TCI Trans-Scat Kit 1997-06 GM 4L80E

TCI Trans-Scat Valve Body Kits are designed to prevent transmission slippage and lag and to produce a solid shift that is suitable for towing applications. These valve body kits also deliver a competition quality gear shift, allowing you to downshift the vehicle on demand. Most models allow you to manually shift and hold the transmission in first gear until you shift to a higher gear. This process is very advantageous when extra power is needed to top a hill. While the vehicle remains in drive, it will still be fully automatic. This kit vastly improves the second and third gear shift, improves performance, fuel economy and helps extend clutch and band life.
