I am working on a T50E. The truck doesnt move in forward or reverse. The fuses are all ok , and I have a spare directional lever that I plugged in and still nothing. When I move the directional lever I feel the solenoids are getting the signal but I was wondering if maybe they might be going bad. They didnt have much magnetic pull when i checked them. The u-joint is fine. I have a maintenace and parts book but they are vague.The only other thing I can think of is put a gauge on it. Anyone think of anything else to try?
