T40D Ser# 8EB12177 not going into forward or reverse. This happen all of a sudden while using it. It was working just fine before without any indication of any kind. It's engine runs great and the lift still works well. The transmission solenoids are getting power and the hand brake switch is grounded. I didn't pull apart the inching valve but there is 0 pressure or fluid at the lines going to it. I cracked them open a little to verify that. The first thing that I checked was the oil level for the transmission. It was way over filled while running. I'm coming to the conclusion that there is something wrong with the pump for the tranny. Not having a service or parts manual for this machine, I'm just winging it. Help would be appreciated. Thanks!
