If you are talking about the FTI SB2800 I have the same one. If you are still on warranty try to return it because mine didnt have that fitment issue, it matched the flexplate perfectly. So your issue may very well be that the studs arent spaced correctly on the TC. What else is done to your engine? I just swapped in a PI engine with 262s, UD pulleys and long tubes with an SCT chip and mine stalls at 2900. Did you check the part number before putting it in? They have a 2400 stall (SB2400) and they look exactly the same and may have been boxed wrong. They have the number stamped into the converter itself. If its correct you might have gotten a bum TC to begin with. I had to pull my car back apart because the rear main leaks but it should be back together before next weekend (knock on wood).
