MasterPro Electronics Transmission Control Module (TCM) - TCM092M
- Part #:
- TCM092M
- Line:
- MPE
The transmission control module, or TCM, controls automatic transmission shifting electronically and relies on feedback from the engine control module, transmission fluid temperature sensor, brake pedal position sensor, throttle position sensor, and more. Consistent communication from the TCM is imperative to maintaining appropriate gearing, fuel economy, and emissions for safe and efficient driving. Over time, transmission control modules may suffer damage or fail to operate or communicate as they should. When the transmission control module fails, either from normal wear, electric voltage spikes, or other damage, it can cause issues with shifting which can lead to poor vehicle performance and reduced fuel economy. You may notice your vehicle shifting especially hard or struggling to accelerate, or your vehicle may not shift into higher or lower gears at the wrong time and cause erratic RPM fluctuations. In some cases, it could even cause the torque converter to not engage or disengage properly, which could lead to dangerous driving conditions. Problems with the transmission control module may activate a Check Engine light or other warning, and you can have your https://www.oreillyauto.com/store-services/free-check-engine-light-diagnostic-testing">Check Engine light tested for free at your local O'Reilly Auto Parts store to help begin your diagnosis.
