A tranny is not full because you put a certain number of quarts in it. That is an estimate. A tranny is full when the dipstick says so. Your tranny is a little over-full which is not usually a problem.
Yes, I know that. My comment was that I was confident it was not overfilled. Completely drained, changed filter, sealed it up and checked it hot after a short cruise. The "good" side is spot on full, "bad" side shows crazy overfill. Even given the fluid that was retained in the converter, I am sure that the side showing a significant overflow is a false reading.
