Lee, so you had trouble with your TCI Streetfighter too? My Son bought one and also their torque converter from Summit and it fried after only 200 miles. The front pump went out and chewed up both the tranny and torque converter. TCI "graciously" agreed (?) to fix or replace them even though they were 9 months old (warranty is 90 days but it took a year to build the car) However, we had to pay freight both ways ($ 200). We also had to pull the engine and transmission, build a crate, and do the shipping.....all work that they did not cover.
They did send a new torque converter and a replacement transmission, but we will never do business with TCI again. I have seen post after post on various forums where people had multiple transmissions from them go out. We thought we bought a quality product and didn't cut corners, so it is very discouraging to end up with a crap transmission.
If you have to deal with TCI, talk to Andre' up there, he was the go to guy we dealt with.
Since you are under the gun, I would go to the local pick and pull wrecking yard and get one, usually about $ 150 or so.
