Codes?

Seat switch working?
Park brake working? Both releasing and holding?
Range shifter working?

throwing code 2short and 2long ( fwd rev proportional solenoid) and code short long long short engine speed sensor . Ive tryed the forced calibration and i get threw the fwd and rev pedals, inching lever, and throttle position pot, then it throws the code for engine speed sensor and fwd and rev proportional solenoid

seat switches and working, park brake i assume is working because light comes on and then off when released, range shifter appears to be working?

Do you have charge pressure on the transmission?

 

[chevy791979]

If you can see it this is the theory and op of the charge pump

Tested at high idle you should have 200-220 psi at the plug on the filter housing

I have not checked that but i can. Tractor was working 100%, unloaded from trailer went to move forward and had nothing. Backhoe and loader operating 100% still.

Test it with a known good mechanical gauge. When shifting you should be short drop in psi as it fills the clutch pack.
