[fun in dirt]

I believe about the don't change trans fluid....had a '71 Chevelle in high school. Bought from original owner (70k miles), daily drove year or two, then decided might be a good idea to change trans fluid. My Daddy told me don't do it; I did anyway. 2 weeks later we were putting new trans in it. Had 2004 Chevy 1500 bought new, drove 3 yrs....changed trans fluid & 2 months later it started giving trouble.
