1G T-Case Drain Plug Gasket??

[tsi1991awd]

Is there a gasket that goes on the transfer case drain plug? Fluid is leaking out from the drain plug area....same with my rear diff. I have had the fluid changed twice since I have had the car...no idea if there is supposed to be a gasket???

Thanks bro, you always have part numbers for just about everything. Do you know if those parts fit the 1g?

 

[turbosax2]

Yes, they do.

Do you happen to have the P/N for the tranny drain gasket? Its a 91 AWD

Yes, there is.

Rear diff drain plug gasket - MB001294 (18.2mm)

While we are at it.
As far as I can tell these are all crush washers and the same 1g and 2g except for the diff fill.

Transfer case fill plug gasket - MF660036 (16mm)
Manual Transmission drain plug gasket - MD000312 (18.2mm)
Manual Transmission fill plug gasket - MF660036 (16mm)
Automatic Transmission case drain plug gasket - MD000312 (18.2mm)
Automatic Transmission pan drain plug gasket - MD050317 (14mm)
Rear diff fill plug gasket - MF660066 (16mm) changed 1994.10.1 to MF660036

Bringing back an old thread but do the transfer case drain plug gaskets HAVE to be exactly 18.2 mm. Because if I can just use an 18mm crush washer that'd be great .

As long as the crush washer fits over the threads and is not excessively loose, you will be fine.
