I have a TH 350 that I bought Used from the wrecking yard, recharged core, and fresh paint on outside, paid $900 bucks, oh, and also 2nd stage shift kit...

Now, I originally purchased a TCI SSF 700R4 with the High Stall TC to go with...paid cash, close to $5000, day I drove it home, leaked....

GM dealership installed it, TCI washes its hands of it, I am stuck with it....

I am pissed that nobody really stands behind with they sell.

This tranny was pulled and taken apart, put back together, reinstalled, and now is leaking again, less than 1000 miles this time.

TCI has pissed me off, GMC has pissed me off.

the Raptor Tranny would have been a better choice, made by a different manufactuer, and I would never go to GMC ever again for any kind of work on any of my vehicles, and I am even considering changing brands, even though I have been loyal to GM all of my working Life....
