Does a TCM have to be reprogrammed?
Re: Used TCM Need Reprogramming or Not? Short answer is NO. No programing is required if the new TCM came out of a working car of the same elk as yours.
What causes TCM to fail?
Damage to the control module can be caused by voltage overload, when there is a short in the solenoid or actuator circuit; when water causes the circuits to get shorted out; or vibration and thermal stress.
How do I reset my TCM?
To reset the TCM, I turn the key to the ON position, step on the accelerator pedal for 10 seconds, turn off the engine, release the accelerator pedal and wait 5 minutes for the engine to restart.
How much does it cost to reprogram a TCM?

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.
Why is my TCM not working on my 6L80E?
I have had issues with a TCM in a 6l80e, the gearbox stays in 3rd and I was getting invalid gears in the PRNDL Status in hptuners but no codes from the TCM. The TCM reads fine into hptuners though. I thought it could have been the plastic gear range selector in the gearbox but after replacing that I still had the issue.
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.
Can a TCM be exchanged for an ECM?
These TCMs communicate with the ECM Using a dual strand CAN BUS network. Both the ECM and TCM have operating systems unique to each year. 2006.5 and 2009 tend to be interchangeable, as well as 2010-2013, but they can’t be exchanged between this year gap.
