Tranny overheat issue

[Pondsy]

Good morning folks...I have a 2001 with automatic tranny. It has (so I'm told) a DTT rebuild but the torque converter is just rebuilt stock converter.Truck runs perfectly fine until I put the plow on the front of the truck. First time it blew the tranny cooler line (again so I was told). We just got some plow-able snow. I did my driveway in am...no problem...drove 30 miles and parked it...4 hours later, drove 15 miles and started to do another driveway. Temps were not an issue when I started. On second swipe of driveway, trans temp shot up to 175...light came on dash...and O/D OFF light came on. I let it cool by running it in neutral. Tried to drive home and had to keep letting it cool. Can smell burnt tranny fluid but levels are fine.Called guy I bought it from to find out this happened to him as well, but he thought the shop fixed it.Any ideas...plows no good if I can't use it. Very frustrated...I have spent so much on the truck recently that I just don't have funds for much right now.Thanks for reading folks! Hope all are staying warm!

I think you got a typo...

On second swipe of driveway, trans temp shot up to 175...light came on dash...and O/D OFF light came on. I let it cool by running it in neutral. Tried to drive home and had to keep letting it cool. Can smell burnt tranny fluid but levels are fine.

275*F would for sure set the Trans Temp light. The factory service manual states the trans temp light will come on after 265*F...

So since the fluid has been scorched I would get that changed out a few times...
