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. Adjacent is the converter clutch solenoid, which receives a pulse input for smooth engagement. Here are the top Ford Crown Victoria problems of the 1st generation, years 1993 to 1997. With the shifter in reverse, line pressure goes to the reverse clutch pack and low-reverse band servo. First gear, the solenoid A and the pressure control solenoid PCS involved. The forward clutch piston installs using a Lip Wizard. Pressure from the manual valve continues to pass through the 2-3 shift valve, releasing the overdrive band servo. Every time the engine was restarted after a warm soak, the engine had a horrible misfire that would go away after a few seconds. Alternate the forward clutch plates with clutch friction discs. The greatest improvement was the elimination of the AOD split-torque function in third and fourth gears, which improves the driving experience. I shifted down into 1st and it won't move, feels like it's in neutral. Archive - If you have no engine braking in manual 1, the problem isnt electronic. SHARE THIS ARTICLE:Please feel free to share this article on Facebook, in Forums, or with any Clubs you participate in. Did you install the lip seals the correct way?

The shift solenoids open the shift valves when they receive power. Did you remove the valve body when you fixed your other problem? 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. With that, Irvin reassembled the transmission. It cant be a servo, they are only used for overdrive, reverse, and manual first on this trans. Subscribe Now As far as the seal protectors, I didn't know there was such a thing honestly. Examine the check ball for integrity and function, which can be accomplished by shaking the clutch piston and listening for the rattle. The reverse clutch discs alternate with plates. Rock these assemblies back and forth until the forward clutch is completely seated in the reverse clutch drum. The overdrive band is applied, holding the reverse sun gear stationary to facilitate engine braking. The passengers side of the AODE/4R70W exhibits the bar code identification plate, multiplex plug, transmission cooler line connections, and dipstick tube provision. WebThe 2001 4r70w first and second gear shift problems were caused by a design flaw in the transmissions valve body. Early 1999 4x4 w/ 215,000 and auto (4R100). 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. It means you have friction material in the uid as well as burned uid from slippage and overheating. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction. These cookies track visitors across websites and collect information to provide customized ads. Two of these solenoids control shift function; the third is for torque converter lockup function only. Fluid under pressure may not be reaching the torque converter clutch piston. Fourth gear in overdrive range has both the SS1 and SS2 on. First gear isnt usually the first to go (no pun intended) on the 4r70w. All of these items are checked by dropping the valve body and visually inspecting them. The next items to check are the number-3 and number-4 sealing rings. Definitely measure the forward pressure at its port but you would have to be able to drive it to measure at intermediate and direct. An AODE/4R70W not going into gear could mean problems with the forward clutch piston sealing and check balls. 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). Four iron sealing rings install on the output shaft. It allows the seals to transition smoothly without binding. It was 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. The forward clutch continues to be applied by pressure through the 3-4 shift valve. Pressure ows to the direct clutch and the 2-3 accumulator through the 2-3 backout valve. ^^Agreed your pressures look good to me. Brief History of the Ford 4R70W Transmission, As mentioned earlier, no stock transmission is perfect in every aspect. The AODE/4R70W rotating mass is similar to that of the AOD. Reply Like 09-14-2017, 12:01 PM Is the pump making hydraulic pressure and is pressure getting to the valve body, which is confirmed with a pressure gauge via the pressure port? Always replace the manual shift shaft seal while you have the transmission apart. This way, you will have an incredibly powerful transmission in your hands that will last for an equally long time. With all clutches and steels installed and clearances checked (.060.091 inch), install the snap ring. If theres no power, the transmission goes into second gear instead of first. Before mating them, make sure all contact surfaces are clean. Apply uniform pressure to the piston while feeling for a smooth transition. 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. You also want to service the torque converter (not shown) with 2 quarts of transmission fluid, which helps prime the pump. Sometimes the MAF sensor causes transmission problems. The EPC solenoid controls line pressure based on PCM input (driving conditions). With the locking converter comes a wider bellhousing than the AOD has. Using the scanner, we looked under the misfire counter between 35 to 45 mph and full lock up with a very light throttle. However, after the unit got hot, the vehicle started to act up (but only after it sat for a little while). Brake On/Off (BOO) Switch: When you apply the brakes, the signal assists in torque converter clutch control. If the spring is missing and cannot be found, replace the seal. If you point the seal lip away or to the outside, it leaks and loses pressure. Do not get this backward. In other words, are the two pump halves securely tightened? When there is no power, the shift valves are closed. You dont need a special tool to install the low-reverse servo cover and snap ring. Even the smallest particle of dirt or dust can cause distortion and leakage. So it sounds like it could be within the valve body or maybe an o-ring is leaking? Air pressure should be applied to serve as a valve function check. Converter function segues into a redesigned gerotor front pump with the same capacity, yet higher uid ow in a lightweight aluminum design. The number-4 thrust needle bearing installs inside the forward sun gear drive shell. When they work properly, the 4R70W and 4R75W is a reliable transmission. Please register or login to enable Dark Mode. Gears Magazine It can pop out if it is not completely seated. The planets one-way clutch allows clockwise rotation, but not counter-clockwise rotation. So 1st