Hi, I know there must have been 1000 posts on this subject, but most of them are for the '99-'02 silverados. My '04 4x4 has what I think is drivetrain lash where I can hear/feel it changing gears from 1st-2nd and 2nd-3rd, and I was wondering if all 4x4's do it or is there anything that can be done about this?

BTW I've already brought the truck in about 2 months ago to get the transmission reprogrammed, or whatever it is they do. It helped on the 1st-2nd shift but not the 2nd-3rd.

Go to an autoparts store and buy some auto tranny conditioner and pour it in. And about 200-300 miles later it should stop.
