Variants 4-speed longitudinal automatic transmissions

  • 722.3 (W4A040)
  • 722.4 (W4A020)

Mercedes Benz 722.3 722.4 TransmissionsIt's a hydraulically operated non-lockup four speed automatic that replaced the similarly designed 722.0, 722.1 and 722.2 family of automatic transmission in 1981. Its calibrated to take off in second gear to reduce "creeping" and provide a smoother ride. The transmission will select 1st only if the selector is in "2" or in case of abrupt acceleration. Other attributes of this transmission include a 2-3 shift delay when the engine is cold in order to speed up catalyst warm-up. 4th gear is a 1:1 ratio. The 4G-Tronic is considered by enthusiasts to be one of the most reliable transmissions ever built by Mercedes-Benz with some examples exceeding 300,000 miles of service.

The 4G-Tronic was used until mid-1996 in some vehicles when it was replaced by the Mercedes-Benz 722.5 which is basically the same transmission with an additional electrically controlled 5th gear for overdrive. This was in turn replaced with the more modern 5G-Tronic (722.6) transmission that features a torque converter lockup and fully electronic control.
