Transmission cooler for kluger

Can't comment for the Kluger, but I have Prado towing a camper of around 1800Kg. I fitted an additional trans cooler to it after reading of the trans fluid temperatures others were seeing while towing. When I fitted the cooler I also changed the trans fluid, it was burnt brown.

I would suggest fitting a cooler would be a good idea to keep the fluid temperature down.

All auto transmissions will benefit from extra cooling when towing, some almost need extra cooling when not towing, and for every 10 degrees that you can reduce the trans temp you can double its life. Having said that it is still advisable to run the trans at around the 60 deg mark so as to 'boil off' any condensation that may enter the transmission.

I would also recommend fitting a Scangauge 2 with the appropriate coding installed so as to monitor the transmission temps, especially when towing, and drive in a manner and by selecting the appropriate gear to keep the temps under control.

My Hilux tows a hybrid camper with a GVM of 2400, and I have fitted a trans cooler and scan gauge (ARB). Sound investment in protecting your vehicle, in my view.

hi
It may sound obvious ,pick the largest u can fit in the space 12 x 12 inch .
Thickness ranges from 3/4 inch to 2 inch
'
Cooler type construction is very important
Only use plate or plate and fin type
The serpentine tube coolers are not that effective . U need a large unit to do only average cooling .

Thanks for all your comments yes I will definitely be installing a cooler although my mechanic has told me there are no kits available for the kluger he will have to make one up cheers.

I have never spoken to a transmission specialist that has said not to install a cooler, even when not towing. According to the penrite tech heat it the major enemy of transmission fluid followed by particle contamination, past 130 degrees it is breaking down fast, at 200 it self destructs in minutes, the cooler in the radiator at best gets it down to 80 degrees, but remember it isn't all of the oil that is going through the cooler, it is pressure regulated, most of the oil is going straight back through the workings and only a percentage through the cooler.

Next comes the great debate, do you put the cooler before, after or in parallel with the original?

I opt for before because the hotter the fluid the better the transfer through the cooler, but then if it gets it below 80 degrees the radiator will add heat, but if the tranny is working hard it will never get the fluid below 80 degrees, but this is only my opinion and there are many valid reasons for other configurations.

Just a quick update I just found out the kluger does have its own cooler and it’s not built into the radiator it’s on the passenger side just under the fog light it’s not a bad size I’m wondering if I would need to improve it?
