The Transmission Control Module (TCM) is the system that enables efficient gear transmission in automatic vehicles by virtue of receiving the signals from sensors and controlling the gear shift actuators in response, enabling a smooth gear shift as per drive requirement. Manual transmission vehicles usually do not have a TCM. Hence the right suitable coding & programming is utmost important for the optimum performance of the TCM of the Car. Kindly contact AMA auto Sharjah if you need TCM coding or programming for your German Car.
