Transmission compatibility
Hello all, in need of some help. I'm curious what's the difference is between the 722.931 and 722.930 transmissions? My 2012 E63 has a 722.931 transmission in it and I have an opportunity to buy a built 722.930 transmission. Would I be able to swap it in as long as I swap over the valve body and conductor plate or is there more to it? The donar car is a 2017 C63. I know the VGS are different, mine being a VGS 3 and donar being a VGS 4 will that be a physical issue or just security reasoning? Thanks!

The likelyness this is going to plug and play are slim.
Moving your VGS3 over to new box is more likely if it's a bolt on match. Rebuilding your original is the sure way to no headaches.

I guess what I'm asking is will I have drivability issues if I swapped in the 722.930 and transfer over all the electricals from the 722.931 transmission?

Go to www.lastvin.com and enter your VIN. Look to see if you have code A89 REDUCED-FRICTION. If you do, then you know the AI is lying to you. You want to make sure you use the blue tranny fluid (236.15).

Have you tried your local Mercedes dealership and asked if you can install the 733.930? I think I would keep everything together and just have the dealer recode the car. BenzNinja says you would need to have the TCU “virginized” first (on a bench) and then programmed for your car.

Well, you have options. Try it one way first. If that doesn't work, try it the other way.
I had a 2004 SL500 with one of the first 7G trannies. At one time, I had to replace the conductor plate. Because it is a theft part, you can only get it from the dealer and they must install and configure it.
You should find a good independent shop that specializes in Mercedes. Most dealers are just retailers and not enthusiasts.
