My transmission feels and sounds like a limited slip. On the bottom of the final drive housing, it is coded 930.33/12 77700441. I believe that 930.33 is the type, and that 77700441 is the year and serial no. (My car is a 77. Also, I am doing this part of the number from memory, so I may be off a digit.) Does the /12 signify a limited slip differential? If it is a limited slip, what is the best oil to quiet it in low speed, tight turns?
Thank you.
Thank you.

The ONLY true way you'll know if you have an LSD is to raise the rear wheels off the ground and spin a tire with the tranny in neutral. If both rear wheels rotate the same direction, you have an LSD,....![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
Use Swepco # 201.
If your LSD is stacked at 80%, it can be noisy and you should have that redone to 40%.
Its all in how the plates are stacked.
