AUTOMATIC TRANSMISSION AND DIFFERENTIAL [nn2oA4] 3- 2
4. SECOND SPEED OF D, 3 OR 2 RANGE (D2, 32,
22)
During acceleration, the forward clutch is applied and
connects the front planetary gear to the internal gear
through the one-way clutch (3-4). Power is transmit-
ted from the input shaft to the rear sun gear, turning
the rear planetary carrier (i .e . front internal gear).
Also, since the band brake is applied and the front
sun gear is locked, the rear internal gear turns nor-
mally through the front planetary carrier and the
forward clutch and one-way clutch (3-4) that are
connected to that carrier . Thus, speed increases in
proportion to the rotation of the rear internal gear
compared with the first speed .
Since the rear internal gear turns normally while
coasting, the one-way clutch (3-4) is released and
idles. Accordingly, reverse power is not transmitted
to the engine and engine braking is not provided .
" During deceleration at "2" range, the overrunning
clutch operates to check idling of the one-way clutch
(3-4) . Reverse power is transmitted to the engine,
providing engine braking action .
