A transmission control unit (TCU), also known as a transmission control module (TCM), or a gearbox control unit (GCU), is a type of automotive ECU that is used to control electronic automatic transmissions. Similar systems are used in conjunction with various semi-automatic transmissions, purely for clutch automation and actuation.
In late May 2022, Ford issued a recall for the 2021 Ford Mustang Mach-E due to an unintended acceleration issue resulting from the powertrain control module functional safety software potentially failing to detect a software error, resulting in unintended acceleration, unintended deceleration, or a loss of drive power.

A power-train control module, abbreviated PCM, is an automotive component, a control unit, used on motor vehicles. It is generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the TCU, and the Body Control ...
The transmission fluid will quickly overheat, not to mention the repeated impacts on the stator clutch (next topic). Also, overheating transmission fluid causes it to lose viscosity and damage the transmission. Such abuse can in rare cases cause the torque converter to leak and eventually stop functioning due to lack of fluid.
The Aisin AW TF-8# SC series is a 6-speed automatic transmission designed for use in transverse engine applications produced by Aisin Seiki. It is built in Anjō, Japan, [1] and is also called TF-80SC [2] (AWF21), AF40-6, AM6, [3] AW6A-EL and TF-81SC (AF21). [4] All-wheel drive transfer cases can be fitted to the AWTF-80 SC.
This failure is the most common and easiest to detect, and is affected by reduction of the active channel of the transistor in gate sinking and depletion of the donor density in the active channel for hydrogen poisoning. Degradation in gate leakage current. This occurs at accelerated life tests or high temperatures and is suspected to be caused ...
