Frequently Asked Questions
What does a Transmission Control Module do?
The TCM acts as the “brain” of your automatic transmission. It receives data from various sensors on the engine and transmission to control when the gears shift, how firmly they engage, and when the torque converter locks up, ensuring optimal performance and fuel efficiency.
Is this TCM difficult to install on my HHR?
Installation is straightforward for a DIYer with basic tools or any professional mechanic. On the 2006-2011 HHR, the TCM is typically located in the engine compartment on the driver’s side. The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. The entire job usually takes less than 30 minutes.
Will this module fix my P0700 error code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the underlying cause of a P0700, it’s important to have the specific secondary codes read (e.g., P0751, P0756) to confirm the issue is with the module or solenoids it controls. In many cases, a faulty TCM is the culprit.
Do I need to send my old part back?
No. We do not require a core return for this part. You can keep or dispose of your old module without any additional core charges or hassle.
How do I ensure this is the exact part for my vehicle?
This 2006-2011 HHR Transmission Control Module is guaranteed to be the correct fit for your vehicle. During checkout, we will ask for your vehicle’s VIN to ensure we program the unit with the exact software for your specific configuration, guaranteeing compatibility.
