Remember, the 1-2 shift (manually) will slow you down unless you shift
before 15mph. When in 1st (L) gear, the reverse band is also applied
and when you shift manually from L to 2, the reverse band releases
rather slowly causing a slight bog on the 1-2 shift.

didn't, the experienced about a .4 loss on their 1/4 mile time. Just
wondering how much of a difference does it really make at the track?
When I run (Automatic, no trans-go, O/D off), truck usually shifts close
to 5000 RPM out of 1st, probably around 4800 out of second, and 3rd is
pretty weak at that point. Wondering if the 1-2-3 shifts manually would
make much of a difference. I've currently run a best of 15.65 in the
1/4, and would be nice to be able to run a low 15. Think I just opened
up a big can of worms here :-)

Your 1-2 shift sounds pretty good. If your rev limiters have been moved
up, I'd try the 2-3 manually, maybe 5400, some guys are going higher,
depends on your setup. But with your truck shifting at 4800 I'd think
that there's some time to be had there.
