Expert Insight from Our Technicians:
“As a veteran technician, I’ve seen countless drivers replace a TCM only to find the car still won’t work. Why? Because the module is the ‘brain’ of the transmission, and it must be programmed to speak the same language as your vehicle’s specific engine and options. We handle this critical step for you. By programming the module to your VIN *before* it ships, we eliminate the most common point of failure in this repair, saving you time, money, and the headache of a tow to the dealership.”
Frequently Asked Questions
Do I need to do any programming myself?
Absolutely not. This is the main benefit of our service. You provide your VIN during checkout, and we program the 2005 GM Programmed Transmission Control Module with the latest GM software for your specific vehicle. It arrives ready for a straightforward installation.
How do I provide my VIN?
After placing your order, you will receive clear instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We must receive and validate your VIN before we can program and ship your part.
Will this fix my specific transmission problem?
This TCM is a common and effective solution for issues like erratic shifting, failure to shift, and specific communication or solenoid error codes. While it resolves the vast majority of electronic transmission faults, we always recommend a proper diagnosis by a qualified mechanic to confirm the TCM is the root cause of your issue.
Is this a direct replacement for my original part?
Yes. This module is designed to replace the original factory TCM and is compatible with all part numbers listed, including 24223112, 24234189, 24239427, and YKTF.
What is the installation process like?
The TCM is typically located in the engine bay (e.g., under the air cleaner housing or on the LH frame rail, depending on your model). Installation involves disconnecting the battery, unplugging the electrical connectors from the old TCM, unbolting it, and then installing the new one in the reverse order. While it’s a straightforward process for many DIY-ers, we recommend consulting a service manual for your specific vehicle for precise location and instructions.
