This C2 C3 C4 C5 Corvette 1968-2004 Auto Transmission Shift Improvement Kit has all the features in the Shift Improvement Kit plus it provides the driver with manual control of their Corvette's automatic transmission.
Most stock automatic transmissions won't downshift into low gear above 15 mph, and automatically up-shift at a predetermined speed no matter what gear you're in.
With this kit, you can downshift at any speed, and you can hold the transmission in first gear to any speed that you want! This is an asset when your Corvette has got a modified engine and you want additional RPMs.
Available for:
- 1965-1974 C2/C3 Corvettes w/TH400 Transmission
- 1984-1993 C4 Corvette
- 1993-1996 C4 Corvette
- 1997-2004 C5 Corvette
