Successor	7G-Tronic

5G-Tronic is the unofficial name given by car enthusiasts to Mercedes-Benz's 5-speed automatic transmission type 722.6 for longitudinal engines. It was produced from 1996 to 2020 in different variants as converter-5-gear-automatic transmission (German: Wandler-5-Gang-Automatik). The core models W5A 330 and W5A 580 are for engines up to 330 N⋅m (243 lb⋅ft) or 580 N⋅m (428 lb⋅ft) maximum input torque. The W5A 280 and W5A 300 were built for vans and SUVs, the W5A 400 for off-road applications (RWD and 4X4), and the W5A 900 (up to 1,000 N⋅m (738 lb⋅ft)) for V12-applications.

History

This fourth-generation transmission by Mercedes-Benz replaced the older 4-speed 4G-Tronic transmission-family and its 5-speed derivative, and was replaced by the much more complex and costly 7-speed Mercedes-Benz 7G-Tronic transmission (model W7A 700 · type 722.9) introduced in 2003. Due to its high torque capacity and lower cost, it was retained for turbocharged V8 and V12 engines, 4-cylinder applications and commercial vehicles for almost a decade. Production ended in 2020 with niche applications like Sprinter with petrol/CNG M111 engine and Jeep Wrangler.

Specifications

Winter/summer (standard) mode

Activated 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. Also in "W" mode the transmission will shift at lower speeds. "S" mode is not sport but Sommer (German for summer) or Standard.

With Jaguar XJR applications the switch is labeled "Sport." In regular driving mode the gearbox starts off in 2nd gear, both in Drive and Reverse, and will only engage 1st gear when triggered via the kickdown switch (Drive only). While "Sport" mode is enabled the gearbox will always start off in 1st gear.

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^[4] and 2001 Mercedes-Benz SLK 32 AMG.^[5]

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.^[6]

It was first used in 2002 Mercedes-Benz E 55 AMG, S 55 AMG, C55, CL 55 AMG.^[7]

AMG Speedshift R

A version used in Mercedes-Benz SLR McLaren. It includes three manual modes.

Planetary gearset concept

Improved fuel economy

The 5G-Tronic is an electronically shifted 5-speed overdrive automatic transmission with torque converter lock-up, typically in gears 3, 4 and 5.

The main objective in replacing the predecessor model was to improve vehicle fuel economy with extra speeds and a wider gear span to allow the engine speed level to be lowered (downspeeding), which is a decisive factor in improving energy efficiency and thus reducing fuel consumption. In addition, the lower engine speed level improves the noise-vibration-harshness comfort and the exterior noise is reduced.
