F4A4x
The F4A4x series are a series of 4-speed automatic transaxles used by Mitsubishi in a variety of vehicles. They are used in vehicles where the engine [Engine side mount|mounts]] on the left hand side.
All use a 3-element, single stage, two phase torque converter. Gear ratios are the same in all of the F4A4x, with the final drive ratio being modified for each application.
The F4A4x is similar to the F4A51 automatic used in early third generation Magnas.
Compared to earlier Mitsubishi automatic transaxles, the F4A4x:
- Uses a two shaft design instead of three to reduce weight
- Uses metal plates
- Deletes the one-way clutch
- Uses an external oil filter
- Increases oil cooler feed tubes to two, instead of one
