|name=5G-Tronic |production=1990–Present |manufacturer=Daimler AG Chrysler Group LLC |class=5-speed longitudinal automatic transmission |predecessor=722.5 & Mercedes-Benz 4G-Tronic transmission | successor = Mercedes-Benz 7G-Tronic transmission }} The Mercedes-Benz 5G-Tronic (also called 722.6) is an electronically shifted 5-speed overdrive automatic transmission with torque converter lockup (typically in gears 3, 4 and 5) and 2-speed for reverse. It replaced the older 722.3 / 722.4 4-speed 4G-Tronic transmission and its 722.5 5-speed derivative. 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, four-cylinder applications and commercial vehicles for many years. It is still being built for niche applications (e.g. 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. SpecificationsGear ratios
Special operating modesWinter ModeActivated by a toggle switch, Winter mode sets the gearbox to start off in 2nd gear, both in Drive and Reverse. This is designed to reduce wheelspin on icy surfaces. Speedshift (2001-)Speedshift is a performance feature set for the Mercedes-Benz transmissions which includes manual mode and 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[3] and 2001 Mercedes-Benz SLK 32 AMG.[4] AMG Speedshift (2002-)A version with mechanical lock-up of the torque converter from first gear and steering-wheel-mounted shifter. AMG Speedshift is also used in 7G-Tronic transmission.[5] It was first used in 2002 Mercedes-Benz E 55 AMG, S 55 AMG, C55, CL 55 AMG.[6] AMG Speedshift RA version used in Mercedes-Benz SLR McLaren. It includes three manual modes. ApplicationsMercedes modelsMercedes S-Class
