Trans Temp?

What temp is everyone's trans running? Mine seems to sit around 170-172, climbing a semi steep grade for only a couple minutes at less than 10 mph. and it climbed to 185.

I looked at a chart in a friends trans shop where it showed intervals for changing fluids based on temp. but not sure due to the fact it was a poster put out by a fluid manufacture.

Had Trans issues with my 01 so I am just trying to avoid them on the 13 I have. v6

After driving 70ish miles mostly highway trans temp was at 192. This is a 14 v6 though.

MY 2014 Summit V8 trans temp reads higher than the 2012 Overland V8. I read somewhere that Chrysler designed it so the 8 speed is more efficient with the hotter trans temp. I just think the 8 speed operates at higher temps than the previous 5/6 speed trans.

That is correct. My '12 runs at 150-180. Larger cooler and more fluid. New trannies are made to run hotter.

Same here. I have seen it peak in the low 180s after a long incline with the trailer, but even then the temp recovers pretty quickly after leveling out.

ZF, a german manufacturer makes the 8 speeds, not Chrysler...although these days everything seems to be owned by FIAT... But you are right, the 8 speeds on the '14 run hotter. Mine ran 199 exactly when completely warmed up without skid plates. It ran at 205 with the skids--I thought that was odd, but I suppose logical as the transfer case and tranny heat is reflected back by the heavy steel plates.

I heard somewhere that 1hr or more at 250+ is bad...but then again I also heard, "don't worry about it, I'm on birth control once..."

Chrysler makes the 8 speed for the v6, and soon they will be making the v8 version also.
