Might have been clearer if you'd have asked about an AUXILIARY transmission cooler since EVERY automatic transmission already has a cooler as part of the radiator. The auxiliary cooler is mounted, usually near the bottom of the radiator.

that service tech is an idiot. If you are going to tow any thing whether it be a small boat trailer or a full blown camping trailer, you need as cooler period. if you don't get one then start looking for a new tranny, you will need one sooner than you think. I knew a guy who told me he wouldn't drive a new car or truck across the street with out one on it. That was back in the 50's, when automatics just came out. this guy knew the importance for the cooler on a tranny, and was IMHO ahead of his time.

Yes any transmission shop can help you out, but I also agree to specify that you want a stacked plate and not a tube and fin type of cooler. Also specify that regardless of the cooler type you will not accept the push pins through the radiator type of mount. That's the plastic straps below the picture of the tube type of cooler that Happytrails2u2 posted. I have seen these straps over time damage a radiator as they are essentially hanging the transmission cooler off the cooling fins of the radiator. A decent trans shop or mechanic should be able to adapt either type of cooler to eliminate the push pin style of mount.

For a TV that is near maxed out It wouldn’t hurt to add a engine oil cooler at the same time…

"Most" vehicles that have a trailer hitch installed as part of a "tow package" will have some sort of AUX trans cooler installed by the factory as well.

Every automatic trans in the world has the integrated cooler in the radiator, or at least 'should'..

Some models will have the aux trans cooler sandwiched between the rad and the A/C condenser, or even installed right next to the fan under the hood..

Most will have them just behind the front grill. You may actually see several of these small radiator looking things however... A lot of vehicles have power steering fluid coolers up front as well..

Anyway, take a peek behind the grill and you may be surprised that you already have an aux trans cooler!

My guess is that you already have one and should be good to go.

Good luck and enjoy!

I'm betting it has one as well. So before you go buying one. Trace the trany lines out of the Radiator, and make sure they don't run thru a cooler before they go back to the trany.

Although there are many other aftermarket types available, for my 2004 Avalanche I bought the factory original cooler from GMPartsDirect.com

The part number is 12497071 - COOLER KIT.

I agree on the push pins though the radiator I didn't use them on mine either. As for the stacked plates vs the tube type I looked at both while making my decision on which one to buy and decided on the tube type. Probably because I'm an old geezer and the tube type looks like something I remember from the old days and evidently somebody thinks they're still a good idea or they wouldn't still be manufacturing them.

Remember points and dwell and carburetors and manual chokes and the like?

I do too, but I'm sure glad we don't have to deal with those things anymore!

What the stacked plate design does is the same thing a radiator does. It thins out the fluid as it goes across the 'plates' and much more heat is able to be extracted from it. That's why you can get away with a lot smaller physical size stacked plate compared to the tube and fin..

The tube part still has a pretty large volume of fluid in it and yes, it does pass back and forth many times and is an effective cooler and probably better than no aux cooler at all, but I'd still vote for stacked plate every time..

Good point I do remember changing points, plugs and condenser every 15 or 20 thousand miles and plugs a lot more than that if you had one of the old muscle cars. One weekend of idling around the cruise joints with an 800 double pumper and a big cam and you were ready for new spark plugs by Sunday evening. If you could carve a pine knot to fit the spark plug hole these days the electronic ignition would fire it!

Yes, I remember them well from the VW Bus and Bug days.
