An Expert’s Note on VIN Programming
In modern vehicles, the TCM doesn’t just control the transmission; it constantly communicates with the Engine Control Module (ECM), Anti-lock Brake System (ABS), and other systems. Using a generic, non-programmed module can lead to communication conflicts, persistent error codes, and even incorrect shift patterns. By programming this 2005 Buick LaCrosse TCM 24239427 to your exact VIN, we ensure it has the correct software and calibration files to integrate perfectly with your car’s unique electronic ecosystem. This is the crucial step that guarantees a successful and lasting repair.

How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will contact you with instructions, or you can message us directly with the information.

Is any other procedure needed after installation?
While the module is plug-and-drive, it is best practice for your mechanic to perform a transmission fluid level check and a relearn procedure with a capable scan tool. This ensures the new module adapts perfectly to your transmission’s current state.
Will this fix a “No Communication” error with the TCM?
