my tranny temps rarely see over 130 they are usually around 110 up here

the other day while climbing a hill in 4 wheel drive the temps got up around 180 it was about a mile and a half up hill or so!
loaded with about 1000 lbs of coal

Is this common?
this never happend when towing in fla with a 25 ft boat

yep, sounds fine to me, those temps dont indicate a problem at all

 

[fishinfool98]

but why the rise in temp?
the hills

The stock trans will do that if you are loaded and/or climbing hills at speeds low enough where the torque converter doesn't lock. A lot of heat is generated quickly. Try pulling about 9000 lbs up very steep and winding Colorado mountain passes at speeds of 30 mph or less, and you'll peg the gauge in no time.
