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?

3rd gear 15% for 1/2 mile secondary grade is screaming 3rd gear all the way up. The speed limit is 45, I normally climb it at 50 mph unloaded, with no trans heat concern. During towing the speed is maintained 40 mph (normal), and the engine was not lugging or in 2nd.
