Are you sure it's the tranny shifting from 4th to 3d? Depending on the speed, it
could just be the fuel cutoff system that makes it "feel" like you're downshifting. If you look at your instananeous fuel mileage, it may read 99.9 which indicates no fuel entering the engine. But...... I'd have to see it to be sure.
