Trans air cooler vs extra capacity pan

Post by BOOT » Fri Dec 11, 2015 2:52 pm

If you had to choose one over the other what would you do 1st, use a larger pan(lets say 2-4 qrts more) or add an air cooler in addition to already using a cooler in radiator(let say basic small-mid size)?
I know as much as I can learn and try to keep an open mind to anything!

If I didn't overthink stuff I wouldn't be on speedtalk!

Depends what you're doing with it.

Towing? Trans cooler. A bigger oil pan will just make it take longer before it heats up. A trans cooler will actually get rid of more heat.

Drag racing? Flip a coin unless you have additional information about the specific transmission you are using.

my last race car destroyed the planetry and my guy that does my trannys told me in a drag racing application not to use a cooler and just bypass the trans cooler lines between each other,he says that the trans wont get to operating temp quickly enough,a lot different in a street car with a resonable stall converter,deep pan- help carry debris and heat away from internals the same way a larger capacity engine sump if set up correctly.

If you have to "hot lap" it, or if you drive the car on the street, no oil cooler of any sort doesn't sound like a good idea. I have a hard time understanding how having an oil cooler would contribute to destroyed gears inside the transmission.
