Hello,
I am currently rebuilding my 722.504 transmission.
The car is a 1996 S124 E280.

Does anyone have a previous experience with discs/plates from a reputable brand as a replacement or is OEM a must?

I am also confused about the 722.5xx variants. I found a valve body that turned out to be from a 722.509 has a part number (A124 270 80 15).
However, as per EPC, the two part numbers for my 722.504 are (A124 270 64 15 & A124 270 79 15). Couldn't find anything online about it but are they interchangeable by any chance?

Thanks
