    Greetings,
    Just got an 85 Blazer to play with. (I hope I don't have to change my name!) The tranny was said to be a rebuild. I would like to know what year it is but I don't know how to id it. I've heard about counting splines on the input shaft or something, but I guess I don't want to know bad enough to tear it down. Anyone know if there are id's built into any of the #'s on the outside of the tranny? Thanks.
    How 'bout a moment of silence for my '89?
    May she rust in peace.

    You could ask the place where it came from if you know where it is. I think they like to start with the later (86-on) because of the improvements made then but it depends on the shop.

    On the passenger side off the transmission to the rear their is a number stamped in something like "6MKM-Y-XXXXXXX-267-A".
    The first digit is the last number off the building year so 6 is 1986, 2 is 1982, 9 is 1989 and so on.

    Hope this will help you.

    Thanks, River. Sad to say, looks like an '85. Got a backup tranny in the old jimmy. Could be worse.
