Transmission Interchangeability


I have a 2012 Mercedes C350 4Matic Coupe VIN WDDGJ8JB1CF902433. Transmission number 722.960 04 049250. Transmission part number from EPC A204 270 15 07. The transmission oil cooler failed, allowing coolant into the transmission, causing a catastrophic failure. I am searching for a suitable used replacement. My question is, when evaluating a used transmission, what are the numbers i should be comparing. For example, there is a used transmission on ebay for sale from a 2014 Mercedes C300. VIN WDDGF8ABXEA953883. Transmission number 722.960 07 764809. Part number from EPC A 204 270 14 06 replaces A 204 270 80 04. Would this transmission be a suitable replacement. Will the valve body need to be replaced to make it work? Is there any other information that would be beneficial to this topic? Thanks in advance for any assistance.

Talk with MB spare-parts, & have all the numbers ready, as they can determine the production-run of that transmission, & let you know if it's a straight swap or not. Plus you'll then have a set-of-transmission-part-numbers to work within.

Now-days, the internals may be used across-the-range, but linkages & wiring harness connexions may catch-you-out.

I don't know a lot about the new transmissions or their designs, but there are a lot of different transmission-fluid types & colors out there. Makes sure you top-up with the correct stuff !

A transmission cooler failure within the radiator does happen, but it's generally a rare event, so bad-luck on that one...There's likely a production fault with the cooler imo, meaning it might happen again. I'd find the biggest after-market air-cooled unit, & by-pass the radiator cooler altogether.

To maintain optimal factory performance and gearing you need to find a 722.960 unit... 

I'm not into the 2012 model so I can't give you exact numbers of units that will work in a pinch, but I know as I swapped earlier and late versions of the 560 and 420 transmissions into my late 560 (which is a 722.350 from the factory) it worked, but I noticed serious gearing differences. Sure, they stil worked and one unit from a 420 even lasted a good little while too (few years)... but the best results came when I found another late model 722.350... Here is a thread I made when in the same situation as you with my W126 Late 560SEL...

While the part numbers in the thread above in no way will work with your 2012, it does provide a map to the sort of interchanging that will be required if you can't find your exact part number on the used market right now... I had to do this a few times while I awaited a good unit in my exact part number to become avialiable at a fair price (usually by buying an entire parts car in distress).
