Duramax Tuner 6 Speed Conversion Kit

The Duramax Tuner 6 Speed Conversion Kit will help take some of the wear and tear off the engine in your 2001-2005 GM 6.6L Duramax. By adding a gear, there will be a 14% RPM reduction that will keep the revs at the most efficient part of the RPM range. The added bump in fuel economy will be most noticeable for those who go on long highway commutes.

This 6 Speed Conversion comes with Duramax Tuner’s transmission tuning that will improve the reliability by calibrating the shift firmness and timing. You’ll feel the smoothness and better shift quality and quieter your ride will be when adding this kit. By drastically decreasing NVH (Noise, vibration, and harshness), this conversion kit will  give you a much better ride.
