nice vid......I thought you were only supposed to lay rubber in 1st with an auto trans....something about it trying to shift while there is resistance against the drive-line instead of JUST the tires sliping......or something...ha ha....I just remember my pops saying something like that when I was in highschool......maybe thats just one of those old man to dumb teenager things.......

any truth to that with th 4l60's VS an older trans with no electronics?

I dont mean to thread jack here....just askin cause that might wear out that 1-2 shift like a sprag in a 400...
