  • How to Check the Operation of a Transmission Control Module in a Car – A Comprehensive Diagnostic Guide

    An automatic transmission is one of the most advanced and complex components in a modern car. It combines precise mechanics, intricate hydraulics, and sensitive electronics. The brain of the entire system is the transmission control module (TCM)—an electronic unit responsible for analyzing data from dozens of sensors and making gear-shifting decisions in fractions of a second.

    When this crucial component fails, the comfort and safety of driving drop drastically. In the following article, we explain how to correctly diagnose and check the operation of an automatic transmission control module, what symptoms to look out for, and what solutions to choose in case of failure.

  • Burnt Automatic Transmission Control Module – Symptoms, Diagnosis, and an Effective Solution

    The automatic transmission is an incredibly complex system, combining advanced mechanics, hydraulics, and precise electronics. The brain of this entire operation is the transmission control module, commonly known as the TCM.

    Unfortunately, due to harsh working conditions, these modules can be prone to serious failures. One of the most critical faults is the physical burning of the electronics inside the module. In the following article, we will take a closer look at this phenomenon, discuss the characteristic symptoms, and advise on the most cost-effective way to deal with this expensive problem.
