Lock-up Mechanism
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.

1. Connect the HDS to the DLC (A) located under the
driver’s side of the dashboard.
2. Turn the ignition switch to ON (II). Make sure the HDS communicates with the PCM. If it does not, go
to the DLC circuit troubleshooting (see page
11-204).
3. Select Shift Lock Solenoid Test in the Miscellaneous Test Menu, and check that the shift
lock solenoid operates with the HDS.
4. Check that the shift lever can be moved out of P when Shift Lock Solenoid is ON. Move the shift
lever back in P, and check it locks when Shift Lock
Solenoid is OFF.
5. Check that the shift lock releases when the shift lock release is pushed, and check that it locks when
the shift lock release is released.
6. If the shift lock solenoid does not work properly, go to the shift lock system troubleshooting (see page
14-280). NOTE: Make sure not to get any silicone grease on the
terminal part of the connectors and switches, especially
if you have silicone grease on your hands or gloves.
1. Remove the shift lever assembly (see page 14-254).
2. Remove the shift lock solenoid connector.
3. Release the shift lock solenoid lock (A), then remove the shift lock solenoid (B).
