The transmission module is generally located under the vehicle or in the engine compartment, depending on the model and manufacturer. In most vehicles, the transmission module is usually installed below or next to the drive shaft. In some models, the transmission module may also be installed in the engine compartment, close to the transmission tank or engine control unit. A faulty transmission module may refer to a problem with the transmission control module (TCM). TCM is the electronic module responsible for controlling the transmission. It monitors and controls the operation of the transmission, including shift timing, shift sequence, hydraulic control, etc. If the TCM fails, it may cause the transmission to be unable to shift normally or operate abnormally, such as stalling during shifting, slow shifting, or inability to shift. This failure may require inspection and replacement of the TCM module to resolve. Gearbox acceleration errors can be caused by a variety o…
