These are for a boxster but nearly identical procedure for the 996.

transmission removal


clutch/flywheel/main seal


Caution: with the new PFTE seal (997 101 212 01), according to the WSM, it must be dry fitted (no oil, grease or lubrication). It will destroy the seal.

I'm in the process of developing a RMS seal tool for the DIYers, should be ready in a week or so.

I've just found a later type double lip seal part number 99710121200 will this fit into a 2002 996 where it is advertised it says so,I'm not sure if the local specialist know his stuff.

The original 986 and 996 (first made around 1997) seal has been revised many many times since then..

The latest one I believe is from around 2005-2008ish and is the PTFE seal. Came off the cayenne or cayman if I remember right.

The part number may have been revsied since then, but the seal is the same.

Just be sure to buy the part from a dealer or reputable sources and you will be getting the latest one.

For the 996, this is the latest p/n avialable and the one you should be using.
