    3/4 ton should be a 4L80, 1/2 ton would be a 700R4.

    When were the 4l80 put in the Burbs? I thought they didn't come into play until the body change in '92.

    The 4L80 was put in the 91's. If it's 6-lug, it should be a 700.

    A 91 would be 4l80e if it's 3/4 ton 8 lug and 4l60e if it's 6 lug.

    If its a 91 4x4 3/4 ton, it may have the rare 4L80e to np205 adapter.
