What is a transmission control module?
Unusual gear shifts can happen due to poor transmission control modules and a multitude of issues related to them. The car computer can send incorrect messages when detected by your transmission machine.
These wrong indicators are displayed in the form of an engine indicator in your car to notify the drivers of a registered error. This means that the TCM works in conjunction with the transmission and the engine for optimal performance. The TCM uses the data collected to calculate optimal gear shifts.
When the engine and transmission get into optimal operation the engine performs best. Bad throttle management can lead to engine health issues and engine problems.
