That's what I was afraid of that art to be real cheap

Are you sure it is the trans temp light?

With tillage and that trans it shouldn't get hot or at least over heating. Your engine would over heat long before the trans. If you already changed the fliters and sensor and it does seem to be heat related. I would just double check to make sure it is the correct light.

Does your dash look like this one?

That's it the #1 and #8 lights come on and start flashing. You can unplug the sensor and light goes out.I notice there were some valves by the filter I am going to check for trash.

Do you have a non-contact thermometer?

That might help to get a better idea of what is going on. Use it to try and find any hot spots in the system. It could be a stuck valve that is trying to send fluid all the time.

It is possible you have another bad sensor, but not likely.

No were can you get one

Most auto places (advance auto, autozone, etc) now carry them, Sears, Grainger, MSC, McMaster Carr.

They start at about $25.00 and can be a couple hundred. Very good tool though for tracing a heating issue.


These in the link are some sears has.

If your light is going off that low something is wrong with the sensor or the wires. If you disconnecting the sensor does the trick then I would say the sensor. You might want to discuss further with the dealer. Maybe they can test or explain to you how to test it.

The outside is going to be cooler than the inside of the trans, but that is way to low for the sensor to be going off.

It is also poor design on Deere that you can un-hook the sensor and the light goes out. You would think they would have it set up so the light would come on without the sensor. Now you could have an "open" either due to a bad sensor or a break in the wires and you would never know it.

Were you able to find the problem and fix it?

i talked to a nother dealer and he said that it was ether a clutch fan was out or a line was blocked to transmission cooler

That would only make sense if your oil was actually overheating.
