i know this has been asked before but... ordered a new rad. from postons. all new rads. for our cars have to have an adapter to connect the trans cooler lines (which i assure you is a bummer) (you have to loosen the air cond. cond. ), and i finally did run the cooler lines thru the trans and then thru the very big rv cooler mounted in frnt. of the rad. ques. being.............could i have gotten by with running the trans. cooler lines thru the rv cooler only? would that be better? made it to one car show this way with no detectable problems. do not have a trans. temp. gauge.
