6L80E/6L90E - Transmission-Only Tune

The 6L80E is a robust six-speed automatic transmission commonly found in a range of vehicles, including trucks, SUVs, and sports cars. While it is known for its durability, it can benefit significantly from custom tuning.

We offer a transmission-only tune for the 6L80E transmissions that will improve shift quality, reduce torque converter failure rates, enhance towing and hauling, preserve transmission components, and potentially provide better fuel efficiency.
