Cd4e transmission shift

Sifter position D is missing at startup after overhauling of transmission. There were mechanical damage on forward clutch which replased. Also Master kit and new gasket set installed. All other gears are working now normally. After accelerating with L2 up to 80 km/h D switch on normally and OD over speed 120 km/h. At lower speed both slipping and switch off at speed 20 km/h. What shall be the problem?

SOURCE: E4OD Trans stays in OD no matter where the shifter position is.

Transmission Description The E4OD transmission is a fully automatic, electronically controlled, four-speed unit with a torque converter clutch. The main operating components of the E4OD transmission include a torque converter clutch, six multiple-disc friction clutches, one band, one sprag one-way clutch and two roller one-way clutches that provide for the desired function of three planetary gear sets. Transmission gear selection in the (D) range and converter clutch operation is controlled by the powertrain control module (PCM) (12A650). Operating conditions are relayed to powertrain control module by various sensors throughout the vehicle. The powertrain control module compares these conditions with electronically stored parameters and logically determines how the transmission should operate. A torque converter (7902) couples the engine to the transmission gearset via the input shaft (7017) and the torque converter impeller hub. The impeller hub provides engine rpm to the positive displacement pump. The flow from the pump is proportional to engine rpm, and excess pump capacity is exhausted back to the pump inlet. The input shaft transfers power into the transmission gearset. The power input is controlled by the application of the torque converter clutch, which is scheduled through the powertrain control module. The application of the piston plate effectively replaces the hydraulic coupling between the converter cover and the turbine with a mechanical coupling between the converter cover and the turbine hub. This mechanical coupling helps improve fuel economy and wide-open throttle performance by eliminating converter slip. Transmission shift selection and torque converter clutch operation are controlled by the PCM. They are calibrated to provide the optimal transmission state. This state is commanded to the transmission solenoid body. In the (D) range, automatic operation of all four gears is possible. The transmission control switch, located on the vehicle's shift lever disables overdrive operation and enables automatic operation through the first three gears. Whenever the ignition switch is turned on, the vehicle will automatically provide overdrive operation regardless of the switch position the last time the vehicle was running. Manual gear selection is available in the 1 and 2 range. Second gear is commanded when the gearshift selector lever is in the 2 range and when downshifted into the 1 range at speeds above approximately 56 km/h (35 mph) (for diesel 48 km/h [30 mph]). First gear is commanded in the 1 range at start-ups and when downshifted into 1 range below approximately 56 km/h (35 mph) (for diesel 48 km/h [30 mph]). Any reference to intermediate brake drum or direct clutch cylinder are one and the same.

I think this is your problem:

Programmable Speedometer/Odometer Module (PSOM): Description: The programmable speedometer/odometer module receives input from the rear brake anti-lock sensor, which is mounted on the rear axle differential housing. The PSOM processes this input signal information and relays it to the powertrain control module and the speed control module. This signal tells the powertrain control module the vehicle speed in miles per hour (mph). Used as an input in determining shift scheduling and electronic pressure control. Symptoms: Harsh engagements, firm shift feel, abnormal shift schedule, unexpected downshifts may occur at closed throttle, abnormal torque converter clutch operation or engages only at wide-open throttle (WOT). May flash transmission control indicator lamp. Diagnostic Trouble Codes: 452, P0500, P1500, P1501, P0503

SOURCE: 2002 Volvo v70-Transmission is shifting hard in lower gears

Find a transmission servicer that is not afraid of tackling a Volvo problem. This is probably why the car was for sale in the first place. Good luck!

SOURCE: why wont my clutch disengage? its hard to shift gears

It sounds like you got air in the lines after changing the stuff. you will need to bleed it like you do the brakes. it may take two people to to do tis. one to pump the clutch while the other works the fitting to let the air out. I hope this helps, and please be kind with a thumbs up. I need to good marks. Raz

Gear shifting stuck

I am afraid your mechanic very well could be correct. If the transmission was run low on fluid to the piont that the clutches were slipping, there could be some severe damage inside the transmission that may require an overhaul.

I think if it was my vehicle, I would pull the pan off and check to see how much debris is in the bottom of the pan. If you see a bunch of metal flakes, then it is transmission rebuild time. If there is only a bunch of the normal (black) clutch material, I would try replacing the filter and refilling it with fresh transmission fluid and see if the shifting improves.

The o/d light flashes and the transmission wont shift into overdrive on my 2007 mercury mariner. it has the cd4e transmission. i changed the tss and the solenoid pack on the valvebody i get code 1870...

are you missing 2nd gear too? shifting 1 to 3? If yes, 2-4 gear band is bad. common issue.
just google cd4e no overdrive and see comments. You have 6/60powertrain warranty or if extended service plan even more coverage. call dealer with VIN to se if under warranty

Transmission only goes in reverse

make sure check transmission for proper fluid level and color.if fluid looks black or smell burnt.change fluid and filter.check manual linkage for proper adjustment.if all is good.your transmission oil pump bad or the over drive unit has damage roller clutch.or the forward clutch has burned clutch plates and damage pistons and seals.you probably need to buy another transmission or get an overhaul.

1995 saab manual transmission shifted to nuetral at an intersection then unable to shift back into gear again

Pull up the leather shifter boot (it's attached with an elastic cord around the base, so just tug upward on it)

look for a little white plastic extension attached to the shifter at the base. This is what locks the car into reverse once the key is removed.

From use/wear, this will sometimes rotate and drop down on the shaft and prevent the sifter from going in any gear.
