I recently changed the radiator on my '91 SE and there are lines from the tranny to the radiator. Is this supposed to provide some sort of cooling? I've read prior threads suggesting a tranny cooler, what do you use to plug these outlets on the radiator if you do add a tranny cooler?

 

Typically you use this AND a tranny cooler. You simply run the tranny cooler off the return line from the radiator. If you want to TOTALLY eliminate the radiator (don't see why you would unless you had a previous tranny let go) then you don't need to do anything to plug them up, they don't have fluid running though them unless you have them hooked up. (Coolant and tranny fluid DON'T mix in there :-) )

Those who are using an auxillary cooler are also using their OEM radiator cooler. As Brain mentioned you just install the after-market cooler in the return line going back to tranny. When you open your hood and look down at the two lines, the return line is the one on "your" right. You can check the stickies at the beginning for any other possible questions you might have.

 

Thanks for the info guys.
