 |  posted 05-22-2001 09:18 PM         Hey gang, I am ordering a new cooling system for the 71 and had a question about a trans cooler. I plan to go with one of the cheap "NASCAR" series radiators by Griffin but it is not provisioned for use with an auto trans. Alex said in a post awhile back that I could get away with running a big tranny cooler all by itself and the biggest one I can find so far is a B&M 24,000 lbs. GVW 11"x6"x1 1/2. I will be running a C-6 with a 3500 stall and this is primarily a street driven car so I am sure slippage with create plenty of heat. Question is, will this cooler do the job or will the fluid even reach proper operating temperatures?

 There are several companies that make coolers. Setrab, a european company that supplies OEM's like Porsche and Mercedes, makes a cooler up to 7 1/2 x 16. Fluiddyne, who makes a great deal of high dollar NASCAR parts, makes a cooler up to 14 3/4"' x 9 1/4" x 2 1/2, but it sure ain't cheap. While you are playing around, why not install a temp guage so that you can keep and eye on it. Jay ------------------Jay Kilroy

With the lines in the radiator I would think the fluid would be heated up a bit by heat from the water it is beside thus never getting below a certain temperature.

 |  posted 05-25-2001 11:53 AM         I run my street car with just a cooler. I took the lines out of the radiator and have never had a problem. My reasoning was, most trans shops want the trans temperature around 180* tops. If the engine radiator is at 200*, then it is heating the fluid up, and not cooling it off. I would not be worried about it not reaching operating temperature.
 I run a big cooler on the street with a small electric fan on it to help cool the fluid off. And remember, I run an 8" convertor on the street that stalls almost 5000 rpm.
