Transmission Relearning
The Allison transmission is a “Smart” transmission. That means that it pays
attention to how smoothly the transmission is changing gears, and modifies
the shifting to improve drivability. When the motor delivers more power (by
adding the Juice module), the transmission has to ‘re-learn’ how to shift.
After first installing the Juice module, you may notice rough shifting. The
best way to re-teach the transmission is to set the truck in the power level
you will be using most of the time. Then set out to drive, some city, some
highway, varying the driving and the speed. Make sure that you shift
through each gear 20 to 30 times. A good rule of thumb would be 100 to
200 miles. Remember that the truck must go through each gear 20 to 30
times. You will notice the shifting becoming better, and your truck
responding better to the additional power as you go through the learning
cycle.
