Default How big do I need

I have a bad radiator on my 86. I have another radiator from an 86 Bronco. Its a straight drive. My truck is an automatic. So now I need a cooler for the tranny. How big of one do I need ? Or is there a seperate one already. I havent looked at it yet. I was going to fix it tomorrow.

Default Re: How big do I need

It's better to get a radiator with the cooler for an automatic. It not only cools the tranny but makes sure it doesn't get too cool. Depending on the electronic set up of the vehicle, tranny fluid that is too cool, it will fool the computer into thinking the engine is cold too and make the engine run rich. Which will lead to other problems in the long run besides increased fuel consumption.
