Frequently Asked Questions
Do I need to have this TCM programmed by a dealer?
No. This module comes pre-programmed to your vehicle’s specific VIN. Simply provide your VIN at checkout, and the unit will arrive ready for a plug-and-play installation, with no additional programming or dealer visits required.
Where is the TCM located on my 2006-2009 Trailblazer?
On the 2006-2009 Trailblazer (and related platforms like the Envoy and Saab 9-7X), the Transmission Control Module is typically located in the engine compartment on the driver’s side (LH).
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the underlying issue causing the P0700, it’s crucial to have the vehicle scanned for more specific codes (like P0750, etc.) to confirm the diagnosis. A faulty TCM is a very common cause.
Is this part difficult to install myself?
For someone with basic mechanical skills, the installation is straightforward. It involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. The entire process usually takes under 30 minutes.
What is the difference between a TCM and an ECU?
The ECU (Engine Control Unit) or ECM (Engine Control Module) manages engine functions like fuel, spark, and emissions. The TCM (Transmission Control Module) is a separate computer dedicated solely to managing the automatic transmission’s shifting and operation.
