FAQ

Q1: What are the symptoms of a failing transmission control unit?
You may experience harsh or delayed gear shifts, hesitation during acceleration, the transmission getting stuck in a single gear, or the appearance of transmission-related warning lights on the dashboard.

Q2: Does this unit need to be programmed after installation?
Yes. This is a critical component. After physical installation, the new unit must be professionally programmed or coded to your specific vehicle to ensure it communicates correctly with the engine and other systems and learns your driving style.

Q3: Is a new or remanufactured unit the better choice?
Both are viable options. A new unit offers the highest reliability. A remanufactured unit is a more sustainable and cost-effective alternative, as it has been fully disassembled, rebuilt with new wear parts, and rigorously tested to perform like a new unit.
