Auto Repair: Fix Transmission Shift Problem Ford 5R55E Explorer more - 1AAuto.com

Ford used the 5R55E in many rear and 4 wheel Drive applications. It is a good transmission but is susceptible to the valve body gasket "blowing out." The symptom of this in our vehicle was that the transmission missed second gear under acceleration but found a higher gear when we let off the gas pedal. This is an easy problem to diagnose and only requires basic tools. Pull your transmission pan down, remove your valve body and see if either the gasket between the plate and transmission is damaged (as on our Explorer) or the gasket between the plate and valve body is damaged. If they are then you have an inexpensive rewarding fix. If they aren't you can put your transmission together and know you may have a more expensive problem. This transmission was used in Ford Aerostar, Ranger, Explorer, Thunderbird, Mustang Mazda B-Series pickup, Mercury Mountaineer, Lincoln LS and Jaquar S-Type. This problem is more common to the mid to late 90s models. Torque specifications for the valve body to transmission bolts are 6-8 foot lbs or 70-90 Inch lbs. The bolts that hold the transmission pan on are 10 foot lbs.

Hi, i have a Explorer 96 4 x 4 XLT 4.0. I have a problem shifting from 3 to 4 and from 4 to 5, i have already did the following, change de tranny oil and the filter, change the air filter, gas filter, oil and filter, change canister, spark plugs, wires, new thermostat, cleaned the cooling temperature sensor, the maf sensor, the air temperature sensor, even new radiator, new band, cleaned and lubricated the band tensor.My question is could be the TPS or speed sensor and not the valve body gasket?

@fayett10 If you bring it to a transmission shop they could test all of the pressures in the valve body for you to see if everything's working correctly.
