Hi Dan, I recently installed a 700R4 in my 71 Blazer. To keep it cool I also installed the largest "plate" type trans cooler that B&M makes and skipped the cooler in the rad. According to Bow Tie Overdrives, you should install a temp gauge in the trans pan and monitor the temp, which should operate up to 150* F. If it runs hotter than that you need to improve your trans' cooling system. So far in this cold weather my trans temp barely makes it to 100* F. I'll have to wait and see how the summer temps are.

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
