Mercedes-Benz 5G-Tronic transmission

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 and 2001 Mercedes-Benz SLK 32 AMG. 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. It was first used in 2002 Mercedes-Benz E 55 AMG, S 55 AMG, C55, CL 55 AMG. 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. Reduced manufacturing complexity The need of 2 housings and 2 different controls turn out the W5A 030 as the least economically designed automatic transmission ever manufactured for passenger cars. In order to avoid a further increase in manufacturing complexity while expanding the number of gear ratios, Mercedes-Benz switched from the conventional design method—in which the planetary gearset concept was limited to a purely serial or in-line power flow—to a more modern design method that utilizes a planetary gearset concept with combined parallel and serial power flow. This was only possible thanks to computer-aided design. The 5G-Tronic is the 1st generation The 7G-Tronic in 2003 was the first to remedy this situation. As shown in the assessment table below, another drawback of the gearset concept is the significant reduction in speed increase in 5th gear. == Applications ==
