I personally have noticed a difference in my transmission trying to shift at 5,500 and at 6,000. I have a reman good-wrench 4L60 and it shifts really great, firm on its own. When i try to shift it at like 6 it gets all sloppy. that is my own personal situation though, cant speak for everyone's trans
I didnt like my
"sloppy" wording as i was specifically referring to when i try to bump the shift myself and it hits rev limiter before shifting. ON ITS OWN it shifts fantastic at 6or below

You can't bump the shift point much higher than stock without raising the rev limiter (stock is 6200rpm), and that's really not a good idea with stock valve springs. Stock shift RPMs are 6,000 for 1-2 and 2-3, and 5900 for 3-4, but Hypertech shift adjustments are done in MPH and I think the range of adjustment is up or down ~6mph. What 1mph equates to in terms of RPM will be dependent on your gear ratio, and there is a little book that comes with the Hypertech that will show a chart of this.
You can probably get away with bumping the 1-2 shift point by 1mph and the 2-3 shift by 2mph without any issues with the rev limiter at the stock setting (6200).
I would leave the shift firmness alone, IMO.
Higher rpm shift points are in fact harder on the trans, but if you're staying within the stock rev limiter then you aren't really raising them high enough to cause much concern beyond expected wear with same-style driving patterns and stock shift points.
