I just put in a lvl2 performabuilt tranny, 3400 billet converter, and man was it a big difference! Shifts so much crisper and stronger. I can tell that it's handling the power and not getting over powered! I went to the track to see if I had gained anything. Only thing I gained was a traction problem, I tried ttaking off from 3400, 3000, 2000, 1500, 1200, and idle. If I lay on it hard at all right away I spin all the way threw to second and finally catch some Traction after I'm almost half way threw second. I took off nice and easy laying in to it after I got moving and it took off alot better. I think it's time for some slicks!
