Between filter changes, I remove and replace ATF using a topsider. By doing this several times, I wind up with about 80% new fluid. When I do this with transmission at operating temp on level ground, I get out about 2.3 quarts.

If the car were pointing downward, would I get slightly more? I just don't have a sense as to where the dipstick tube hits with respect to the fluid. Car is a 91 300D.
