2004 4l80e hot trans on hills
Hi my 2004 k2500 transmission gets up to 230f on any grade locked in 3rd gear and not gear hunting. Why is it getting that hot on hills?

On GM full sized +8.6K GVWR will have hydro-booster instead of vacuum booster
for power brakes
Uses the steering pump as HIGH PSI source and is plumbed to it's own
external cooler on the left side of all other external coolers
This picture is of my front end while at the shop fixing the front
right fender and busted right steering knuckle from smacking a LandRover
which jumped a stop sign (I was through traffic, so no stop sign for me)
Tough to see, but it is on the drivers side and is vertical tube fin
Mine also gets VERY hot off roading, but not like Burbman in the sand.
I move boulders out of the way with the wheels...nudge up to them with
the tire just to one side and turn the steering wheel
Burbman, check your front end joints...and stay away from MOOG. Junk
now that they sold out and the new owner has them made in China
I've go NAPA HD in there now and waiting to see how they perform...
Back on topic...I don't see how the power steering and hydro-booster
system is tied in with the engine coolant system. Even the ATF in tank
is isolated and would have to spring a leak (it is inside the cold
tank of the main radiator)
The power steering/hydro-booster system is completely isolated from
both the engine coolant system and ATF system
