Trans Temt at 250???

[Jakeaz]

Hey everyone my trans temp got to 250 today and it ushally sits around 200 just wondering if im harming anything i live in AZ and its about 100 to 110 all day so im not sure if this is good or bad

Yea that's bad. Max should be 180. at 200 I'd pull over and let it cool before going. But since it does depend on ambient temp, it's about 70 above outside air I'd say.

hmm could an atf flush and get some fresh oil in there help to lower temps

It is worth a try and get a bigger oil cooler. I ran the largest cooler at advance auto parts and my OBs always ran cool.

Is your temp reading in the sump or after the TC?...BTW does anyone know what considered too high if a sensor is off the TC. I've got mine located there and have seen brief temps around 250 and steady readings of 220 if carrying the Bigfoot camper (4200lbs) and navigating sloping terrain.

I actually flushed mine the other day and it has been running a tad cooler. Better, cleaner fluid transfers heat better.

Seems a bit high, I live on the west coast so a hot day here is 80, but I never see more than 150 on my trans even when towing a 6k camper.
