An Expert’s Note on Programming
“Many people don’t realize that a new TCM is just a blank box. Installing it without programming is like putting a new computer in your car with no operating system. It simply won’t work. It has to be coded to your vehicle’s unique VIN to communicate with the Engine Control Module (ECM) and Body Control Module (BCM). Our process handles this critical step for you, saving you the time, expense, and hassle of getting your vehicle to a dealership. We ensure this Programmed 2005 Trailblazer EXT TCM works the first time.”

Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is essential for the programming process.
Will I need to do any extra programming after I install it?
No. The module arrives fully programmed to your vehicle’s specifications. The installation is a direct swap. In some cases, a transmission ‘re-learn’ procedure may be recommended, which can often be done by following a specific driving cycle or with a capable scan tool.
Where is the TCM located on a 2005 Trailblazer EXT?
On the 2005 Trailblazer EXT with the 8-cylinder engine, the Transmission Control Module is typically located in the engine compartment on the driver’s side (LH side).
Will this fix a mechanical transmission problem?
This part is designed to correct electronic failures within the TCM itself. It will not fix internal mechanical issues such as worn clutches, a bad valve body, or a faulty torque converter. We highly recommend a proper diagnosis by a qualified technician to confirm the TCM is the source of your problem.
Is this compatible with other part numbers?
Yes, this module is a direct replacement for multiple part numbers, including 24223112, 24226863, 24233595, 24234189, 24239427, YBWW, YDFC, YDFD, YDLT, YJHY, YKTB, and YKTF.
