Any ideas on whats up on this?
Trans wants to run hot. With the radiator real clean can keep the motor temp down to 190. The trans doesn't shoot off the fault light when it gets to 230+, but it seems to pull up the hyd temp that does trigger the fault light at about there.
Have pulled the trans and motor oil cooler, there was some blockage (silicone) and cleaned.
Trans lube pressure was 10 psi low and replaced trans pump with cat rebuilt.
Changed hyd and trans filters and checked screens.
The trans is the first thing to heat up (hour to mid way and just keeps going up) and pulls the motor and hyd up it seems. Even at a fast idle not moving the trans will never cool to the same temp as the motor. The hyd is slow to heat up, but after 3 hrs or so of steady running climps up to the trans temp.
I don't think the tractor has a hyd cooler, it does have a third valve.
Pushing is 1st gear building pond dam, easy backup in 2nd.
It has been +100 degree weather.
There was a cat reman of trans not quite 2000 hrs ago before i bought the tractor.
Know that was done, was told torque was done but haven't got proof.
Have checked temps with thermal gun.
