Product Description
Fits: TH350 / 350C / TH250
Shift correction package for the GM Turbo 350 (TH350), with regular, heavy duty and towing applications in one kit. It services TH350 and TH250 lock-up and non-lockup units and contains parts to convert a 350 lock-up back to a 350 non-lockup (350C to 350) if wanted.
What it fixes
It helps address erratic passing gear, premature clutch and band failure, erratic shift points and weak shifts. The kit shows a lube modification for heavy duty units to prevent loss of converter lube under heavy throttle.
A high performance version (K350-HP) for street rods and racing allows manual low upshifting at any speed as well as automatic control, with super positive shifts.

Just what I needed
I ask'd the sales man for a kit that didn't give "neck snap'n" shifts, but a good firm shift. He recommended this. I haven't built the tranny yet but this is the 2nd tranny rebuild I have used Global. They have been super helpful and their shipp'n is fast as well on top of great prices. Ifn they'd just throw in a T-shirt and some stickers. Hint Hint,,,,, ;)
