G-Force T-5

[bry]

I broke third gear, it had about three teeth sheared off on my tremec. My T-5's the shifting forks and first gear kept failing. I don't understand why. My car is pretty mild. Its a 87' LX coupe with a stock shortblock, AFR 185 heads, TFS intake(street heat),and a 150 shot of juice. I use a centerforce Dual friction,4.
10 gears on a moser spool, and BFG Drag Radials. My car only ways 2400LBS. I can't figure out why I have so many tranny problems. Any help is very welcome. Thanks.
