Description
Improve the reliability and performance of your transmission with the DuramaxTuner 6-speed Allison conversion kit specifically designed for the 2001-2005 LB7 & LLY Duramax trucks. The 6-speed conversion kit comes standard with custom TCM tuning that is designed for your specific truck to provide the best drivability possible, resulting in a significant improvement in smoothness and shift quality. The added 6th gear reduces wear and tear on the engine and it ensures that your RPMs are at the most efficient curve of the rev range for an even better driving experience.
In addition to helping keep your truck on the road longer, something you will notice is the added bump in fuel economy. This is especially true for those of us logging long commutes via highway. The less RPMs, the better your fuel economy. Picking up just a little bit goes a long way while putting on the commuting miles. You’ll also notice how much quieter your ride will be when adding our kit to your truck. NVH (Noise, vibration, and harshness) will decrease drastically, giving you a much more enjoyable ride.
CORE CHARGE
