Description

The Trans Go Performance 6L80-TOW&PRO is a reprogramming kit designed for 6L45, 6L50, 6L80, and 6L90 transmissions from 2006 onwards. This kit enhances shift performance for trucks and other performance applications, delivering quicker, cleaner, and firmer shifts with increased holding capacity. It maintains a factory shift feel at light to medium throttle while providing progressively firmer upshifts through wide-open throttle.
