Is Your Buick Rendezvous Shifting Erratically?
There’s nothing more unsettling than a transmission that doesn’t behave predictably. If you’re experiencing harsh shifts, delayed gear engagement, or a sudden check engine light, a failing Transmission Control Module (TCM) is often the culprit. This critical component is the brain of your automatic transmission, and when it falters, it can make driving stressful and unsafe. It’s time to stop worrying about every stoplight and get a reliable solution that puts you back in control.
Common Symptoms & Your Direct-Fit Solution
A faulty TCM can manifest in several ways, often triggering Diagnostic Trouble Codes (DTCs) and frustrating driving issues. Look out for:
- Abrupt, jerky, or slamming shifts
- Transmission getting stuck in one gear (limp mode)
- Failure to shift into or out of gear
- Check Engine Light illuminated with transmission-related codes (e.g., P0700, P0751, P0756)
- Loss of communication with the scan tool

An Expert’s Note on VIN Programming
“Many people think they can just swap a used TCM from another vehicle. The problem is that the module is coded to the original car’s specific options, gear ratios, and tire size. A mismatch can cause even more shifting problems or prevent the vehicle from starting at all. Our VIN-programming service isn’t a convenience; it’s a necessity for a successful repair. We ensure the 2004-2005 Buick Rendezvous TCM you receive is a perfect digital match for your exact vehicle, making the installation process smooth and the result reliable.”

Frequently Asked Questions
Do I need to do any programming after I receive this part?
No. This module arrives 100% plug-and-play. We program it using the VIN you provide during checkout, so it is ready for installation right out of the box. You will not need to visit a dealer or mechanic for additional programming.
Where 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.
What is a TCM and what does it do?
The TCM, or Transmission Control Module, is a computer that controls your vehicle’s automatic transmission. It reads data from various sensors to determine the perfect time to shift gears for optimal performance, fuel economy, and smoothness.
Is this compatible with other part numbers?
Yes. This unit is a direct replacement for several part numbers, including 24223112, 24226863, 24233595, 24234189, and 24239427, among others listed in the description. As long as your vehicle is on the fitment list, this programmed module will work.
What if I still have issues after installation?
While this TCM is a common solution for many shifting problems, transmission issues can be complex. We recommend having the vehicle properly diagnosed by a qualified technician. Sometimes, a shifting problem can be caused by mechanical parts like solenoids or sensors, not just the computer.
What does the one-year replacement warranty cover?
This unit is backed by our one-year replacement warranty, which covers the module itself against defects in workmanship. Please contact us for full details and procedures should you need to make a claim.
