Unveiling the Mystery: Is Transmission Control Module Covered Under Warranty?

The transmission control module (TCM) is a vital component of your vehicle’s transmission system. It is responsible for controlling the shifting of gears, ensuring smooth and efficient operation. However, like any other part of your car, the TCM can malfunction or fail, leading to costly repairs. One of the most important questions that car owners have is whether the TCM is covered under warranty. In this comprehensive guide, we will delve into the details of TCM warranty coverage and provide you with all the information you need to know.

What is a Transmission Control Module (TCM)?

The TCM is an electronic control unit that monitors and adjusts the transmission’s operation. It receives input from various sensors and switches, such as the speed sensor, throttle position sensor, and gear selector lever, and uses this information to determine the appropriate gear for the current driving conditions. The TCM then sends signals to the transmission’s solenoids and actuators to engage the desired gear.

Is the TCM Covered Under Warranty?

The coverage of the TCM under warranty varies depending on the manufacturer and the specific warranty terms. However, in general, most manufacturers offer a powertrain warranty that covers the transmission, including the TCM. The duration of the powertrain warranty typically ranges from 5 to 10 years or 60,000 to 100,000 miles.

What is Covered Under the Powertrain Warranty?

The powertrain warranty typically covers the following components:

• Engine
