Well Installed the TT3000 last week and after driving around for a week just to get used to it, it still sucks. I know i need a shift kit b/c the shifts are really poor now. The problem is that when I shift into 3rd gear at WOT the converter seems to lock then unlock per the RPMS. The tach jumps a couple hundred or so RPMs then falls back, then jumps back up, then falls back.. Its really irritating b/c i love top end. Now i dont even like getting on it b/c of this problem.. Anyone have any ideas. whatever it takes to fix this i will do it. Of the guys i have talked to that have the same converter have not had this problem.

TTT sounds like the problem I'm having ... converter should never lock WOT unless you specifically program it to... mine's doing this same thing... hits 3rd gear, holds RPM and then suddenly "unlocks" and RPMs shoot up
