Expert Insight: Why Pre-Programming is Non-Negotiable
As a technician, I’ve seen countless vehicle owners try to save a few dollars by installing a used, non-programmed TCM. The result is always the same: the vehicle won’t start, won’t shift correctly, or displays even more error codes. That’s because the TCM is the ‘brain’ of your transmission and must be perfectly synced with your vehicle’s engine computer and security system. Our process handles this critical step for you, ensuring the programmed 24226863 TCM you receive communicates flawlessly with your vehicle from the moment it’s installed.
