I have an 05 2500HD with the 4l80e/Transgo HD-2 shiftkit with .096 holes in the seperator plate for firm shifts. My 1-2 and 2-3 shifts are fast and firm WOT shifting @ 5600rpms, but my 3-4 is less than stellar under the same condition( and yes I am haulin ass at this point ), what can I do to improve this?

anyone?

in case anyone was wondering what info I found out on this, you can look here, I hope this helps someone else as well:)
