Based on all the above comments, a preponderance of other things to do, and the fact that the atf looks so good, I'm going to leave it be. I will check it at 150K and 200K however.

Interestingly, it appears that the FSS computer doesn't see trailer towing as being that severe, even with the occasional 6,000 rpm shifts and cruising in 4th gear (I lock out 5th when towing). On a 1,000 mile trip with the race car in tow, the FSS mileage went down by 1,000; I expected more because of the "severe" driving.

This topic does seem to stir up some spirited discussion!
