When I got to the point of putting the rod between the floor shifter and the arm on the tranny I wasn't sure if the part that had the adjustment on it went on the shifter part or the tranny arm. I have it on the shifter arm, any thoughts?

Now when I go from 1st to 2nd there seems to be no shift and the same into 3rd. This is with wheels of the ground on lift. There is a slight increase in speed from 1st to 2nd but only 4 or 5 MPH. Please help as I would like to take it out.

I've done GM TH350 and this will be my first mopar. Anything to look out for, or special tools I may need? I have the ATSG book.

The pic below shows a properly assembled sprag, if the position of the springs and rollers is reversed the sprag won't hold in Drive. 7124411-Sprag.jpg (37 downloads)

In manual 1st and reverse the band holds that drum, in drive only the roller clutch holds it so if you put the springs and rollers in wrong nothing is holding it in drive so you go nowhere. Don't rev it real hard trying to get it to go you will make things worse pull it back out and fix it, john is probably right I am not causing global warming, I am just trying to hold off a impending Ice Age!
