Hey Don, welcome to the world of "A" Bones. Now you know why they are called HOTRODS! You should really look into a radiator with trans cooler installed. I run a Walker radiator with a built in cooler and also use a B&M trans cooler mounted at an angle agianst the 4 bar crossmember. The 700R4 needs to stay under 200 degrees. For every 20 degrees above 200, the life of the trans is cut in half. Trans life is around 200K miles. So temp is very important.
