The 722.5 trans was an option on many "euro" versions! IN the USA we only could get that transmission in the W140.032/033 sedan & R129.061/063 roadster.

Is this transmission electronically controlled? Also, can it retrofitted to our US cars? More specifically, those in my signature?

It is a hydraulic control unit. Very similar to the 722.4 transmission except there was an overdrive added in the rear of the transmission.

Overdrive on that trans is computer controlled! You would need A lot of parts to swap that trans into a W124 chassis including a different length driveshaft!

Isn't that the same 5-speed auto (722.5) that was offerred in the EARLY R129 6-cylinder models (e.g., 1990-1993 300SL)?

It is a hybrid hydro-unit with an electronically actuated 5th gear overdrive. Basically an afterthought to the standard 4-speed hydro unit (722.3), to bring the revs down on the roadster's high rear diff (3.69).

The roadster weighs so much, that by only going to a higher diff was the acceleration deemed decent by the public.

Although you would need a custom-length driveshaft (approx. $500), I don't believe the tranny's black-box would be too hard to retro-fit, as long as your got the entire wiring-harness and 1 or 2 sensors, esp. since I don't think it even talks to the CAN.

I've been contemplating this with the 360TE AMG wagon since with a 3.07 and 3.27 diff, the highway revs are TOO high.
