Trans oil is getting excessively hot according to the code
So, you're going to have to give a little more info, in order for anyone to start helping. Lets start with a make/ model/ serial #, maybe some symptoms.
HH has a John Deere 310SL. No serial number posted yet.
Let's start with the basics. Is it full of oil? Are you trying to push in third gear? When is the last time you washed out the radiator?
Clean radiator and oil cooler
It’s a John Deere 310 sk haven’t really looked yet at the machine been busy on other things just trying to get some info and I’m suspecting maybe a cooler issue not sure yet
And yes oil is good and the machine is operated by other people and when the question is asked are you pushing in third gear or fourth the response is no but nobody really knows the truth of how it’s getting operated if we take it and push in second or first it does absolutely perfect temp wise
Sounds like you already know what the problem is.
I'm curious if you have two 310's. You have another thread titled ---> 310sl throttle knob not responsive
Sorry it’s 310 sl
Serial number would be most helpful. Spitballing here, but maybe the part below is defective if all the basics have been eliminated. The valve below controls the coolant flow to the hydraulic and transmission oil coolers (they are liquid to liquid coolers).