gear can go out but youll still have man 1st. Ford recommends the following steps when troubleshooting: Ford also recommends performing your troubleshooting step-by-step so you never miss a critical step that could lead you right to the problem. Cant get reverse gear? Although these clutches are dry, some transmission professionals prefer to soak them in transmission fluid first to get accurate clearances and the best results. Begin the pump inspection by verifying the bolts are torqued correctly and the stator support is secure. Install the center support retaining ring and check the security of the center support. The 2-3 back-out valve, as the name implies, regulates the feel of a 2-3 upshift. Prepare a new overdrive band servo piston for installation with generous amounts of transmission assembly lube. Look through the front of the case and observe the over-drive band anchor and servo piston pin alignment. Did the problem arise after transmission service or part replacement? The AOD efficiently replaced several older transmissions that Ford put out, including the C4, C5, and FMX. Torque the gasket bolts to 107 to 132 in-lbs, not ft-lbs. 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. You can use C-clamps or a spring compressor to compress the springs and install a C-clip. Another possibility is a leaking 1-2 accumulator cover or piston seal. It also means theres no pressure to the intermediate clutch pack. Sales & Info: 330-434-5216 Be sure you know the proper location for these sealing rings and seals. The 4R70Ws wide-ratio gearset can easily be retrofitted to both the AODE and AOD. Mark helpful 40 Its possible it could be something in the valve body but not if it wasnt touched. The plates should have a good crosshatch pattern. This keeps the transmission in first gear. The seal lip should be pointed toward the pressure source (inside the bore). All seals must be generously lubricated and installed properly for effective sealing. 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. Ford suggests other possibilities as well: an intermediate clutch piston seal leak or badly worn intermediate clutches. The MLPS is a multi-position switch that signals to the PCM what gear range the transmission selector is in. This installs exactly as you see here with a cover and C-clip. Fit the front pump, then slowly run the bolts down and pull the pump tight. 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.

Is the torque converter doing its job? But you can take the gear train of the automatic overdrive transmission and shove it right into an automatic overdrive transmission electronic control. 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. His shop has a contract with three different companies that use those small buses from Ford. 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. Ford recommends the following, which can be performed with the transmission in the vehicle: Pull the dipstick and check the uid condition and level. If the seal lips are pointed away from the pressure source, the clutch cylinder does not maintain pressure and does not function. (You can unsubscribe anytime), ATRA When we started the engine, it ran with one of the biggest misfires I have ever seen. Should either or both of these speed sensors fail, you may notice one or more of the following 3 issues: 1. 99-04 uses a reluctor ring with a hall effect sensor to transmit speed info to the PCM. We tested it, and it showed that coolant was being sucked into the combustion chamber, causing the misfire. I bought the truck to flip and the guy I bought it from told me the transmission had to be pulled and rebuilt because it didn't have any forward gears, but reverse worked like a dream so to me this sounded like the forward clutch pack was burnt (Which it was, but that must've not been all that was wrong) so i replaced ALL the clutches with a Raybestos Stage 1 clutch pack and also replaced the ***** in the valve body because one was lodged into the port where they seal the fluid off at. For a better experience, please enable JavaScript in your browser before proceeding. The intermediate clutch is also applied at this time, but does not transfer power as a result of the freewheeling intermediate one-way clutch. Ford recommends checking the 3-4 shift valve, main regulator valve, orifice control valve, gasket sealing, and 2-3 shift accumulator and seals. Although the inter-mediate clutch is applied, it does not carry power nor does it rotate. WebFord 4R70W/4R75W Transmission Information. We also use third-party cookies that help us analyze and understand how you use this website. Cages become damaged and at times this is even harder to see. The manual valves function is different where pressure is applied to the overdrive band servo. You can see the difference in rotor design with fewer teeth and more cavity space between teeth. Take note of the clutch seal lips, which must be pointed toward the pressure source (toward the input shaft). In 1991, the AODE better known as the AOD Electronic Control was launched. Pressure causes the lip to seal. Staggering the gaps helps the sealing rings hold pressure. Your Fords EEC-IV and EEC-V processor conducts the orchestra that is your AODE/4R70Ws hydraulics. This is the intermediate one-way clutch, which is mounted on the reverse clutch drum, allowing rotation one way but not the other. Bucko133. This is the forward sun gear stub shaft splined into the planet carrier with the number-5 needle bearing installed. (7 points) A car traveling on a flat (unbanked), circular track of radius R accelerates Inspect the reverse clutch Belleville return spring for cracks and distortion prior to installation. 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. And that is why you should know what it can and what it cant do. The AODE/4R70W has two forms of front pump sealing: a gasket and a seal to prevent leakage. One planetary member is driven while the other is held. Yes, valve body was removed and Sonnax Sure Cure kit was installed. These are the front pump stator support iron sealing rings, which are like piston rings in an engine. Do Not Sell or Share My Personal Information. 2.7K views 3 years ago. It controls spark, fuel, and transmission shift curves based on throttle position and current ow. The transmission must be removed to check torque converter function. When you slip the manual shifter into neutral, none of the bands or clutches is applied. The 4R70W, a Ford transmission, is an evolution to the popular AODE and is often used interchangeably. 