need trans help! completely lost on this one.

You built it, not TCI.
Parts are pretty much all same except if you get upgraded stuff.
TCI's problems are with thier builders lack of ability or management not allowing the builders to do it right every time.
Pretty much everthing I've seen posted about them that the end result was explained was because of a shortcut or inexperience.
Then they screw ya on the warantee somehow by blaming it on something like not using thier own in house converter.




Why stay away from the TCI stuff??
I used a TCI kit in a 727 in a 79 Dodge Power Wagon 4x4 mud drag truck with a 550 hp 440 that I built for a friend. The truck would roast all 4 tires on the road and held up 4-5 races a year plus daily driving for 6 years until the day he sold it (to help build his 71 Cuda)...after that I don't know.
