I have ran into issues with my transmission on my 1996 S320 mercedes. I found that my the transmission for my car is a 722.508 and the parts seem to be hard to come by. Does anyone know if the parts on a 722.5 or a 722.6 are interchangeable with the 722.508 transmission. Also does anyone know where I can get reasonable parts for the 722.508 transmission. I am looking for a direct clutch drum, pistions, return springs, and a stator.

Thanks
