Cooling:
You must have a transmission cooler in your radiator regardless
of what someone has told you for the transmission to last.
Auxiliary coolers are just that, in addition to. Water cools 32
times better (faster) than air always, period. The transmission
fluid comes directly from the torque converter at a much higher
temperature than the water in your radiator and is cooled to the
water temperature fast. Then it goes to the auxiliary cooler to
be cooled far below the water temperature. If you don't need a
cooler in your radiator why does GM spend all that money doing
so? If you wanted to cool a red hot piece of steel fast would
you stick it in water or air, see the point. For the best
cooling you need both water and air cooling for the transmission
to be cooler than the motor.
