This Performance Valvebody kit deals with the following problems:
- Inadequate pressure rise
- Burned clutches and bands
- Erratic shift points
- Soft or bump up shifts
- Bump on coast down shifts
- Raises lock up speed
- 2nd and 3rd flare up
- Part throttle searching between 4th and 3rd

The Superior 700-R4 performance valvebody kit contains an anti-stick throttle valve spring. This package deals with the weak 3-4 clutch problems in a very effective manner. The feed to the clutch is made more direct. Throttle valve travel is changed to stop slipping on very light acceleration. Timing is corrected on the 3-2 downshift and overall apply pressure and oil flow is increased.
