Powertrain Control Module (PCM)

On vehicles equipped with gasoline engines, the operation of the E40D automatic transmission is controlled by the powertrain control module. Many input sensors provide information to the powertrain control module, which then controls the actuators that affect transmission operation.

On vehicles equipped with diesel engines, the operation of the E40D automatic transmission is also controlled by the powertrain control module. However, some of the input sensors are different.
