    Somewhere during this build I lost the transmission dipstick & tube. Will any advertised aftermarket GM 400 dipstick & tube work & be accurate or does the Buick thm400 w/sp require a special unit.
    Thanks Al T.

    it's not a sp. specific tube and stick, but a tube for a chevy will not fit properly

    Thanks Ben. Is the problem with the fit where the tube mounts to the trans or a stick length issue or something else that can be modified ???

    It would be where it's secured to the block/bellhousing.

    Any TH400 equipped Olds 65 -79 dipstick assembly should work. I
    prefer the late 70s style with the trans funnel style rubber gasket. Bruce Roe

    correct the location of the top bolt on a box and chevy are different so the tubes will not directly interchange without some massaging
