Main Control Valve Body - Accumulator Body, Solenoid Body: Removal

WARNING: This page is about a different car, the 2002 Ford RV Cutaway, 2002 Ford Econoline, 2002 Ford E550 Super Duty, 2002 Ford E450 Super Duty, and 2002 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If the transmission has been disassembled to replace worn or damaged parts, and the valves in the main control valve body stick repeatedly from foreign material, the torque converter must be removed and cleaned by using a suitable torque converter/fluid cooler cleaner.

ALL VEHICLES

WARNING: On vehicles equipped with an auxiliary battery, both the negative and positive battery cables must be disconnected.

WARNING: On vehicles equipped with a 7.3L engine, both the primary and secondary batteries must be disconnected.

NOTE: All gasoline vehicles will have new adaptive shift strategies. Whenever the vehicle's battery has been disconnected for any type of service or repairs, the strategy parameters that are stored in the keep alive memory (KAM) will be lost. The strategy will start to relearn once the battery is reconnected and the vehicle is driven. This is a temporary condition and will return to normal operating condition once the powertrain control module (PCM) relearns all the parameters from the driving operating conditions. There is no time frame set for this process. If a concern is present during down shifts or converter clutch apply, it is not the shift strategy and will require diagnosis as outlined in the appropriate article.
The customer needs to be notified that they may experience slightly different upshifts (either soft or firm) and that this condition is temporary and will eventually return to normal operating condition.

Disconnect the battery.
Remove the transmission fluid level indicator.
