Frequently Asked Questions
What is VIN programming and why is it important?
VIN programming is the process of loading your vehicle’s unique factory software and calibrations onto the new TCM. This is crucial because it ensures the module works perfectly with your specific engine, tire size, and other options. It allows for a true plug-and-play installation without needing a dealership visit.
Is this module difficult to install?
For someone with basic mechanical skills, the installation is straightforward. On the 2006 TrailBlazer EXT, the TCM is typically located in the LH (driver’s side) engine compartment. The process involves disconnecting the battery, unplugging the old module’s electrical connectors, swapping the units, and reconnecting everything. It usually takes under 30 minutes.
Will this fix a P0700 trouble code?
A P0700 code is a general transmission fault request from the TCM to the ECM to turn on the check engine light. While this module often resolves the underlying issue causing the P0700, it’s important to have the specific transmission codes (e.g., P0751, P0756) read to confirm the fault is related to the module or solenoids it controls. This 2006 TrailBlazer EXT T42 TCM is a common fix for these electronic faults.

No, there is no core charge or requirement to send your old module back to us. You can keep it or dispose of it at your convenience.
