Chronology
Predecessor4G-Tronic
Successor7G-Tronic

5G-Tronic is Mercedes-Benz's trademark name for its 5-speed automatic transmission, starting off with the W5A 580 and W5A 330 (Wandler-5-Gang-Automatik bis 580 oder 330 Nm Eingangsdrehmoment; converter-5-gear-automatic with 330 N⋅m (243 lb⋅ft) or 580 N⋅m (428 lb⋅ft) maximum input torque; type 722.6) as core models.

It 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[a] Mercedes-Benz 7G-Tronic (model W7A 700 · type 722.9) transmission with 11 main components introduced in 2003. Due to its high torque capacity (up to 1,000 N⋅m (738 lb⋅ft)) and lower cost, it was retained for turbocharged V12 engines, 4-cylinder applications and commercial vehicles for almost a decade. It is still being built for niche applications (e.g. Sprinter with petrol/CNG M111 engine, Jeep Wrangler, etc.).
