[Reaper]

so my roommate how love to argue with walls and people on the internet wants to find out how fast with a stock GM auto shift from WOT to WOT in a vette (ls1 car) and a say Yukon (for contrast)

basicly i think he wants to know so he can call BS on this guy.

the question is how fast in tenth hundredth or thousanth can a GM auto shift gears in WOT conditions.

thanks.
