You just need to flush anything out of the trans. If nothing is in there, and money is tight, check out the local dump for old refrigerators to get the condenser coil from to make yourself a trans cooler. (just flush it out with carb cleaner and compressed air) Last one I did that with came from a Kelvinator! <G> From: Joe <jgray_55@xxxxxxxxx> Subject: trans fluid in the radiator?? To: AMClist <mail@xxxxxxxxxxxx>, Radiator blew out on my 67 Ambassador (290)convertible Monday night.Went to see my Aunt after my cousin passed away at age 58 from a fast moving lung cancer(only diagnosed a month ago)!!!!! Radiator Blew all over her driveway. Core was rotted bad...so i took the one from my other 67 Ambassasdor (343 car) to the rad shop. It pressure tested/flow tested fine,he also flushed it out. I installed it Thursday night after the visitation at the funeral home..BUT...after warming it all up and cooling it down...it "appears" to have a layer of red tranny fluid floating on top of the coolant in the top tank! I Assume the in tank tranny cooler blew out...BUT I DID NOT have the heart to see if the tranny fluid was milky!!I had added two bottles of CarQuest anti rust to the coolant(looks white). The tranny was rebuilt a few years ago...works really super(at-least it "DID").My luck keeps getting WORSE lately. Any suggestions "IF" i see milky tranny fluid? Being laid off...prohibits a rebuild of the trans. I HAVE to get my wifes 727 trans done for her AMX....new 401 has been ready for almost a year!! Also need to have the fellow do the trans for my 401 Gremlin. Gotta go to bed...pall bearer in the morning! Wish me luck...if possible,Joe
