The tranny should be a SM465. As far as gear ratios go, I would guess it would have 4.11's, although you could have 4.56's or 3.73's (I think they were available in the 3/4 tons).

Is there a site that I can go to for this year of truck to look it all up and is the trans a Saginaw or a non gm brand?
