Overheat Question

Hello Everyone...last saturday I pulled a 28ft bumper pull about 40 miles for a guy to his camp area. When I arrived at the site and unhitched, their was transmission fluid on the ground where I had parked on the passenger side just to the inside of where the tire was. The passenger side wheel well had fluid up in it.

I looked under the truck and I couldnt see where it was coming out at, but it was dripping a little bit from fluid on one of the cross member supports so I checked the fluid on the dipstick and it was just as it should be and just as it has always been since I have had the unit.

While pulling my trans temp gauge never got above 190...170 and 180 while moving and saw 190 after I parked before shutting it off.

Never once did the truck drive different than normal, shift perfectly normal every time, and on the way home the trans temp stayed about 160 the entire way home....85 degrees out hot sun, that is normal for my truck since I have had the gauges.

Took it to the shop they checked it out and said that the fluid came from the overflow on the front becasue the transmission had gotten hot. The computer they put on the truck had registered a 215 degree reading from the transmission temperature. They had driven the truck and eveything...nothing else noted to be wrong and still shifts normal.

Do you think my transmission is "trashed" and just hasn't died yet? Reason I kinda need to know is my uncle just passed away in Arizona and I need to know if I can make the trip to AZ from Ohio and trust the truck.

Thanks guys!!

Did you happen to back the trailer up a hill at the very end? That is about the only time I have heard of the tranny doing that. Even 215 isn't out of the normal range so that is not overheating it at all.

I agree with jay. 215* isn't terrible especially for a short time. If you back up a heavy load with these tranny's the stock shaft seal will get hot and deform and puke some fluid. If you only do it once or twice, it shouldn't be a problem. If you continue to do it, it will happen more and more frequently and easier and easier. The seal is silicone and will deform. They make a viton replacement.

The only backing at all was about 3 feet to go onto some leveling boards after we arrived at the site to finish up the parking job we backed onto some boards

I have no good explanation. Backing onto a few boards would not cause that. I do that all the time.

When the shop took it for a ride (no load) It registered a 215 reading?

What will read a 215 in history from past events?

I think i would take out your trans gauge and drop it in a pan of hot water 200 to boiling to see if you gauge is ok to make sure what you are looking at is accurate.

The overflow is up by the inside of passenger wheel?

#1)No...the 215 came from a computer laptop that was put on the truck
#2)Not sure...some type of laptop connected up to it

#4)The inside passenger wheel had fluid "blown" up inside of that area...have no idea what area that an overflow is located in.

I find it hard to believe they ran it unloaded and read a temp of 215. Does the truck even track that kind of data?

Not sure...just what I was told. Along the same "thing" that stores that I was lead to beleive that it watches and remembers things like over-revs and such and stores that for retreival....unknown just relaying what I was told.

Maybe a clogged line, that would make it overflow and be warmer than normal.
