Well I guess my trans didn't like the Mojave magnum (180.9). Cuzz it just locked up on me without warning. Has anybody used a T-56 magnum form Rockland gear. It's magnum has a better 5th & 6th ratio .84 & .67 (won't fall on it's face when I hit 6th) and good for 750 H.P. They can rebuild my old one & said that there were 2 torque/H.P ratings for the ZF. Should I try to fit T-56 or stay stock. The car has almost 100000 miles so I don't think it would hurt value & with the 4:10s should get me into the mid to upper 180's
