Product Features:
- Fits 1967-1969 Mustangs with a C4 Transmission
- Simple, No Hassle Installation
- Faster, Improved Shifts

Stock automatic transmissions will experience crisp shifts after installation of the shift kit. Shift overlap and excessive wear on clutches and bands due to slippage is eliminated. Also, you are able to select the mode that best suits your application.

Stage 1 mode provides you with heavy duty operation. Gain firm, positive shifts without loss of driver comfort. This improves performance in all street vehicles and is recommended for regular passenger vehicles. However, you can step it up a notch with Stage 2 mode which is great for a street/strip car. This provides positive shifts for high performance street use or for competitive events. B&M created this second level for the enthusiast who wants the hardest, quickest possible shift.
