Itself, it was replaced by the Mercedes Benz 7G-Tronic 722.9 transmission introduced in 2003. This turned out to be a very lengthy process stretching out over nearly a decade. Due to its high torque capacity (up to 1000 Nm) and lower cost, it was still retained for turbocharged V12 engines respectively four-cylinder applications and commercial vehicles for many years. It is still being built for niche applications (Sprinter with gasoline/CNG M111 engine, Jeep Wrangler etc.)
In Chrysler applications this transmission is identified as the New Automatic Gearbox Generation One, or NAG1.
