Any one knows what causes that? thank you It is normal for a 727(and probally a 904) for the driveshaft to turn harder in reverse than foward, I think it's that way. My trans. with a low Mopar brand low(2.77) gear set is harder to turn backwards than my standard low(2.45) gear trans is It is also harder to push the car backwards with the low gear trans. in it Mr.Cab Racing and winning with Mopars since 1964.

All the 727 that I had before feel the same way as my car does, but the one I built for my friend does not feel that way. The car is easy to push back and it raced last week and went 9.70 so I figured that if I could find the problem and fix it, then I could gain a couple tenths on mine. so thank you for the info, I know better know