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 major challenge was to manufacture efficient transmissions that meet the demands while providing top-notch performance. The fix was to replace the intake manifold. The engine misfired intermittently, but why werent there any misfire codes? Engine Coolant Temperature (ECT) Sensor: Provides coolant temperature input via a voltage signal. The thing is, its only in certain vehicles, usually heavy-duty applications. 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. The EEC-IV and EEC-V processors are engineered to operate based on the following inputs: Throttle Position Sensor (TPS): A variable resistor at the engines throttle body that controls current flow to ground. Lay the clutch discs and plates into the reverse clutch drum. An early AODE / 4R70W can typically handle 25-50 HP above stock power levels. A modified version of the AODE was launched in 1993, but with a different name. If clutch and servo are an issue then internal work is needed. You may also use the Ford tool (PN T92P-70023-A). It was not on the floor, so we figured the head gaskets were to blame. Did it come on all at once or did it arrive gradually? While this might not be a bad idea, it could lead to a clearance issue. Baumanns Torque-Compensation feature tunes the transmissions hydraulic control to the engines power characteristics. I would start by removing the valve body and inspecing it first. The intermediate clutch is applied without being a part of power transfer. What Are the Different Types of Transmission Fluids? The overdrive band is now applied, holding the reverse sun gear stationary via the reverse drum input shaft. Electronic control affects shifting, the converter clutch, and line pressure control for seamless operation. Use plenty of lubrication, then drive the seal in. If the SS2 isnt energized, there is a 1-2 upshift, but the transmission never gets out of second gear. The top clutch plate should be your plate. Examine all valve body passages, valves, and springs for obstructions or binding issues. Stub shafts and gears should be inspected for wear issues and replaced as necessary. Although these transmissions have a great deal in common, they are also very different, with limits in interchangeability. The torque converters turbine drives the input shaft. Then re-torque them for a final check. If you point the seal lip toward the intermediate clutches, you will have an internal hydraulic leak and no intermediate clutch function. The MCCC engages and disengages the torque converter clutch. Make sure you wipe it off and put it back in for a more accurate reading. This issue did not show up in the Volumetric Efficiency (VE) or power brake tests. Terms of Service - Shift up to 2nd and it moves forward just fine, same in Drive. 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 forward clutch is applied, connecting the input shaft (outer) to the forward sun gear. Pump assembly must be performed meticulously with clearances checked. Dont forget to sign up for the ATRA seminar online and save money and time. Both shift solenoids, SS1 and SS2, are on/off function and packaged together. 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. However, fuel-efficient automobiles were environmentally and economically friendly and could cover more miles with far less fuel. 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. In first gear in the drive range, the SS1 is on and the SS2 is off. During installation, watch the seals and protect them from distortion. Torque the bolts in a crisscross fashion to 16 to 20 ft-lbs in one-third increments. But opting out of some of these cookies may affect your browsing experience. GearStar Performance Transmission No cracks or chips and the snap ring land had no cracks. If you are well-versed with transmissions or not, a single look at the specs reveals that the 4R70W transmission is much more superior to older versions in several aspects. I just jumped into it last time without knowing what it was and it bit me. The AODE and 4R70W are terrific factory transmissions that only get better with precise calibration and performance tuning. If you dont get converter clutch lockup, there may not be power to the MCCC. Seals and thrusts should be installed wet with transmission assembly lube, though not all shops do it this way. 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. Ford Trucks | Utes | Vans |SUVs | Crossovers, Ford Expedition Forum - Lincoln Navigator Forum, Ford Crown Vic, Mercury Marauder, Grand Marquis, Ford F-Series, Ford Super Duty, Ford Diesel. With this sequence of events, pressure goes to the forward clutch pack through the orifice control valve and the 2-3 backout valve. The 4R70W differs from the AODE in terms of gear ratios. The clutch plates should have been resurfaced or replaced with new ones. Rollers become pitted, and this isnt always visible. 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. They are bad for breaking at the snap ring land. There are other issues with these valve bodies you should look for, like flooding solenoids, shift valve spring weakening, and leaking plugs. Be very careful not to scratch the clutch piston. Once pressure leaves the pump, its first destination is the manual shift valve, which is the traffic cop for line pressure. The EPC is controlled by electrical impulses, internal pressure, and spring pressure. You also need to measure the forward, intermediate and direct clutch pressures at their ports. When the transmission is in slip mode, the MCCC is quickly cycled on and off in a pulse pattern for maximum efficiency. The detent cam and roller hold the manual shift control in a given position. Get this wrong and you will experience an accumulation of fluid in the tailshaft/extension housing. Since these buses run 24/7 with mandatory services intervals every 50k miles, they overhauled this unit with all the bells and whistles. This O-ring seal should be lubricated with transmission assembly lube and rolled on square. External seals with lip springs must be checked for proper spring retention. According to ASTG all your line pressures are fine. Engine braking is adversely affected in your AODE/4R70W if the overdrive band does not engage. Darkness indicates contamination and overheating. Others install them wet. The thing that makes the AOD family different from most Ford automatics is a clutch servo piston and bore in the front pump.
