I have the electrical section working. I disassembled the OD unit. I found the lockout shaft binding in the OD case. I corrected the issue. Looking at the other components, they seemed to look good. However, after reassembling the trans and try to move the vehicle, it will move forward intermittantly. Reverse works fine and if i put the trans in lockout it will move in fwd and rev. I think the roller clutch assembly might be slipping. With the vehicle on the lift and trans in 1st gear. I can turn the driveshaft both ways. Sometimes it catches and locks and sometimes it doesen't. I assume if the roller clutch is bad, the vehicle will not move in any forward gear ? Thoughts?
Thanks
