Trans coolers.

Question for the board.

A fellow local hotrodder yesterday was telling me that he managed to retain much cooler temps in his trans by running an aux. trans cooler, and NOT also runing it thru the radiator. Currently I am running my in conjunction with the radiator.

He was amking a case to me about pasing that trans fluid thru a 180 degre radiator actually contributing to the heat, not helping it.

So my question for anyone with a trans temp gauge is: Have you done a comparison running the radiator trans lines AND a trans cooler, vs. just a aux trans cooler? And what were your results?

Nobody done this comparison???????

I think you'll find this dicussed in the archives. Different plumbing routes will yield different results. From memory.....The coolest is probably just using the tranny cooler, especially if it is cooled by an auxillary electric fan. Second coolest may be radiator first, then tranny cooler.

But.... if you run your car all year round, you want to run through the radiator cooler to insure the tranny fluid is not getting too cold.

I did do some more researching on this topic, and it sounds like under normal driving conditions that just running a trans cooler keeps the temps cooler. But if you are going WOT a lot, and raelly hammering on it, that you are better off using the radiator in conjunction with the cooler.

For what it's worth, Len from PTLV installed my trans cooler in conjunction with the radiator.
