2005 6.0 auto trans suddenly running way too hot

Does anyone have an idea why suddenly overnight (after picking my truck up from the shop for motor work ) the auto trans is spiking the trans temp gauge
and the scanner is saying 245 deg F under no load normal diving !

Welcome to the site. I would do what is called a cold soak. Let the truck sit over nite. Then on a cold start check your temps . They should all match.

I turned the key to on position and the dash gauges barely move which seems normal.
The scan gauge reads 81 deg F for all fluids.........
now what ?

I am thinking it's the in pan senderor related wiring ? not that a trans issue is out but

your coolers don't even come into play until over 180ish

the previous recommendations were good but now
if it were Me I would heat gun the pan and see if it is actually that high


how fast does it peg the gauge ?

It takes about 20-30 min to get to what the sensor is saying is 250 deg f.
I suppose I could drive it, get it "hot" , get under and drain some fluid or put a pyrometer to the pan and see what it reads.
Thanks for the reply

I was snoopin around under there one time and thought I saw a very easy place to install a manual temp guage type set up that you could buy at any auto store. Check that out. Could be a easy way to get the fact cconfirmed or denied.

suddenly overheating tranny

I'm hooking up a digital thermocouple temp reader I use at work that's super accurate right now as we speak.
Thanks again

I drove the damn thing and the temp slowly started to climb to 235 deg F.
Hooked up a digital thermometer to the coolant ( stuck it in the degass bottle) and compared it to what the scan gauge was reading to get a sense of accuracy and calibration so to speak. Then crawled under the beast in the 110 deg heat of so cal and the temp said 225 deg f almost matching the scan gauges readings. I said screw it and figured a fluid change wouldn't hurt anyways so dropped the pan and it looked clean.
Replaced the TFT sensor for $15, filters, etc....put it all back together and it still does the same thing ! Still overheating ! Never, ever ran over 185 even towing hard up hill in death valley.........weird it only stated doing this right after getting it back from the truck shop. Just my luck.

I would suggest that since your trans temp was fine before the work was done on your motor that your problem may be associated with that work. I would go through and check all the wires, connectors and so on to make sure your motor was done properly.
