i bought a tci sizzler 727 years back and it was bad. but they had good customer service and sent me a new one. it failed a few years later (behind a stock 318 in a b body) so bought a book and rebuilt it my self! wasnt that hard at all. i thought about rebuilding a few to sell but i hate tranny fluid! good luck (verns on C st in tacoma wa will rebuild them for 250 - 500 depending on hard parts)
