General Description
The automatic transmission is a transverse-mounted five-shaft design with an electronically controlled hydraulic circuit that provides six forward speeds and one in reverse. Engine output is transmitted through the torque converter, a combination of shafts which hold gears and clutches and a differential that transmits power to the driving wheels. SH-AWD equipped model also has a transfer assembly which transmits power to the SH-AWD differential.
Gear operation
Gears on the mainshaft
- 3rd gear is engaged/disengaged with the mainshaft by the 3rd clutch.
- 6th gear is engaged/disengaged with the mainshaft by the 6th clutch.
- 4th gear is splined with the mainshaft and rotates with the mainshaft.
Gears on the secondary shaft
- 1st gear is engaged/disengaged with the secondary shaft by the 1st clutch.
- 2nd gear is engaged/disengaged with the secondary shaft by the 2nd clutch.
- 5th gear is engaged/disengaged with the secondary shaft by the 5th clutch.
- Idler gear is splined with the secondary shaft, and rotates with the secondary shaft.
Gears on the third shaft
- 4th gear is engaged/disengaged with the third shaft by the 4th clutch.
- Reverse selector hub is splined with the third shaft and rotates with the third shaft.
- Reverse selector on the reverse selector hub switches between the reverse gear and 6th gear.
Gears on the countershaft
- Final drive gear is integral with the countershaft.
- 2nd gear, 5th gear, and park gear are splined with the countershaft, and rotate with the countershaft.
- 1st gear is engaged with the park gear splined with the countershaft by the one-way clutch when accelerating. It is disengaged from the park gear by the one-way clutch when decelerating.
Gears on the idler gear shaft
- Idler gear is press-fitted with the idler gear shaft, and rotates with the idler gear shaft.
- Idler gear is engaged with the mainshaft 4th gear and the secondary shaft idler gear, and transmits the mainshaft rotation to the secondary shaft.
