It did for me, but I had my cooler directly in front of the radiator, between the AC condensor and radiator. Not sure where yours is.

I see.

Mine is in front of the condenser. Fan --> radiator -->condenser--> cooler-->fat-lip bumper

I'll need to check if air from the fan still gets to the cooler but I doubt it.

Thanks again.

Any decent size cooler, is usually better than the stock one in the raditor. If you consider that it has 180-200 degree water running past it, it can only help so much. However the reverse side is that water does transfer the heat faster than air. If you place a cooler where there is good air flow it shouldn't be a problem. Remember when your sitting still in traffic your trannys not building up that much heat. If you do a lot of crawlin or your loaded down, a cooler with a fan like mt goat has would be good. Nice job mt goat.

Yeah check the air flow there, slip a dollar bill in front of it with the fan running and see. The good thing about being in front of the AC condensor is the heat from the AC won't be hitting the ATF cooler.

My guess is with 2 coolers it would be good there. A trans temp gauge will tell you for sure. You don't even have to have the gauge visible all the time, you can stuff it into the glove box and just monitor it occasionally, after a while you'll notice the trend.

I agree, most of the time my ATF is much cooler than my coolant. If I was running the ATF through the radiator I'd be heating the ATF not cooling it.

Yesterday driving around the city (75 degree day) my ATF temps were in the range of 130-170 F. Since my little ATF fan doesn't even kick on until 180F the fan never ran on the drive. At the same time my coolant stayed around 190 F with my Taurus rad fan bearly running.

There's still adequate airflow infront of the cooler. Tested with two bills and both stuck to the cooler, so air pull from the engine fan still reaches the cooler . Time to start saving for another TRD ATF cooler

Thanks guys!!

Don't forget to check the little cooler on the inside of the pass side frame rail. I thinks it's for the tranfer case. When I bought my 4Runner mine was so clogged with dirt and crab you couldn't see thru it, which means air coudn't get thru it either. Since the two are connected, the ones heat effects the other.

I think that's just on the pre 95.5 auto trannies.
