    I am looking for the paper gasket that is sandwhiched between my SM465 and the adapter for the transfer case (205, figure 8 pattern).

    None of the parts stores can figure out how to look it up and always just suggest some RTV.

    So I used a bead of RTV around the entire perimiter this last weekend during a clutch job...and I now leave a little trail (of gear oil) everywhere I drive. I swear it might be as bad as a 1/2 pint a day.

    Has anyone else run into this problem? (of not finding the gasket)

    -I used RTV #2 (non-hardening) gasket maker.
    -I found this one Checker's website. http://www.partsamerica.com/productdetail.aspx?MfrCode=SKF&MfrPartNumber=13676&PartType=1340&PTSet=A
    The picture is obviously a generic one. If you have my vehicle plugged in it will come up with the description
    If the adapter is the same on both ends, then I assume the gasket would be the same as well. I have only had the tranny and adapter apart (not the adapter and transfer case) so I don't know for sure.

    If I can't find the actual gasket somwhere would my second best option be to buy a sheet of gasket material and cut out the pattern I need? Or try again with RTV, perhaps a different kind of RTV?

    I got one for my TH400/208 from the local transmission shop, as the parts houses couldn't figure it out either. I tried RTV without the gasket and got a prodigious leak.

    I note mine is just paper, so you could prolly do it by hand from, as you say, gasket material ... wouldn't go so far as to use cork, but...

    yeah the cereal box idea actually works fairly well. I dont know why straight rtv doesnt work, it does a great job on diff covers.

    gm dealer is the best/only(?) place to get that gasket.
    the part number is 8672160 $6.49 each.
    i ordered 2 incase i needed to pull the adapter and couldn't wait for it to show up.

    FYI, if you order it from gmpartsdirect.com, its only about 3.50 but $10 for shipping, not worth it IMO.

    Is it the same gasket for both sides of the adapter?

    no, the np205 has a kickout on one side to clear a shaft or something. those come in a 5 pack. not sure of the part number, but its in the part number post in the advanced previews forum.

    Don't go the right place the first time-(Dealership).. The dealer has OEM parts- the parts the vehicle was engineered & built with... If I were you I'd do like the other dude said and make a gasket out of a cereal box. Gota use a Lucky Charms box though. Those seal up the best.

    This has been covered a few times. That gasket sets clearance between the adapter and the lower bearing on the 465.
