This valve body kit deals with these problems:
* Late shifts
* Weak shifts
* Band failure
* Harsh downshifts
* Converter shudder
* Front seal problems.
A "Ben Law" accumulator check valve is supplied in the kit to give a much quicker release of the band when shifting into 3rd. This valve, combined with the servo return spring supplied in the kit, saves the band from premature failure.
2. A specially designed drain back valve installs into the cooler line to stop converter drainage. This is a "must" for older units.
3. The kit modifies early auxiliary valve bodies to eliminate lockup problems which are very common to these units.
