2001 dodge ram no reverse after over haul

Customer Question

2001 dodge ram no reverse after over haul
Submitted: 1 year ago.

Hello and welcome to JustAnswer!
There are quite a few things that will cause a loss of reverse. If it does have all forward gears then you can rule out a clutch issue, which would leave a band related issue. The low/reverse band may not be adjusted correctly, there may be a servo issue, and I've seen striped spline between the rear annulus and overrunning clutch drum.
All forward gears work?

You have a plate next to the snap ring rather than the reaction plate?
Customer: replied 1 year ago.
which drum
Expert:  sprinkles08 replied 1 year ago.
We're discussing the rear clutch but the same applies for either.
Customer: replied 1 year ago.
just checked and they are in right
Expert:  sprinkles08 replied 1 year ago.
Pull the pistons back out to make sure the seals are in place and undamaged but I think you've at least transposed the discs between the front and rear clutches. They're different thicknesses, your front clearance is too large and rear is too small, which will happen if you put the discs in the wrong clutch.
Customer: replied 1 year ago.
