AUTOMATIC TRANSMISSION AND DIFFERENTIAL
5. THIRD SPEED OF D OR 3 RANGE (D3, 33)
During acceleration, the high clutch is applied and the
input shaft and front planetary carrier are connected.
Further, the forward clutch and one-way clutch (3-4)
operate to connect the front planetary carrier to the
rear internal gear . Power is transmitted from the input
shaft to the rear sun gear and rear internal gear . The
rear sun gear and rear internal gear turn normally at
the same speed. Therefore, the rear planetary carrier,
rear sun gear and rear internal gear rotate normally as
a unit .
" While coasting at "D", because the rear internal gear
turns normally, the one-way clutch (3-4) idles in a
released state . Thus, reverse power is not transmit-
ted to the engine and engine braking action is not
provided .
" During deceleration at "3", "2" or "1st" range, the
overrunning clutch is applied and checks the reverse
rotation of the one-way clutch (3-4). Thus, reverse
power is transmitted to the engine and engine brak-
ing is performed.
