the measurement is less than the service limit,
replace the clutch disc.
12. Remove the ring gear holder. 13. Inspect the ring gear teeth for wear and damage.

flywheel for wear, cracks, and burning.
15. Measure the flywheel (A) runout using a dial indicator (B). Through at least two full turns with
pushing against the flywheel each time you turn it
to take up the crankshaft thrust washer clearance. If
the measurement is not within the standard,
replace the flywheel, and recheck the runout; go to
step 16.
16. Install the ring gear holder (A).
17. Loosen the flywheel mounting bolts in a cri sscross
pattern in several steps. Remove the bolts, then
remove the flywheel and the ring gear holder.

14-28Automatic Transmission
System Description
The automatic transmission is a combination of a three-element torque converter and triple-shaft electronically
controlled unit which provides five speeds forward and one in reverse. The entire unit is positioned in line with the
engine.
The torque converter consists of a pump, turbine, and stator assembly in a single unit. The converter housing (pump)
is connected to the engine crankshaft and turns as the engine turns. Around the outside of the torque converter is a
ring gear which meshes with the starter drive gear when the engine is being started. The entire torque converter
assembly serves as a flywheel while transmitting power to the transmission mainshaft. The transmission has three
parallel shafts; the mainshaft, the countershaft, and the secondary shaft. The mainshaft is in line with the engine
crankshaft, and includes the 4th and 5th clutches, and gears for 5th, 4th, reverse, and idler. The mainshaft reverse gear
is integral with the mainshaft 4th gear. The countershaft includes the gears for 1st, 2nd, 3rd, 4th, 5th, reverse, park,
and the final drive. The final drive gear is integral with the countershaft. The countershaft 4th gear and the
countershaft r
everse gear can be locked to the countershaft providing 4th or r everse gear, depending on which way
the selector is moved. The secondary shaft includes the 1st, 2nd, and 3rd clutches, and gears for 1st, 2nd, 3rd, and
idler. The idler gear shaft is located between the mainshaft and the secondary shaft, and the idler gear transmits
power between the mainshaft and the secondary shaft. The gears on the mainshaft and the secondary shaft are in
constant mesh with those on the countershaft. When certain combinations of gears in the transmission are engaged
by the clutches, power is transmitted through the mainshaft, then to the secondary shaft to the countershaft, or
through the mainshaft to the countershaft to provide drive.
The electronic control system consists of the powertrain control module (PCM), sensors, and shift solenoid valves.
Shifting and lock-up are electronically controlled for comfortable driving under all conditions. The PCM is located in
the engine compartment.
The valve bodies include the main valve body, the regulator valve body, and the servo body. They are bolted to the
torque converter housing. The main valve body contains the manual valve, shift valves A, B, C, and E, the relief valve,
the lock-up control valve, the cooler check valve, the servo control valve, and the ATF pump gears. The regulator valve
body contains the regulator valve, the torque converter check valve, the lock-up shift valve, and the 1st and 3rd
accumulators. The servo body contains the servo valve, shift valve D, the accumulators for 2nd, 4th, and 5th, and shift
solenoid valves A, B, C, D, and E. Fluid from the regulator passes through the manual valve to the various control
valves. The 1st, 3rd, and 5th clutches receive fluid from their respective feed pipes, and the 2nd and 4th clutches
receive fluid from the internal hydraulic circuit.
To shift gears, the PCM controls shift solenoid valves A, B, C, D, and E, and A/T clutch pressure control solenoid valves
A, B, and C, while receiving input signals from various sensors and switches located throughout the vehicle. The shift
solenoid valves shift the positions of the shift valves to switch the port leading hydraulic pressure to the clutch. A/T
clutch pressure control solenoid valves A, B, and C regulate their respective pressure, and pressurize the clutches to
engage them and their corresponding gears. The pressure of the A/T clutch pressure control solenoid valves also
applies to the shift valves to switch the port.
The lock-up mechanism operates in D (2nd, 3rd, 4th, and 5th gears). The pressurized fluid is drained from the back of
the torque converter through a fluid passage, causing the torque converter clutch piston to be held against the torque
converter cover. As this takes place, the mainshaft rotates at the same speed as the engine crankshaft. Together with
the hydraulic control, the PCM optimizes the timing and volume of the lock-up mechanism. When shift solenoid valve
E is turned on by the PCM, shift solenoid valve E pressure switches the lock-up shift valve on and off. A/T clutch
pressure control solenoid valve A and the lock-up control valve control the degree of lock-up.

Gear SelectionPosition Description
Automatic Transmission Gear Position Indicator
Shift Indicator and M Indicator
14-29
The shift lever has five positions; P: PARK, R: REVERSE, N: NEUTRAL, D: DRIVE 1st thr ough 5th gear ranges with
D-position automatic shift mode and D-paddle shift mode, S: DRIVE 1st through 5th gear ranges with S-position
automatic shift mode and sequential sportshift mode.
P: PARK Front wheels locked; the park pawl engaged with the park gear on the countershaft. All clutches are released.
R: REVERSE Reverse; the reverse selector engaged with the c ountershaft reverse gear
and the 5th clutch engaged.
N: NEUTRAL All clutches are released.
D: DRIVE
(1st through 5th) General driving; starts off in 1st, shifts automatically to 2nd, 3rd, 4th, then
5th gear, depending on the vehicle speed and throttle position. Downshifts
through 4th, 3rd, 2nd, and 1st on deceleration to stop. The lock-up
mechanism operates in 2nd, 3rd, 4th, and 5th gears.
S: DRIVE
(1st through 5th) S-position
automatic shift
modeFor rapid acceleration at highway speeds and general driving; starts off in
1st, shifts automatically to 2nd, 3rd, 4th, then 5th gear, depending on
vehicle speed and throttle position. Downshifts through 4th, 3rd, 2nd, and
1st gear on deceleration to stop. The lock-up mechanism operates in 2nd,
3rd, 4th, and 5th gears.
Sequential
sportshift mode Manual gear shift driving; vehicle can starts off in 1st and 2nd gears, and
does not upshift automatically.
NOTE: D-paddle shift mode has been added for ’08-09 models.
Starting the engine is possible only in P and N because of a slide-type neutral-safety switch.
The A/T gear position indicator in the gauge control module (tach) shows which shift l ever position has been selected
without having to look down at the console.
When the transmission is switched into the sequential sportshift mode, the shift indicator in the gauge control module
(tach) displays the gear selected, and the M indicator next to the shift indicator comes on. The shift indicator also
displays the gear selected in the D-paddle shift mode, but the M indicator does not come on.
NOTE: D-paddle shift mode has been added for ’08-09 models.
