trans temp?
Hello I have a 05 f250 CC 4x4,when pulling a 29ft TT I was watching my trans temp go up over 200 deg . I was sitting in traffic during rush hour. I am planing a trip to Montana from Phoenix here in a couple of days. My question does the temp cool off when moving down the road? or could there be a problem with my trans cooler? Or am I worring over nothing. any Info would help...
Thanks DJ

200 is not too high. I took my 30' 5th wheel around the US this summer. My tranny temp went up over 200 maybe twice. When back down on way down the other side of that mountain. You have synthetic fluid in there. It can take higher temps....After the trip - 10,500 miles - I took it to the dealer and had the tranny flushed. You are good to probably 220-240 momentarily, so long as it starts back down right after that.

Trans temps can get to their highest sitting in traffic. It will cool off once you're moving. There's nothing to worry about, but checking for debris in the fins is always a good thing to do.

Hey War Thunder,
When I had my pillar gauges installed, I was asking a series of questions about the temps. My diesel tech from the local Ford dealership was saying the you can operate in the 220-240 degree range without have to worry about damaging the tranny. But you will have to change the fluids more often. I remember that at 250 degrees your seals start to burn up and your clutches will start slipping.
I will be getting a Mag-Hytec tranny pan pretty soon, I was looking at the differences. Mag-Hytec will hold 8.3 more quarts of fluid over stock. That's more than 2 gallons extra!
I called Matt @ Spartan Diesel and he quoted a good price for one. It's cheap insurance, better than have to buy a new tranny

Trans Cooler is air cooled by movement, there is no fan attached to it therefore in stop/go traffic it will heat up rather quickly depending on ambient temp.. As for critical anything above 220 is dangerous.. At that point the trans fluid breaks down.. If your constantly climbing above 220 upwards to 240 then you are risking transmission failure.. Adding a deeper pan with 4 qts over stock or higher will help keep temperatures down.. If you feel that your constantly hitting high then look towards a larger Trans Cooler or even an attachment fan..

No, no no, you were up late last night weren't you?
From the front of the truck towards the motor:
A/C condensor, Transmission OTA cooler, Power Steering cooler, Intercooler, Radiator. The Visconic PCM fan pulls air through all of these when the vehicle is stationary or in stop & go traffic. Also the Tranmission OTA cooler on the 6.0 is the largest in the industry.
war thunder, i would not be overly concerned about 200F in stop & go traffic in Phoenix, however since you have an A/M trans temp gauge, monitor it to determine its normal operating range for your truck. If the trans temp and water temp are running higher than normal, then check to make sure your Visconic Fan is working correctly.

thanks everybody for all the info .
Storm: I was thinking of a trans cooler with a Fan. like B&M or something like that.
Black hat: I was pulling a TT from Mesa to north Glendale up the 51. During rush hour
that was my main worry and the temp was up around 195 or so I was checking the fluid yesterday and it was a little low. Today I got a trans service done here on base (Fort bliss). So I think from all the info I should not be worried to much. unless it stays high?

If you want to do a remote mount with fan strictly for the Trans Cooler it will help.. A cheaper solution is getting a larger trans pan that adds at least 4qt more will help keep it cool..

DAMN!, You're right Storm.................
I can't understand what the diesel tech was talking about than, maybe he was talking about something else...
Sorry, War Thunder, I just quoting what was told to me. I'll just sit in the corner and say nothing.....................

I wish I knew what he was speaking of myself.. Most everyone here will tell you that 240* constantly is dangerous.. Regardless of changing the fluid early..

Try to keep the TC locked up as much as you can . Stop and go traffic will kill the temp faster than anything. Heat is the number one killer of automatic transmissions.

I was wondering about that 220-240 statement as well.
I had it once this summer in SD when my tranny temp started climbing and hit 220. It was weird, I was pushing pretty hard (towing and running about 78-80) and it was 110 outside, fan was running, engine temp was floating between 215-220 and then the tranny temp just started climbing. Slowed down about 5 MPH, temp went right down and never had a problem again. Seemed like a thermostat sticking or something.
