I’m upgrading the transmission cooling system because it seems to be what is causing the overheating issue. When I took it to the diesel shop the radiator shop and the transmission shop they all said the transmission, radiator and engine are great.
I’ve done a compression test, timing, fan clutch, thermostat, shift modulator, new trans fluid, and it’s just slightly better but still overheating really fast under load.
I explained to all of the professionals that a short steep hill will quickly cause heat problems BUT it can go ALL DAY 3k on flat hwy. Also handles stop and go traffic fine and also around town no problem if it’s flat.
“Sounds like it’s the transmission” they all tell me.
The transmission has no shifting issues and has low miles because the previous owner had a rebuild done. I’m wondering if maybe a subpar torque converter was installed it could cause the transmission to overheat like this under load? Or maybe something else?
