We offer the definitive solution: a professionally programmed TCM, specifically matched to your vehicle’s VIN, ready for a straightforward installation.

Expert Insight: Why VIN-Specific Programming Matters
Many people assume a TCM from another 2005 Grand Prix will just work. That’s a common and costly mistake. GM built these cars with dozens of variations in engine size, axle ratios, and even tire sizes. The TCM’s software must match these specifics perfectly. Our VIN-programming service isn’t just a convenience; it’s a critical step. We ensure the software loaded onto your module is the exact version your car’s powertrain needs to operate in harmony. This prevents future shifting issues, incorrect speedometer readings, and potential damage to your transmission.
Don’t let a faulty module keep your car off the road. Ordering this programmed 2005 Grand Prix TCM is the most effective and efficient way to solve your transmission woes and get back to driving with confidence.
