Is Your GM Vehicle’s Transmission Acting Unpredictably?
Experiencing harsh, delayed, or erratic shifts in your 2005 Buick Rainier or other compatible GM vehicle can be incredibly frustrating and concerning. A flashing check engine light and a transmission that seems to have a mind of its own are classic signs of a failing Transmission Control Module (TCM). Ignoring these symptoms can lead to further transmission damage and leave you stranded. It’s time to restore the crisp, reliable performance you expect from your vehicle with a solution designed for a perfect fit and function.
Common Symptoms & Your Direct Solution
A faulty TCM can manifest in various ways, often triggering diagnostic trouble codes (DTCs) like P0700, P0740, P0753, P0758, or P1860. You might notice the transmission getting stuck in one gear, failing to shift, or causing a significant drop in fuel economy. Our pre-programmed TCM is the definitive solution to these issues.

Expert Insight: The Critical Role of VIN-Specific Programming
As a technician with over 20 years of experience, I’ve seen countless drivers waste time and money on generic modules. A modern vehicle’s transmission isn’t just a set of gears; it’s a complex system that relies on precise data from the engine, wheel speed sensors, and more. The TCM is the brain. Our VIN-matching process ensures that the module we send you has the exact software DNA your vehicle was born with, but updated for today’s standards. This prevents communication conflicts and guarantees the transmission operates exactly as the GM engineers intended, providing a reliable, long-term fix.
Don’t let a faulty TCM dictate your driving experience. This is your opportunity to fix the problem correctly the first time. By installing our Programmed 2005 Rainier Transmission Control Module, you are not just replacing a part; you are restoring your vehicle’s reliability and your confidence on the road.
Frequently Asked Questions
Do I need to take this part to a dealer for programming?
Absolutely not. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it to you. This makes it a true plug-and-play installation, with no additional programming or dealer visits required.
How do I provide you with my VIN?
After you complete your purchase, you will need to send us a message with 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.
Where is the TCM located on my 2005 vehicle?
The location can vary slightly by model. Common locations for these vehicles include the LH (driver’s side) engine compartment, inside or beneath the air cleaner housing, or behind the LH strut tower. Please consult a repair manual for your specific model to confirm the exact location before beginning installation.
Is this compatible with other part numbers?
Yes. This module is a direct replacement for a range of part numbers, including 24223112, 24226863, 24233595, 24239427, YBWW, YDFC, YDFD, YDLT, YJHY, YKTB, and YKTF. If your original module has one of these numbers, this part will work for you.
What if this doesn’t fix my problem?
This Programmed 2005 Rainier Transmission Control Module is a guaranteed fix for a faulty TCM. However, transmission problems can be complex. We always recommend a proper diagnosis by a qualified mechanic to confirm the TCM is the source of your issue before ordering. Other potential issues could be related to wiring, solenoids, or internal mechanical components.
