I assume that it means something akin to "Automatic Gearbox," auf Deutsch.

So, it is a generic term. Thank you.

More specifically, does the above trans have transmission overload protection/relay and could rough shifting be attributed to this or should I look elsewhere first. All but working pressure has been checked, fluid is perfect, trans only shifts smooth when very warmed up/15 minutes on the freeway. Thanks for the help. Michael

722.4xx is a hydromechanical transmission. There are no electrical parts involved.

Rough shifting is likely a bad modulator, disconnected modulator, or bad or misadjusted Bowden cable.

Thanks Matt. I didn't think so. Best, Michael

In this case, Automatik Getriebe. A manual is a Schaltgetriebe
