Shift Kits and Shift Improvement Kits
What is a shift kit?
A shift kit is a set of automatic transmission components designed to improve how well your vehicle shifts between gears. A shift kit modifies the transmission's shift timing in order to dramatically increase shift firmness and durability of the transmission components. Accesspeed offers various levels of shift improvement kits, including Stage 1, Stage 2 and Stage 3 Shift Kits.
Does a shift kit improve performance?
Yes. A shift kit (or shift improvement kit) will firm-up the shifts in your automatic transmission by making them happen quicker, thus reducing clutch and band slippage. A good kit can help extend transmission life. Some shift kits can also change the rpm where the shifts happen, which also improves performance.
