560SL Transmission Rebuild 722.313

I recently completed rebuilding the rear axle.  Since I am this far into the car, I plan on rebuilding the transmission.  The car has 155,00 miles or 249,448 Kilometers.  I am looking for recommendations on sourcing Master rebuild kits.  Mercedes only sells individual parts..........  All suggestions are welcome. 

 

I'm not aware of any Master Conversion Kits available, except for a gasket kit.

I also bought everything in separate parts.

What was the most serious problem you found when rebuilding your ATX?  Did you have to replace any components in the valve body?  Purchasing individual parts can get expensive!
