Power Transmission

"N" position

Since both the forward brake and the reverse brake are released, torque from the input shaft drive is not transmitted 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) 1st Gear

• 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.

"M1" position (column shift), "1 " position (floor shift) 1st Gear

• The front brake fastens the front sun gear.
• The forward brake and the forward one-way clutch regulate reverse rotation of the mid sun gear.
• High and low reverse clutch connects the rear sun gear and the mid sun gear.
• The low coast brake fastens the mid sun gear.
• During deceleration, the low coast brake regulates forward rotation of the mid sun gear and the engine brake functions.

"D", "M5", "M4", "M3" positions (column shift), "D", "4", "3" positions (floor shift) 2nd Gear

• The forward brake and the forward one-way clutch regulate reverse rotation of the mid sun gear.
• The 3rd one-way clutch regulates reverse rotation of the front sun gear.
• The direct clutch is coupled and the rear carrier and rear sun gear are connected.
• During deceleration, the mid sun gear turns forward, so the forward one-way clutch idles and engine brake is not activated.
