The position of the transmission control module is found under the center console in the interior or under the hood near the car battery.
What is TCM transmission control Module?
What is a Transmission Control Module? The TCM is an electronic mechanism that collects data from the transmission, interprets signals sent from other parts of the vehicle (i.e. throttle position sensor, turbine speed sensor, fluid temperature sensor, etc.), and helps to regulate the gears shifting.
Where is the TCM relay located?
A transmission relay is usually located in the power distribution box under the hood on the driver’s side of the vehicle.
What does a TCM relay do?
The TCM power relay control circuit exists between the battery and the transmission control module, and protects the transmission’s computer from voltage irregularities. It also allows for a self test when the ignition key is turned on.
When to replace a Transmission Control Module ( TCM )?
Rather than relying on hydraulic or mechanical control over a transmission system, newer vehicles use a transmission control module instead. A car’s TCM will likely never need replacing, but if you have a bad transmission control module, immediate replacement (or repair) will be necessary.
Where is the TCM located in a car?
