no cause when i was at rosedale we did 4.10's in my teachers mach1 it had automatic trans in it and it destroyed the tranny, he got to 6,000 miles and started losing gears. it started with overdrive then 3rd, then 2nd and i have also read in the one MM&FF that if u dont retune the p.c.m it messes everything up. the article was done on project milf i cant remeber what issue it was but i have it.![]()
