auxilary transmission cooler

I have a 1991 wagyy with factory towing package.

Just got a new aluminum radiator that is supposed to cool transmission as well. I'm not sure if I can get rid of the auxilary transmission cooller that's stuck in the front of the car or do I need to keep it.

I don't plan of using the car to tow anything heavy or for any distance.

any input from people who swapped radiators is welcomed!

You can keep it or toss it. I would keep it. Your old radiator probaby has the tranny cooler in it as well.
Keeping it will keep your tranny temps down a little, and who knows when you'll have to tow something. Especially if you have a tow hitch

Thanks for the input.

I was hoping to hear from people that upgraded to an aluminum radiator and ditched the old tranny.

The pipes to the auxiliary seemed almost clogged on mine .........

You need a transmission cooler of some kind.

You can use the one in the bottom of the radiator, or the auxiliary. A typical installation plumbs the auxiliary in series after the factory cooler in the radiator.

Really no reason to ditch it unless your worried about leaks. I would keep it and replumb it, a cooler tranny is a happy tranny.
