Hey Buckeye Bowtie thanks a bunch for turning me on to the TCI web site! I"ve been searching for an answer conserning oil cooler applications specificly when the exsisting rad has no trans cooling ability and the answer was right there!!! I plan on towing a 20 ft boat behind my 51 chevy pickup on occasion. I"m still going to install a trans fluid temp sensor so I can see what going on down there.
