Frequently Asked Questions
Do I need to have a dealership program this module?
No. This module comes fully pre-programmed to your vehicle’s specific VIN. It is ready for installation right out of the box, with no additional programming or dealer visits required.
Where is the TCM located on my 2006-2011 Chevy HHR?
For the Chevrolet HHR models from 2006 to 2011, the Transmission Control Module is typically found in the left-hand (driver’s side) engine compartment.
What tools are needed for installation?
Installation typically requires only basic hand tools, such as a socket set and ratchet, to remove the mounting bolts and disconnect the electrical connectors. We recommend disconnecting the battery before starting the repair.
Will this fix a P0700 trouble code?
Yes. A P0700 code is a general transmission fault code that indicates the TCM has detected a problem. Replacing a faulty TCM is often the correct solution to clear this and other related transmission codes.
What happens if I don’t replace a failing TCM?
Continuing to drive with a bad TCM can lead to worsening shifting problems, poor fuel economy, and potentially cause excessive wear or damage to internal transmission components over time, leading to much more expensive repairs.
Is there a core charge for this part?
No, there is absolutely no core charge. You can keep your old part without any extra fees or the hassle of returning it.
