They must have changed the shift mechanism on the 03+ trucks or something. Mines an 01 and with bolt ons and a 100 shot I could hit the 2hi button after launching but it just blinks till I let out of it. Many others have had the same xperience, but I dont recall any of the newer trucks having this issue or atleast posting anything about it.
BTW alot of people say it makes a difference not shifting out of 4hi, I tested it back when I just had bolt ons a 3K stall and there wasnt any difference between my times besides my 60fts.
