It's just a hard shift. Like as soon as you shift down into 3rd gear or up into 4th it just feels like a jolt and it's done, very common on these transmissions but interestingly enough I noticed when I initially put in 6 quarts into it I noticed that it shifted all very softly. However, I also know that this transmission changes the way it performs over time so anything that's different it will adjust to and potentially perform poorly over (over a long term perspective). I can confirm that based on the way my old set up was overfilled and it absolutely hated it but performed well with it for a very long time despite that until the fluid started getting a little dirty. The change in shifting I felt was more likely than not a temporary false positive.
