Noticed when I had the Tahoe at my mechanic's shop, that there is a small PS leak. Wiped it down, and will be inspecting it when i do a drivetrain fluid exchange in a month or 2. Since I just bought it, I have no idea what the extent of the leak really is. Anyhow, I'd like to use my Turkey Baster, and exchange some fluid this week. I was thinking of getting a quart of Valvoline Maxlife ATF, and seeing if this would work some magic. I've used ATF on older vehicles, is this still safe to do on a 01 Tahoe? If not, what approaches might you take?
