Transmission cooler

I guess your request is related to towing? 
​​​​​​Unfortunately I can't help, but I can see the result of 8 hours of towing on my Jimny rear axle. The axle is ​​​​​​waxoyled and it "boils off" the differential centre covers due to heat. Never seen this on other vehicles, so my little Jimny is obviously working hard.
Next time I tow I am going to take the external temperature of the drivetrain to see just how hard it's working.
Suzuki hint at this with a must do18K service for gearbox oil etc, as towing is classed as severe use (if admitted).
 So far nothings broken, but it does highlight the importance of oil changes.

Interested myself in what people have done.

 

I purchased this one from Derale:

 

Anyone buying this type might have a challenge finding a location. In honesty I didn't pursue it very long since it fit inside my front bumper.....almost like it was made for it.

 

I live in a hot climate 24/7 year round so I fitted a fairly large one. Made a bracket out of an old metal chair frame and reused the threaded holes on the jimny front bar

I'm thinking of fitting one too. I haven't yet decided where I'm going to fit it.

There is some space for a small cooler to the left of the radiator.  I was thinking of getting one, and fitting it as a pre-cooler so the oil runs though it first, then through the water cooled one, then it would avoid over-cooling, I hope

I was pretty much planning on doing the same thing. On my jimny the flow into the rad is on the right (when seated in the car).
