(per the above) You must have a transmission cooler in your radiator regardless of what someone has told you for the transmission to last. Auxiliary coolers are just that, in addition to. Water cools better (faster) than air always, period. The transmission fluid comes directly from the torque converter at a much higher temperature than the water in your radiator and is cooled to the water temperature fast. Then it goes to the auxiliary cooler to be cooled far below the water temperature. If you don't need a cooler in your radiator why does GM spend all that money doing so? If you wanted to cool a red hot piece of steel fast would you stick it in water or air, see the point. Your transmission will run cooler with a lock-up converter. This is more important with stall speeds of 2000 RPM or higher.
The most often asked question is should I bypass the radiator cooler when I install a auxillary cooler.
Most cooler manufactures and automobile manufactures information we have read, recommends installing the coolers In-Series with the factory radiator cooler for maxium cooling efficiency.
So unless the manufactures who have spent 1000's of hours testing different installations are wrong, the suggested cooler installation is in-series......
Transmission > Radiator cooler > Auxillary cooler > then Back to the transmission.
If you must bypass the radiator because the cooler tube is leaking or for other reasons, be sure to increase the size cooler you install by 1 to 2 sizes. |
Thanks for the feedback! That is what I was trying to figure out, and that is, why dont the manufactures just use a aux cooler? And maybe I just misunderstood him as to the fact that I need to run both for long gevity. I have used aux coolers before and had them hooked up as you mentioned, and never thought you could just run the aux cooler without the radiator cooler. I had to have misunderstood what he was saying, and I will run both. I have read that for every 20 degree drop in transmission oil temp doubles the life of the transmission.
