KATROL's Hot box

[katwoman]

Towed a trailer the other week, with no more than a tonne of stuff. Gearbox got that hot that it felt like heater was on full bore in cabin. She's been to the doctor's and they cant find anything wrong.
Should I get a second opinion? Or do the GU's get warm when towing?
Katrol needs to be a tow bus, so has to be right.

If it is an auto, then they get bloody hot. Mine is the same in the GQ - feels like you actually have the heater on. That said, obviously don't know how hot yours is running, so get a second opinion for peace of mind I guess - I did just to be sure.

hi
ive been hauling wood with my 4.5 auto a ton at a time and a camper and never saw my temp needle go past half way even on the hottest days
have you dipped your oil when you think its hot might be lower than it should be under load
i run mine a tad higher than recomended for steep country
have you put in the right oil
have checked the oilcooler fins might be blocked ,bugs damage

has it got a seperate trans fluid cooler ? if not, installing one woud make a big difference.

Thanks guys. Yeah, it's got transmision cooler. Its got about 5 in there ! ( for different jobs obviously). Engine temp doesnt normally get past 100c, thats only with the aircon on. May just get a auto tech to have a look.
But food for thought..

might be worth installing a transmission temp gauge so you can see how hot it is actually getting... just for peace of mind

Yes, is something I will look into, nothing worse than cooking the gearbox.
