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 to find a bad Transmission Control Module?
Sometimes it’s found under the center console in the interior or even under the hood near the battery or inner fender panel. If you ever have a problem with your transmission control module, you’ll need to have it inspected right away. A bad TCM will spell trouble for your vehicle and your ability to drive it.
How much does it cost to replace a TCM?
You can expect the parts costs to be around $450 to $700 while the labor costs will be around $50 to $200. Of course, you can order a new TCM online and ask a mechanic what their hourly labor rates are. However, most of the cost for this replacement job goes toward the parts cost itself and it can vary greatly by car manufacturer.

What to do if your ECM is not working?
If your car seems to run fine but the Check Engine light won’t turn off, your ECM may be at fault. The only way to be sure is to visit a mechanic with the proper computer. They can analyze your vehicle’s error codes, and let you know exactly what the problem is.
How does the ECM work in a car?
Your car’s Engine Control Module (ECM) monitors all the sensors in the vehicle to make sure that the car’s systems are running as they’re supposed to. When conditions change, the ECM will automatically make adjustments in real time. That is why it is so important to recognize the symptoms of ECM failure.
Why does my ECM log an error code?
When an issue arises, the ECM will log an error code that lets you know the source of the problem. This can be advantageous since you can determine the exact cause of failure. It can also be inconvenient since you’ll need a mechanic with an expensive computer to read the error code.
