Is Your Chevy HHR Shifting Erratically?
If your 2006-2011 Chevrolet HHR is suffering from harsh, delayed, or unpredictable shifting, getting stuck in gear, or has the check engine light on with transmission codes, you’re not alone.

Expert Insight: Why VIN Programming is Non-Negotiable
Many sellers offer generic, un-programmed modules, but this is a recipe for failure. A Transmission Control Module is not a one-size-fits-all part. Your HHR has unique factory settings for its specific engine, tire size, and gear ratios. Our VIN programming process installs the latest GM software updates tailored specifically for your vehicle. This ensures not only that the part works, but that it performs optimally, preventing the very same shifting problems and error codes you’re trying to fix. Installing our correctly programmed 2006-2011 Chevy HHR transmission control module is the difference between a quick fix and a lasting solution.
Frequently Asked Questions
What does a Transmission Control Module (TCM) do?
The TCM acts as the brain for your automatic transmission. It collects data from various sensors in the engine and transmission to control shift solenoids, regulate fluid pressure, and ensure smooth, timely gear changes for optimal performance and fuel economy.
Why is VIN programming so important?
VIN programming loads your vehicle’s specific software and calibration files onto the module. Without it, the TCM cannot communicate correctly with your vehicle’s engine computer and other systems, leading to poor performance, error codes, and potential damage to the transmission. Our pre-programming service makes this a true plug-and-play part.
Is this part difficult to install?
For the Chevy HHR, the TCM is typically located in the engine compartment on the driver’s side, making it relatively accessible. Installation usually takes under 30 minutes for someone with basic mechanical skills. Simply disconnect the battery, unbolt the old module, unplug the connectors, and install the new one in its place.
Will this fix my P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause, it’s essential to diagnose any other codes that appear alongside it. Replacing a faulty TCM is a very common fix for a P0700 code paired with other transmission-specific faults.
Do I need to send my old part back?
No. We do not require a core return. You can keep or dispose of your old module, saving you the time and expense of shipping it back.
What happens if I don’t replace a bad TCM?
Continuing to drive with a failing 2006-2011 Chevy HHR transmission control module can lead to progressively worse shifting, poor fuel economy, and eventually, severe mechanical damage to your transmission, which can result in a much more expensive repair.
