Hey guys well I was in a climb for about 10-15min at about 60mph and I look at my TFT on the edge and it was at 212. Is this normal i was not towing. my temp is usually at 160-175 on a flat road.

 

Yeah when I'm offroading it'll rise to 200ish at times since there isn't much cool air flowing through my tranny cooler. It's a lot of work for the tranny to push our truck at an incline at high speeds so I'd say it's normal.

 

I've seen 198 when going up long hills but I have 37s

 

At what point do I have to start worrying about the temp?

 

It depends how long you want your transmission to possibly last and if you do proper maintenance of fluid changes with it to determine at what temp you should worry.
