How does the TCM communicate with the modules?
The TCM communicates with these modules over the controller area network (CAN) bus. CAN is a two-wire bus, consisting of the CAN High and CAN Low lines. There are two terminating resistors, one at each end of the CAN bus.
What should I do if my TCM is not working?
If the TCM doesn’t respond to the scan tool, the next step is to figure out why. Like any other electrical device, the TCM circuit must have proper power and ground. TCM circuit integrity can be checked with a DMM. If a problem is found, the factory wiring diagram will need to be traced and the circuit repaired.
What does it mean when your TCM says u0101?
Code U0101 indicates the TCM is not receiving or transmitting messages on the CAN bus. Code U0101 is typically caused by one of the following: Sometimes U0101 can pop up intermittently, or it can result from a dead battery. This is especially true if the code is a history code and not current.
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?
While swapping out a box might seem simple, the TCM is located inside the transmission in many modern cars, trucks, and SUVs. Opening the transmission is a laborious task, which is why it is reasonable to expect labor costs of at least $300 to replace the transmission control module.

What does a Transmission Control Module ( TCM ) do?
Your vehicle’s transmission control module (TCM) is like a tiny computer. It has the important job of interpreting electrical sensor output of components in an engine with an automatic transmission . What is a Transmission Control Module?
