aw4 running temps?

I just installed a trans temp gauge in my 89.

I was surprised to see the temp get way up to 230*f as I was climbing up out of Borrego Springs.

Not towing or heavy load. Engine temp was 210*f, which is good.

So i am not sure if my cooler is clogging or what.

Trans ran good, you wouldn't know it's hot if you didn't have a gauge.

What are your guys' temps usually at?
 
AW4s do like to run hot. I hit 260F once when going up mountains on 35s. The big tires and mountains are definitely what causes my heat issue, what size tires are you on? Do you have the factory radiator integrated cooler or are you running an external cooler in front of the radiator?

I've pretty much learned to keep it out of "D" going up any sort of grade. I keep it in "3" now and will only ever shift to "D" if its flat or downhill. This helps a ton with keeping temps down. In "3" it never goes past 180F. When I used to keep it in "D" it would commonly go to 200-230F.
