Title pretty much sums it up. 175,000 miles on the truck. Reverse is gone and I have to drive it with the OD off, otherwise, once it goes into OD, it's like it goes into neutral. Trans Fault is in the display and only one code is stored, P0732 trans gear #2 incorrect ratio. Any suggestions or is it time to rebuild it? I can live without OD but no reverse is a pain.
