The Mercedes-Benz 5G-Tronic (also called 722.6) is an electronically shifted 5-speed overdrive automatic transmission with torque converter lockup. It replaced the older 722.3 / 722.4 4-speed 4G-Tronic transmission and its 722.5 5-speed derivative.
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.
A performance feature set for the Mercedes-Benz transmissions, which includes manual mode, active downshifting. When cornering at high speed, the transmission maintains the same gear above a certain lateral acceleration level. It can also automatically downshift before overtaking.
It was first used in 2001 Mercedes-Benz C 32 AMG., 2001 Mercedes-Benz SLK 32 AMG.
A version with mechanical lock-up of the torque converter from first gear, steering-wheel-mounted shifter. AMG Speedshift is also used in 7G-Tronic transmission.
