What is a Transmission Control Module

At Zarin Truck & Automotive in South Heights, we understand the importance of keeping up with and understanding the latest in automotive technology. Gone are the days when fluids and vacuum lines were all that controlled the function of your engine and transmission, and we’ve moved into an era where computer control reigns supreme.

While there are countless benefits to computer-controlled automotive systems, there are also many ways for these systems to fail. When they do, sometimes the symptoms don’t make the issue immediately obvious, and a Transmission Control Module is one such component.

The TCM does what the name states; it controls the transmission. Shift points and the act of shifting itself are controlled by this module, meaning without it, the transmission is essentially one giant paperweight. A TCM is a reliable component...however, it is comprised of many intricate parts, and if one of them fails, the transmission may behave strangely. Your car, truck, or SUV may not shift when it’s supposed to, may shift hard, may shift erratically, or may not shift at all. Typically these conditions are accompanied by a warning light on your dash, but not always.

If your transmission is misbehaving, have one of our mechanics take a look. Whether it’s the TCM or some other issue, our professional technicians will have your issue diagnosed and corrected in no time.
