POWER TRANSMISSION 

“N” position

Since both the forward brake and the reverse brake are released, torque from the input shaft drive is not trans-

mitted to the output shaft.

“P” position

•  The same as for the “N” position, both the forward brake and the reverse brake are released, so torque from

the input shaft drive is not transmitted to the output shaft.

• The parking pawl linked with the select lever meshes with the parking gear and fastens the output shaft

mechanically.

“D”, “M5”, “M4”, “M3”, “M2” positions (column shift), “D”, “4”, “3”, “2” positions (floor shift) 1GR

• The forward brake and the forward one-way clutch regulate reverse rotation of the mid sun gear.

• The 1st one-way clutch regulates reverse rotation of the rear sun gear.

• The 3rd one-way clutch regulates reverse rotation of the front sun gear.

• During deceleration, the mid sun gear turns forward, so the forward one-way clutch idles and the engine

brake is not activated.
