I have an Eaton Fuller RTO16908LL behind a Cummins NTC 230 in an '80 Autocar. When I back up, I can't get it out of gear after I stop. Only way to take it out of reverse is to pull hard to the left, and pull back hard to the rear until it pops out. Transmission operates fine in forward gears.
Any suggestions on where the problem might lie?
Thanks
