Is Your Cadillac or Pontiac Plagued by Poor Shifting?
There’s nothing more frustrating than when the sophisticated performance of your vehicle is ruined by transmission problems. Harsh shifts, delayed engagement, or a sudden check engine light can turn a pleasurable drive into a stressful ordeal. If your Cadillac STS, CTS, SRX, Pontiac Solstice, or Saturn Sky is exhibiting these symptoms, a failing Transmission Control Module (TCM) is the most likely culprit. This isn’t just an inconvenience; it’s a core component failure that compromises your car’s reliability and performance. You need a solution that doesn’t just fix the problem, but restores the precise, confident driving experience you expect.
Common Symptoms & Your Solution
A faulty TCM can manifest in several ways, often triggering Diagnostic Trouble Codes (DTCs) and noticeable performance issues. If you’re experiencing any of the following, this part is your definitive solution:
- Erratic or harsh shifting between gears
- Vehicle stuck in one gear (limp mode)
- Failure to shift into or out of gear
- Illuminated Check Engine Light or Transmission Warning Light
- Common trouble codes such as P0700 (Transmission Control System Malfunction) or U0101 (Lost Communication with TCM)
Our expertly prepared programmed 24239785 TCM is the answer. We eliminate the guesswork and costly dealership visits by pre-flashing the module specifically for your vehicle.

Expert Insight: Why VIN Programming is Non-Negotiable
In modern vehicles like your Cadillac or Pontiac, the TCM isn’t just a simple controller; it’s a networked computer. It constantly communicates with the Engine Control Module (ECM), Anti-lock Brake System (ABS), and other systems. Simply installing a used or non-programmed module will cause a communication breakdown, leading to a no-start condition or persistent error codes. Our VIN-specific programming ensures the module has the correct software and security credentials to integrate seamlessly, just like the original part from the factory. This critical step is the difference between a lasting repair and a recurring nightmare.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically add it as a note during checkout or reply to your order confirmation email. We cannot ship your part until we receive your VIN.
Is any additional programming required after installation?
No. This programmed 24239785 TCM is a complete plug-and-play solution. Because we flash it with your vehicle’s specific VIN data, no further dealer programming or setup is necessary. In some cases, a transmission relearn procedure may be recommended, which can often be done without special tools.
How can I be sure this part fits my vehicle?
Please check the fitment list provided on this page. This module is a direct replacement for part numbers 24239785, 24235224, and YLMU. Providing your VIN allows us to perform a final verification, guaranteeing compatibility before we ship.
What tools are needed for installation?
Installation is typically straightforward for a moderately skilled DIYer or any professional mechanic. It usually involves basic hand tools like a socket set and ratchet to access and unbolt the old module. Always disconnect the battery before beginning work.
What if I have a transfer case issue instead of a transmission issue?
For certain models like the Cadillac STS, CTS, and SRX, this module also functions as the Transfer Case Control Module (TCCM). If you are experiencing issues with your all-wheel-drive system and have confirmed this part number, our programming will correctly configure it for transfer case operation based on your VIN.
