I run a trans-go shift kit in my 1971 727. Had it now for 9 years. Manually shift all the time. Shifts as good today as it did 9 years ago.




That kit addresses some of the issues that cause wear in a stocker.

PS, if it's so hard on the transmission, why did Ma Morpar make it possible to manually shift from low to drive, and drive to low?




The intent of being able to manually shift and hold certain gears is to delay shifting on a hard pull and/or for compression braking in the hills.

Back when I was a kid, we manually shifted them things all the time. I don't remember anyone having transmission troubles.




Again, it's about "occasional" versus "frequent".
