We provide the definitive solution: a professionally programmed Transmission Control Module (TCM) that restores the crisp, decisive shifting your GTO was designed to deliver.
Common GTO Transmission Problems & Your Direct-Fit Solution
If you’re experiencing any of the following symptoms, a failing TCM is the most likely culprit:
- Harsh or erratic 1-2 or 2-3 shifts

Frequently Asked Questions
Do I need to program this module?
No. This is the primary benefit of our service. The TCM will arrive at your door already programmed to the specific VIN you provide, making it ready for immediate installation.
Where is the TCM located on my 2005 GTO?
On the 2005 Pontiac GTO, the Transmission Control Module is typically located on the left-hand (driver’s side) frame rail in the engine compartment. Always consult a service manual for your specific vehicle to confirm the location before beginning work.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or reply to your order confirmation email. We cannot ship the part until we receive your VIN, as the programming is essential.
Will this fix my specific shifting problem?
This module is the solution for a very wide range of electronic transmission faults. If your GTO is experiencing issues like harsh shifts, delayed engagement, or specific transmission-related error codes, a faulty TCM is the most common cause. However, we always recommend proper vehicle diagnostics to rule out mechanical issues or faulty wiring.
What if my original part number isn’t 24234189?
This module is a direct replacement for many part numbers, including 24223112, 24226863, 24233595, 24239427, and others listed. As long as your vehicle is a compatible model listed and you provide the correct VIN, this unit will be programmed to function perfectly in place of your original.
Is any other ‘relearn’ procedure needed after installation?
While the unit is pre-programmed, some vehicles benefit from a simple throttle body relearn or a short period of adaptive driving for the transmission to fine-tune its shift strategy. In most cases, however, you will notice a significant improvement immediately after installation.
