    An '85 half-ton should have come with a 700R4. And no, the Turbo 350 doesn't have overdrive. /forums/images/graemlins/shocked.gif

    Yup, you've got the 700R4 - no doubt about it if it's got the O.D. 4th gear. The other two autos offered (TH350 in 1/2 tons and TH400 in 3/4 and 1 tons) have a final third ratio of 1:1. The O.D in the 700's is .70:1 by the way.
    I suggest finding another tranny shop if the guys there said you have a TH350. /forums/images/graemlins/smirk.gif

    Unless it's been swapped out, but still has the 700R gear indicator in it. Can you actually shift into 4 different gears OD D 2 1?

    Well, sorta /forums/images/graemlins/wink.gif.
    700R4 pan is rectangular
    TH400 is the goofy looking thing I can't describe
    TH350 is a rectangle with the corner cut off
