I have for sale a CD ROM containing the complete repair, teardown and adjustment for the 722 series transmissions. If the first four digits of your transmission are 722.3 then this manual is the one you need. This is the most popular transmission for W126 and W124 bodies. I am sking $50 for it shipping included. Email me at greekboy005@hotmail.com.

P.S. I also have a used 722.320 transmission for sale that works great. Contact me if you need info on it.
