Was thinking about putting a tranny cooler on the aurora. This engine runs crazy hot and so does the tranny. Anyone running a tranny cooler? If so what seems to be the best one or most popular for auroras?
Also what about an aluminum radiator for thee cars..thats gotta help with the engine heat right? Theres shops by my house that take radiators and make them custom right there in front of u, they have a welder that weld different end takes on them so hoses line up perfect etc...

B&M Racing is a good source for trans oil coolers.

There is a stock trans cooler, so technically all of us run one. How hot do you think is "crazy hot"? And have you checked the temp gauge against a scanner with live data? 220-230F is a normal operating range, up to 240 in an Aurora is reasonable for short periods (high speed fans kick in at ~238F)

Thanks bob, didnt know that. I had a 98 supercharged regal that saw only 210 from a scantool reading, then consistent170s after I installed a desert fox tranny cooler.

Don't all year Auroras have the trans cooler in the side of the radiator?

These cars all have aluminum radiators that have a built in transmission cooler. But it runs with the engine temp, so adding a separate one may be a good investment

Agreed. If your trans fluid is still at 100% you have never experienced any overheating issues though. Someone has added one one to a 2G though. Mounted in front of the condenser IIRC. Just cannot remember the member or locate the thread.

My 3 cents:
Good discussion. Transmissions don't like extream heat. For one heat breaks down fluids, and secondly components, seals and gaskets degrade quicker, this we all know. A properly researched trans cooler (size) for your geographical area of summer heat combined with stop and go traffic, or towing, (Etc), are prefect scenarios for an additional trans cooler. Here in South Carolina we definitely have the major temperature swings. I will be installing one when I do my new radiator and simply insulate it some in the winter, I may even install a fitting and temperature gauge and report back

I'm actually running on all aluminum radiator with three rows of cooling. It's an aftermarket unit that comes with the built-in trans cooler and inlets for oil cooler as well. This was specifically designed for the 4.6 Northstar. So I'm running it without using the oil cooler. The car seems to run a little bit cooler but nothing that the gauge can see. I noticed it in the lower 200s as opposed to 220 and up.
