Transmission Removal

Transmission





All vehicles

NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms can occur while the vehicle relearns its adaptive strategy. The customer needs to be notified that they can experience slightly different upshifts (either soft or firm) and that this is a temporary condition and will eventually return to normal operating condition.

NOTE: If transmission disassembly or installation of a new transmission is necessary, drain the transmission fluid. Install the transmission fluid pan drain plug when finished.

NOTE: If the transmission is to be removed for an extended period of time, support the engine with a safety stand and a wood block.
