I have a chevy 350 with a 350 tranny. I have a tranny cooler that sits in front of the radiator. In hot weather when I sit at a stop light or in stopped traffic my temperature goes up very close to 212 degrees. I just put a four core heavy duty radiator in. If I got a frame type tranny cooler and removed the one thats sits in front of my radiator, would my engine run cooler? And would it cool my tranny enough? I have a 2400 stall converter. Thanks

Permal Cool and B&M both make coolers that come with 10" fans mounted on them. I bet you could put one of them on a chasis and it would cool O.K.

What's wrong with 212? My 01 Tahoe runs just under 210 all the time, has since new. I doubt changing your trns cooler will change much.

I would say you need a fan that moves more air. Your CFM may be too small. Do you have two fans? If you are running air conditioning, you may want to have one fan running constantly while the a/c is on.

I really doubt that the transmission cooler is causing the engine to run hot at idle.

Ditto to everything they said ^^^^^.

You have an airflow problem

and/or you might be sucking hot air back into the front side of the radiator when stopped.

You need to seal the core support to the bumper, to the hood, and all around the radiator, seal your shroud to the radiator too. BIG fan with thermostatic fan clutch is best.
