My 900 hr NH T5060 just started throwing this code.  It only starts happening after an hour or more in the field.  When it happens, the tractor stops and the "STOP" light flashes.  The error code says it is a 12V short to ground in one of the transmission solenoids.  There are two that match the description, side by side under the tractor.  I bought one and changed it out thinking I had a 50/50 shot of solving.   It started again, so while in the hay field I swapped the one I had taken out with the remaining solenoid thinking there was no way both were bad... wrong again.  It started doing again almost immediately. 

 

If I shut down the tractor for a few minutes (anywhere from 2 to 10) it will reset and work again for a while.  It somehow seems to be temperature related, at least the temperature of the transmission.   

 

Anybody have any ideas?  

 

Thanks,

 

KH

Assuming the codes are pointing to the right component(s) and knowing that you changed both of them I would lean toward the wiring to/from the components.

One of the hardest things to find is a wire that is pulling apart or breaking down when things heat up. They will ring out when tested for continuity but you have to read the ohms to know if a wire is breaking down. A failing wire will have more resistance when compared to a known good wire of the same gauge and length.

I know little about tractors, but your code is for the dump valve.  The only line drawing I saw on it was one with three solenoids grouped together, forward, reverse, and dump.  Two solenoids together sounds like FWD And PTO, but like I said, I know next to nothing about them.

Had this happen just a couple weeks ago on my T5040.  Exactly the same code, exactly the same symptoms. They came out an changed the solenoid (called it a dump solenoid). There is 3 on my tractor located together under the left side right next to the fuel tank. Mine was the front one. The mechanic said it appeared to be breaking down as it was leaking fluid around the plug They said a wire was being pinched by a fuel tank bracket also but I don't think that was the problem. Hope this helps.

Just FYI, it was the dump valve solenoid.  No visible damage, and it tested properly at room temperature, but when it got hot it failed.

Changed it out and no problems.

 

Thanks for the info.
