring weakening, and leaking plugs. You dont want to feel downshift. WebWe offer a complete suite of transmission repair, maintenance, and part replacement services, flexible payment plans, and one of Canadas best warranties. Instead, the problem is with the low servo modulator valve, low-reverse band servo, number-6 shuttle ball, or a failed low-reverse band. Torque the bolts in a strict pattern to prevent warping. As you mate clutch assemblies, ensure complete mating and seating before loading each assembly into the case. Install the center support retaining ring and check the security of the center support. Twist and wiggle the stub shaft and feel for proper seating. Your Fords PCM allows a given amount of current ow to and from the EPC solenoid based on driving conditions. Pressure causes the lip to seal. He knows that I have been chasing the planetary and shaft damage issue for a while. 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. Cart The AODE/4R70W transmission has a high-efficiency front pump for improved volume. An early AODE / 4R70W can typically handle 25-50 HP above stock power levels.

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. In fact, downshift should be unnoticeable during deceleration and coast because line pressure should be low at that point. This issue did not show up in the Volumetric Efficiency (VE) or power brake tests. Does the engine stall when the transmission selector is placed in gear? 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. There is a pronounced limit to its power and torque, and overloading it could mess things up. The AODE/4R70W is a 4-speed, rear-drive automatic overdrive with electronic control, hence the AODE designation. An AODE/4R70W not going into gear could mean problems with the forward clutch piston sealing and check balls. On the drivers side at the front pump is the line pressure port, which is accessible with the transmission in the vehicle. The harness protects the wiring. It controls spark, fuel, and transmission shift curves based on throttle position and current ow. Darkness indicates contamination and overheating. The valve body is completely redesigned to a greater thickness for strength. The intermediate stub shaft splines into the planet carrier. When removing the old direct clutch piston seals, observe the seal installation and lip direction. It could also be a misfire. If your AODE/4R70W experiences no 3-4 upshift, it is a sticking 3-4 shift valve, overdrive servo issue, or a failed overdrive band. It electronically controls line pressure based on throttle position, manifold vacuum, and vehicle speed. 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). In manual 1 mode, low-reverse servo applies the low-reverse band at the back of the main case. Copyright 2006-2020 GEARS Magazine.
