LSD part numbers ?
 

Does anyone have a quick reference for the LSD part numbers ?

Which part numbers are you looking for?
Transmission ID numbers or Porsche part numbers...
The actual Porsche part number for the LSD differential is 951-332-053-05

However....
In all of my transmission endeavors, I have found that there are 2 distinctly different versions of the LSD in these trannys! The standard LSD (found in many of the factory LSD "option" cars and the Turbos) have 4 round openings on the side of the main diff housing and usually have a much lower locking rate. In the few 944S LSD transmissions that I have opened the differential housing has oval shaped side openings, and locks up MUCH more! I have been told that the regular (round opening diff) is a %40 locker, where as the oval opening diff is an %80. whether this is technically correct or not I can not say, but from my experience you cant get the latter ones to slip by hand! it takes considerable force (or a prybay) to get the plates to slip.

Hope it helps!

Transmission ID numbers is what I wanted...if anyone knows them

Just bought an 87 944S about a month ago. How can you determine if it has LSD or not? Thanks in advance....Jerry

That helped ! Thanks Earl !

Where can I find the option code sticker on my car if it is still on it? Thanks again.

no prob

option sticker should be above the spare tire on the back trunk wall
