Can you help me diagnose 2013 JD X758 400 hours transaxle problem ? I was mowing and PTO disengaged then it would no longer go forward and reverse. I was about a quart low on fluid. I bought the tractor used and have not had the chance to change fluid everything was working so I put the tractor to use. 2 days after the problem I changed the fluid and filter. Forward and reverse is interment and still can not get pto to come on. For the the forward and reverse I was thinking replace directional control valves, they are able to depress but still not getting forward or reverse. The linkage moves and does not seem to be the problem To fix the pto I was going to replace the solenoid . If that does not work I am thinking charge pump. I do not think the pto is electrical because the seat switch and break switch work plus I get the light on dash so to me the circuit is complete. I would like your opinion on the matter.
