This kit recalibrates your automatic transmission for optimum performance, extended life by eliminating shift overlap and excess wear on clutches & bands due to slippage.

Street/Strip is for high performance street use or for competitive events for the enthusiast who wants the hardest hitting, quickest possible shifts.
