Yeah, I was thinking the early S320's also used the 722.5, but I couldn't remember for sure. It was still only used with the M104 engine due to the maximum input torque rating of 300Nm (approx 230 lb-ft). It would work fine with the 606 non-turbo if you could figure out the electronics. A custom driveshaft is also required.



WhippleM104 obtained an aftermarket standalone TCU that makes the 722.6 work in a W124, but it's expensive, and still needs a lot of custom programming to dial it in to the particular engine. It is NOT a simple bolt-in, and the aftermarket controller does not work as well as the factory controller. I am very interested in doing this swap once all the kinks are worked out and the performance equals the factory setup. The 722.6 is really a great transmission and it's strong enough for high power applications (i.e., 6.0L V8's).
