 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 selector lever mes hes with the parking gear and fastens the output shaft
mechanically.
“D1” Position
 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 forwar d, so the forward one-way clutch idles and the engine
brake is not activated.
