Mitsubishi F4A41 F4A42 F4A51 – ATSG (Automatic Transmission Service Group)

This is a four speed, Front Wheel Drive transaxle, with fully electronic controls for the upshifts and downshifts, with 4th gear being overdrive. The individual gear ratios are achieved through two planetary gear sets connected one behind the other. The components of the planetary gear sets are driven or held by means of five multiple plate clutch packs, and some of the later models are equipped with a low sprag.

To minimize fuel consumption, the torque converter clutch is applied by the TCM/PCM, depending on throttle position and vehicle speed. This unit operates very much like the Chrysler 41TE transaxle.

These units are currently found in several Mitsubishi models, Dodge Stratus, some Hyundai models and some Kia models.
