Hi all, I have a 91 s-10 blazer 4x4, 4.3 automatic, the problem I am have is
that sometimes 4 lo wont engage and some times it will. I pull the stick
back while in neutral and sometimes I hear this gawd awfull grinding , and
them sometimes it wont grind. Aside from adjusting the shift lever is there
something else I should be looking for.?
