Take your '01-'05 Allison to another level by adding a sixth gear! Improve your LB7 or LLY's reliability by utilizing Duramaxtuner's in-house designed and tested kit coupled with their established transmission tuning. Duramaxtuner calibrates the firmness and timing of shifts, so you’ll be guaranteed to feel the smoothness and better shift quality missing on the 5 speed Allison. If you’re using your truck as your daily driver, the added gear helps take the wear and tear off your engine while cruising at high speeds. It keeps your RPMs at the most efficient curve of the rev range, giving it the best ride possible!
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 the highway. You’ll also notice how much quieter your ride will be when adding this kit to your truck. Noise, vibration, and harshness will decrease drastically, giving you a much more enjoyable ride.
