Preparing for a 1000 mile trip - no relation to 2000 mile trip thread

[Ryan]

Hey guys and gals. I'm about to purchase Bwana's pearl white 1994 SVX this weekend. I will be driving it back from Illinois to Massachusetts. Fortunately we're in the northern part of the US so outside temps should be friendly. The tranny is 22k old with no special filters or ATF cooler (yet). The drive should be about 1000 miles and Mapquest says 14 hours. I won't be able to change the fluids or prep the car before I start the trip so I have a few questions.

I am breaking the trip into two days, 500 miles each (about 8-10 hours if traffic is bad). Is it worth it to stop every 100 miles and let it cool for a half hour, or should I just get the 500 miles done in one fowl swoop? Will the tranny cool enough during the half hour or will I be wasting my time? Any input is appreciated. Thanks!
