I did the TSS swap last week & it cured all sorts of irritating behavior in my tranny. I had the bang shift & the rest of the driving range felt a little "loose" - just generally sloppy. Took me a whopping 3 minutes & I didn't have to remove the front wheel, just cut em hard left & parked it.
Now I get smooth shifts, the rest of the driving range is much tighter & more refined. I had originally installed a superchip to try to fix some of these problems & its effect was minimal, though it did change my shift points to a much better range.

(sorry, ramblin')
