Where is the Automatic Transmission Control Module located? What does it do? How much does a new one cost?
Automatic transmission control module installation on 1996 BMW 318ti
The transmission control module and engine control module are located in the passenger rear of the engine compartment, behind a cover panel in the firewall. BMW have several bulletins about driveability issues relating to the control module. It is best to have a repair shop with BMW knowledge look at the car unless there is some specific reason (jump started the car the car wrong or module filed with water) you know the module is bad.
