Torqshift temp problem
I have a 2003 F350 with the 6.0 and Torqshift auto and recently I had the tranny temp spike and have the check gauges light come on. The tow/haul light was also flashing.
At the time when this happened I was just driving across town without a load, I touched the pan and there was no way the temp was anywhere near what the gauge was reading???
I started the truck up the next morning, and the tranny temp gauge was already 1/4 of the way up just after starting and within 1 mile of driving the gauge pegged again and the tow/haul light began to flash with the check gauges light coming on too.
I checked for codes, didn't find any...
Any thoughts?
Thanks!

I would check the temp sender. Take wire off of sender and temp should go to cold. Ground sender wire and temp should peg to hot. This test will prove that your gauge is working properly. It might also be the gauge but is most likely the sender. Gauges rarely fail so i would start with the temp sender. Slap a new sender on there and hope for the best.

Do not have any real experiance with problems with the Torqshift auto but i do know they have a thermostat that controlls flow to the tranny cooler, is it possable that the thermostat failed closed causing no cooling loop and the tranny is actually overheating, again i do not have much knowladge just know what i have read. I guess you could use a infread heat gun and check pan and or cooler line temp. Just my .02 cents. Let us know what you find.

Same problem here, scanned it at Ford and I'm getting an intermittent high temp input from the sensor, It will take a few minutes for it to shift into OD on the highway sometimes and gives me a rough 1-2 and 2-3 shift sometimes. I've got a new sensor just haven't had the time to switch it out.

I'm kind of surprised to here that there's a thermostat for the transmission cooler. My ScanGuage monitors my engine and transmission temperatures. When it's cool out my transmission temperature runs cool (135-145) and it's warm out it will runs at a higher temperature. When I run with my fifth-wheel the transmission runs around 180 + or - 10 degrees. In contrast to the engine, which obviously has a thermostat, runs 190-195 all the time.

There is a thermostat in the TorqShift. It's in the pump body, and it's nominal temperature to open is 165F.
When it's closed there is still flow to the cooler, but it's reduced by 90%.

Where is the wire located? I belive the sending unit is on the valve body inside the tranny pan.
