Normal transmission temps

[coobie]

I was towing my tractor 30Hp sub-comapct with loader and brush hog,on my tandem axle trailer in stop and go traffic,transmission temps were around 215 degrees. Are these normal temps?The outside temp was 81 degrees. I was towing on flat ground,no hills. When I got back out in normal highway speeds, 55 mph the temp dropped back around 180-190 degrees. Thanks for any info. coobie

I have the X-Monitor also the highest temp I ever recorded was last summer Aug 2004 in 97*F outside temp was 161*F showing on the X display. I was pulling my 28ft TT. I have always questioned mine reading to low, according to it being tied into the factory trans sensor.



Unloaded this time of the year, (summer) it normally shows 146*F to 148*F



According to my reading of the 2003 owners manual after 15 miles of normal driving the fluid should be 180*F considered hot normal checking it in "N" too hot to comfortably hold between the finger tips. Warm fluid considered 125*F.



Is your sensor located in the hot line, I'm still a little confused on where the correct location should be, some say hot line,some say pan, I don't know myself. At least if I see mine rising in temp some I usually just been adding 20 or 30 degrees to the reading I'm seeing on the X to get actual true temp.

Stop and go will always heat up the transmission, especially when towing. I don't think 215 is that bad. The problem with stop and go is the TC doesn't lock up and you are making a lot of heat with the slippage. Your X Monitor seems to be reading about right, mine normally reads 175-180 driving down the road, no stop and go. I have not towed heavy in traffic yet so I can't help you there. With a slide in camper and some stop and go I get into the 190's.
