i think people can believe what they want, but the facts remain:

-tranmission fluid breaks down at high temps, reducing the life of the transmission
-a cooler will reduce these temps and prolong the life of the fluid and therefore the transmission
-the normal operating range is around 170-180, without a cooler (even with one sometimes) the fluid with go over 200.
-you can confirm all of this with a tranny temp gauge

an external filter and cooler will cost you less than $100 (add $40-60 more for a temp gauge). you can install it yourself in a day. you don't have to remove the front bumper assembly (unless you want the cooler in front of the AC condensor) - i put my cooler between the radiator and AC condensor. drill some holes for the filter mount, attach your hoses, fill with fluid, check fluid level and for leaks. i think the most time consuming part for me was running the wire for the gauge. this was my first cooler/filter/gauge install, BTW - its not rocket science.
