Looking under the hood of my montero there are alot of coolers. a Transmission cooler, i think an oil cooler, and a fan that hooks up to what i think is my a/c.

Has anyone found it beneficial to add a fan to the transmission or oil cooler? How about another fan for the A/c? Looks like it would fit.

I did have the a/t light come on at the exact moment i summited a rather vertical hill. I think its time for a flush but a cooler fan is attractive as well.

using our search function nothing comes up when i search "Montero transmission cooler fan"

Im guessing it has not be attempted alot on this form, ill post my results for future searchers

One of the many common fan replacement methods has been to use either a Volvo or Ford Taurus fan, but only for the primary cooling.

When folks start down this road of 'potential' modification, we stop and ask them why? The 'why' is important and can save hours of time and also wastes of $$ during the evaluation.

so...why?

my AT light came on as i was off roading. It happened WHen I went up a very steep hill that took a solid 5 min or so.

That would be the Jeep AW3 transmission if that's a '97, correct?

Still the same old Aisin Warner tranny. Makes a lot of heat with the converter unlocked. You pull a steep grade with lots of slip, the converter really heats the fluid. You might gain some marginal improvement in at temp with rad airfow, but I'd let it go.

How good is the radiator? This may be a symptom of a radiator that needs maintenance (flushing needed, rodded, re-cored or even replaced).

That's what I thought. Yea, the OP would probably be better off looking through the Cherokee threads. Lots of info on there about transmission coolers.

What I got off those threads was to pull the transmission out of the radiator and install a standalone cooler. About half put one in front of the condenser/radiator. The guys running 37/38+ tires install a separate cooler with its own fan and put it where it'll fit.

Mitsu never did a deep sump pan for the AW3, but there is a company out there that does sell one. The dipstick is on the PS side though. For whatever its worth. General opinion seemed to be leaning towards that not being worth the effort - what was really needed was a separate cooler and/or fan.

I'm not a huge fan of the in-radiator cooler. It is nowhere near as efficient as a properly installed stand-alone unit.

That's what I was thinking, too.
