i got one of those stock tranny cooler that came off a thirdgen trans am (small one that mounts to rad).
right now i am just useing the stock rad with the built in tranny cooler.i have a TH350 with a shift kit and i was wondering if u guys could tell me if the one that mount to the rad would be better for me to use and will help?? should i install this?? is it better

 

You didn't state if car was stock or Modified. A few years ago When I had a Auto in my Car I ran the trany cooler Line Into The Tranny cooler that is built into the rad and out to the tranny cooler that mounted to the Rad, out of it back into the tranny. I think it would keep the fulid cooler and their by reduce thermal breakdown. Lol I sound Like a comercial well thats just my .02
