You don't have to run the coolant lines through the radiator, but you do have to try to keep it cool. I'm a tad neurotic about cooling my tranny. I run a Derale cooling pan (the kind that has the tubes) as well as an external cooler.

My 46 Chevy Truck's 700R4 trany dies. The guy that installed the trany, put a small trany cooler under the truck. This was done way before I bought the truck. The small cooler didn't get much air movement. The new mechanic is installing a high efficiency cooler in the front of the truck to get better air flow for keeping the trany cool. I don't race the truck, but want to drive it on long drives. The truck has an old radiator that works well with the 350 LT1 engine. It runs 185 which is fine but it has no transmission lines for cooling in the radiator. Do you have to cool the trany through the radiator, or is it better to have a large separate trany cooler instead? What about a fan pushed cooler, would it be better. After the cost I am investing, I don't want to go through this again! HELP! Dan Mascheck Wharton, TX
