When the PCM determines that the vehicle is climbing a hill in D, and S with automatic shift mode, the system extends
the engagement area of 2nd, 3rd, and 4th gears to prevent the transmission from frequently shifting between 2nd and
3rd gears, between 3rd and 4th gears, and between 4th and 5th gears. Then PCM does this so the vehicle can run
smoothly and have more power when needed.
NOTE: Shift commands stored in the PCM between 2nd and 3rd gears, between 3rd and 4th gears, and between 4th
and 5th gears, enable it to automatically select the most suitable gear according to the magnitude of a gradient.
When the PCM determines that the vehicle is going down a hill in D, and S with automatic shift mode, the upshift
speed from 4th to 5th gear, from the 3rd to 4th gear, and from 2nd to 3rd gear (when the throttle is closed) becomes
higher than the set speed for flat road driving to extend 4th gear, 3rd gear, and 2nd gear driving area. This, in
combination with engine braking from the deceleration lock-up, achieves smooth driving when the vehicle is
descending. There are three descending modes with different 4th gear driving areas, 3rd gear driving areas, and 2nd
gear driving areas according to the magnitude of a gradient stored in the PCM. When the vehicle is in 5th gear or 4th
gear, and you are decelerating when you are applying the brakes on a steep hill, the transmission will downshift to
lower gear. When you accelerate, the transmission will then return to a higher gear.

Î Shift Control - Manual Shift Mode
D-Paddle Shift Mode
14-43
SHIFT INDICATOR
The transmission is provided with a D-paddle shift mode in D, and with a sequential sportshift mode in S. Both modes
are entered by pressing the paddle shifter (upshift switch) or the paddle shifter (downshift switch) while driving.
When the transmission is switched into the D-paddle shift mode by pressing the paddle shifters while driving in D, the
transmission can shift into a lower gear by pressing the paddle shifter (downshift switch), and it can shift into a
higher gear by pressing the paddle shifter (upshift switch). When the transmission shifts into a lower gear or a
higher gear by pressing the paddle shifters, the shift indicator in the gauge control module (tach) displays the number
of current gear selected. This number of the gear goes off when the transmission downshifts automatically, or when
the transmission upshifts automatically while coasting.
The transmission stays in 5th gear if the paddle shifter (upshift switch) is pressed when driving in 5th gear, and the
shift indicator displays ‘‘5’’ for 2 seconds, then goes off. The transmission stays in 1st gear if the paddle shifter is
pressed when driving in 1st gear, and the shift indicator displays ‘‘1’’ for 2 seconds, then goes off.
The transmission stays in the current gear and does not upshift to the next higher gear if the paddle shifter is
pressed while driving below the minimum allowable speed, and the shift indicator blinks the number of the next
higher gear several times, then returns to the number of the current gear.
NOTE: D-paddle shift mode has been added for ’08-09 models.

The PCM turns shift solenoid valve A ON, B and C remain ON, and D and E remain OFF. Shift solenoid valve A
pressure (SA) is applied to the right side of shift valve A. Shift valve A is moved to the left side to uncover the line
pressure port leading to the 1st clutch, and to cover the A/T clutch pressure control solenoid valve pressure port.
Fluid flows to the 1st clutch by way of:
Line pressure (1) Shift valve D Line pressure (1A) Shift valve A Line pressure (1B) Manual valve Line
pressure (5A) Shift valve C Line pressure (5B) Shift valve B 1st clutch pressure (10) 1st clutch
The 1st clutch pressure (10) is applied to the 1st clutch, and the 1st clutch is engaged securely.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

As the speed of the vehicle reaches the programmed value, the PCM turns shift solenoid valve A OFF, B and C remain
ON, and D and E remain OFF. Shift solenoid valve A pressure (SA) in the right side of shift valve A is released. Shift
valve A is moved to the right side uncovering the A/T clutch pressure control solenoid valve A and B pressure port
leading to the 1st and 2nd clutches. The PCM actuates the A/T clutch pressure control solenoid valve to regulate
hydraulic pressure. A/T clutch pressure control solenoid valve A pressure (55) changes to 1st clutch pressure (10) at
shift valve B. A/T clutch pressure control solenoid valve B pressure (56) changes to (5E) at shift valve C and to (5F) at
shift valve B, and becomes 2nd clutch pressure (20) at shift valve A. The 1st and 2nd clutches are engaged gently.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

shift valve B, and becomes 3rd clutch pressure (30) at shift valve A. The 2nd and 3rd clutches are engaged gently.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

The PCM turns shift solenoid valves B and D OFF, A and E remain OFF, and C remains ON. Shift solenoid valve B
pressure (SB) in the right side of shift valve B is released, and shift valve B is moved to the right side. Shift solenoid
valve D pressure (SD) in the left side of shift valve D is released, and shift valve D is moved to the left side. This valve
movement causes A/T clutch pressure control solenoid valve C pressure port leading to the 3rd clutch.
A/T clutch pressure control solenoid valve C pressure (57) changes to (5J) to be directed to shift solenoid valve D and
to (5K) at shift valve B, and becomes 3rd clutch pressure (30) at shift valve A. 3rd clutch pressure (30) is applied to the
3rd clutch, and the 3rd clutch is engaged securely.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

As the speed of the vehicle reaches the programmed value, the PCM turns shift solenoid valve C OFF, and A, B, D, and
E remain OFF. Shift solenoid valve C pressure (SC) in the right side of shift valve C is released. Shift valve C is moved
to the right side uncovering the A/T clutch pressure control solenoid valve B and C pressure ports leading to the 3rd
and 4th clutches. The PCM actuates the A/T clutch pressure control solenoid valves to regulate hydraulic pressure. A/T
clutch pressure control solenoid valve C pressure (57) changes to 3rd clutch pressure (30) at shift valve A. A/T clutch
pressure control solenoid valve B pressure (56) changes to (5G) at shift valve C, and becomes 4th clutch pressure (40)
at shift valve B. The 3rd and 4th clutches are engaged gently.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.
