Is your 2006 Chevrolet TrailBlazer EXT suffering from frustrating and unpredictable transmission issues? If you’re experiencing harsh shifting, delayed gear engagement, or a check engine light that just won’t go away, a failing Transmission Control Module (TCM) is the most likely culprit.

This T42 TCM, service number 24252114, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a simple, direct-fit installation that gets you back on the road with confidence.
Common Symptoms & Your Solution
A faulty TCM can manifest in several ways, turning your daily drive into a stressful experience. This module is engineered to resolve these exact problems. If you notice any of the following, it’s time for a replacement:
- Harsh or Erratic Shifting: Abrupt, jerky gear changes or a feeling of the transmission slipping between gears.
- Limp Mode Activation: The vehicle gets stuck in a single gear (usually 2nd or 3rd) to prevent further damage.
- Warning Lights: A persistent Check Engine Light or Transmission Warning Light on your dashboard.
- Diagnostic Trouble Codes (DTCs): Common codes like P0700, P0750, or other solenoid-related faults point directly to a TCM issue.
- No Shifting: Complete failure to upshift or downshift, leading to poor acceleration and terrible fuel economy.

Frequently Asked Questions
What does a Transmission Control Module (TCM) do?
The TCM is a computer that acts as the brain for your automatic transmission. It collects data from various sensors on the engine and transmission to control shift timing, gear selection, and torque converter operation, ensuring optimal performance and fuel efficiency.
Is this part difficult to install on my 2006 TrailBlazer EXT?
Installation is straightforward for a DIYer with basic tools. On the 2006 TrailBlazer EXT, the TCM is typically located in the engine compartment on the left-hand (driver’s) side. The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. Because our 2006 TrailBlazer EXT transmission control module comes pre-programmed, no further steps are needed.
Do I need to take my vehicle to a dealer after installation?
No. The primary benefit of our service is that the module arrives fully programmed to your vehicle’s VIN. This eliminates the need for any post-installation programming or calibration, saving you time and a significant amount of money.
What happens if I don’t replace a failing TCM?
Ignoring a failing TCM can lead to more severe and costly transmission damage. Continued harsh shifting and slipping can cause excessive wear on internal components like clutches and bands, potentially leading to a complete transmission failure that requires a full rebuild or replacement.
