Can a car run without a TCM?
Without a properly working module, your car would be unable to change gears when needed, which could ultimately lead to not only a subpar driving experience but also serious mechanical issues that require expensive repairs.
Do I have to program my TCM?
When you install a new TCM in these vehicles, it must be programmed with dealer-level equipment or equivalent, and the programming must be performed on the vehicle. What’s more, you should never try to drive the vehicle to the dealership after the repair; it may cause premature transmission failure.
How do you know if your TCM is bad?
Some common signs of a bad transmission control module include:
- Unpredictable shifting.
- Trouble shifting into higher gear.
- Trouble downshifting.
- Getting stuck in the same gear.
- Poor fuel economy.
- Check engine light comes on.
Can a TCM be reset?
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.
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.
Are there any codes stored in the TCM?
So there must of been codes stored in the TCM. Throwing parts at it because some code reader gave a code is such a waste of money. There are so many different ways a transmission can fail.
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.
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.
