Snow,
I looked through my magazines (only have half of them since I'm in college) and finally came across some info:
"Skipping Is Not Allowed:
Every model Corvette has its quirks; for C5 performance enthusiasts, the "skip shift" feature has got to be one of the most annoying. Hurst now has a fix wtih its C.A.G.S (Computer Aided Gear Selector) Skip Shift Eliminator. This piece is for '98-01 Corvettes with six-speed transmissions and eliminates the annoying First to Fourth mandatory gear change that occurs under pre-set engine rpm and mph conditions. This allows full First through Sixth gear changes at any speed, rpm, or throttle position for maximum performance acceleration on Corvettes having the Six-speed BW t-56 transmission. It's easily installed and OBD II compatible. Contact the Mr. Gasket Performance Group, 10601 Memphis Ave. #12, Dept. VM, Cleveland, OH 44144; (216) 688 8300,

thats from page 14 of the sept 2002 magazine 'Vette'
from the picture it looks like complete 'plug 'n play' to me. looks like a very simple, quick job, and also appears completely reversible.
good luck
