tranny cooler brands

Postby fungus2k [OP] » May 29th 2009, 2:06am

just wondering what brands of tranny coolers people here have used, and your opinions on which one i should look into. I am thinking about putting one in, even though i don't do any towing, the additional cooling capacity will put my mind at ease.

The most popular brand is Tru-Cool Stacked Plate coolers from the old forum and current members.

The guys on the Blazer forums swear by the B&M supercoolers - for one, they have a viscosity bypass so they don't overcool in cold weather.

I really think the best tranny cooler you can get isn't even a tranny cooler. Just get an aluminum transmission pan. Several companies make them and they aren't too expensive. They have a higher fluid capacity holding 2 to 3 more quarts and have fins on the bottom of them to dissipate the heat. Plus no extra lines to run if you plan on using the stock cooler.

You also forgot it makes filter/fluid changes easier with its integrated drain plug! :mrgreen:

Thats very true. I know GM wanted it cheap, but I just didn't get why they didn't put drain plugs on ever component that held fluid.

Manufacturers didn't do that. It's incredibly stupid, I agree. I added a deep aluminum pan with drain plug to my '73 motorhome (Dodge 440 with 727) and it's been the best thing I've ever done. What a mess-saver (and major time-saver, too).

But when it's time to change the fluid and filter on both the Bravada and the Astro, I'll be adding a drain plug at the very least.

i saw the larger drain pan as well, but could only find them for 150ish, and the cooler was about 50 bucks, which one do you guys think works better?

I have seen ads claiming anywhere from 20 to 50 degrees in decreased heat. The only sure way to know is to have a trans temp gauge installed with the pan. Even the cheaper steel ones will work if they have the cooling tubes mounted on the bottom.

But I can tell you that at school we did an experiment in our automatic transmission class. We welded 4 fins onto the pan of a 700R4. Each fin was just bar stock that was 3/4" wide and the 10" long. We measured a drop of 25ish* while the trans was on a trans dyno when a cooling fan was blown across it. They do work.
