I have a Clark c30l serial# p232l 0638 9645k5 with transmission TA30MS. Operator said transmission locked up. I went and dip stick was dry. Serviced it and it would not go back into gear after idling and checking fluid level. When attempting to tow it out of the way it didn't move but an inch and something was bound up. Carried back to shop and with one wheel off the ground and it idling in neutral the wheel still wants to spin. Are solenoids not or partially activating as original cause?
