How it works

The kit contains the parts to convert a TH350 lock-up back to a 350 non-lock-up. A lube modification for heavy duty units, shown in the kit, prevents loss of converter lube under heavy throttle.

Corrects erratic passing gear, premature clutch failure, premature band failure, erratic shift points and weak shifts.
