   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.

3. Driveline shunt - Wikipedia

   en.wikipedia.org/wiki/Driveline_shunt

   Driveline shunt occurs when a vehicle gives an abrupt jolt while coming on or off overrun or freewheel. It is caused when the gearbox or other transmission linkages do not immediately relay changes in engine output to changes in wheel speed. There is a very brief delay before the backlash is taken up in a sudden, abrupt manner.

4. Electronic throttle control - Wikipedia

6. Throttle position sensor - Wikipedia

   en.wikipedia.org/wiki/Throttle_position_sensor

   Some engine control units (ECUs) also control the throttle position by electronic throttle control (ETC) or "drive by wire" systems, and if that is done, the position sensor is used in a feedback loop to enable that control. [1] Related to the TPS are accelerator pedal sensors, which often include a wide open throttle (WOT) sensor.
