Reolacement
!!@ Do not smoke while working on fuel system. Keep open flame away from your work a.ea.
1. Relieve the fuel pressure(seepagell-118).
2. Jack up the vehicle, and support it with jackstands.
3. Remove the drain bolt, and drain the fuel into an approved container.
4. Remove the rear seat (Hatchbackt Remove the spare tire lid and the protective cover), and access panels, and discon-
nect the 2P and 3P connectors.
5. Remove the EVAP two way valve cover and fuel hose protector, and disconnect the connectors.
6. Disconnect the hoses (see page 11-105). Slide back the clamps, then twist hoses as you pull, to avoid damaging them.
7. Place a tack, or other support, under the tank.
8. Remove the strap nuts, and let the straps fall free.
9. Remove the fuel tank.
lf it sticks on the undercoat applied to its mount, carefully pry it offthe mount.
10. lnstallthe drain bolt with a new washer, then coat the drain bolt with Noxrust 1248. Allow the Noxrust to dry tor 20
minutes.
11. Installthe remaining parts in the reverse order of removal.

The automatic transmission is a combination of a 3-element torque converter and triple-shalt electronically controlled
automatic transmission which provides 4 speeds forward and 1 speed reverse. The entire unit is positioned in line with
the engrne.
Torque Converter, Gears, and Clutches
The torque converter consists of a pump, turbine, and stator, assembled in sigle unit. The torque converter is connected to
the engine crankshaft so they turn torether as a unit as the engine turns. Around the outside of the torque convener is a
ring gear which meshes with the starter pinion 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 sub shaft. The mainshaft is in-line with
the engine crankshaft.
The mainshaft includes the 1st, and 2ndl4th clutches,and gear for 3rd, 2nd, 4th, reverse, and 1st. (3rd gear is integral with
the mainshaft, while reverse gear is integral with the 4th gear.)
The countershaft includes the 3rd clutch and gears for 3rd,2nd, 4th, reverse, 1st, and parking. Reverse and 4th gears can
be loched to the countershaft at its center,providing 4th gear or reverse, depending on which way the selector is moved.
The sub-shaft includes the 1st-hold clutch and gears fo 1st and 4th.
The gears on the mainshaft are in constant mesh with those on the countersahft and sub-shaft.When certain combinations
of gears in the transmission are engaged by clutches. power in transmitted from the mainshaft to the countershaft via the
sub-shaft to orovude oil, lo'1. E, E. and E.
Electronic Control
The electronic control svstem consists of the Transmission Control Module (TCM), sensors, and four solenoid valves.
Shilting and lock-up are electronically controlled for comfortable driving under all conditions.
The TCM is located below the dashboard, behind the lelt side kick panel on the driver's side.
Hydraulic Control
The valve bodies include the main valve body, the secondary valve body, the regulator valve body, the serbvo body, and
the lock-up valve body, through the respective separator plates, They are bolted to the torque converter housing,
The main valve body contains the manual valve, the 1-2 shift valve, the 2-3 shitt valve, the Clutch Pressure Control
lCPC) valve, the 4th exhaust valve, the reliel valve, and the ATF pump gears.
The secondary valve body contains the 4-3 kick-down valve, the 3-2 kick-down valve, the 2-3 orifice control valve, the
3-4 shift valve, the orilice control valve, the modulator valve, and the servo control valve.
The regulator valve body contains the pressure regulator valve, the lock-up control valve, the torque converter check
valve, and the cooler check valve.
The servo body contains the servo valve, which is integrated with shift fork shaft, the throttle valve B, and the accumula-
tors.
The lock-up valve body contains the lock-up shift valve and the lock-up timing B valve, and is bolted to the regulator valve
ooqy.
Fluid from the regulator passes through the manual valve to the various control valves.
Shift Control Mechanism
Input to the TCM from various sensors located throughout the car determines which shift control solenoid valve should
be activated. Activating a shitt control solenoid valve changes modulator pressure, causing a shift valve to move. This
pressurizes a line to one ol the clutches, engaging that clutch and its corresponding gear.
Lock-uD Mechanism
In @ position, in 2nd, 3rd and 4th, and @ position in 3rd, pressurized fluid can be drained lrom the back oI the tor-
que converter through a fluid passage, causing the lock-up 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 hydraulic control, the TCM
optimizes the timing of the lock-up mechanism.
The lock-up valves controlthe range of lock-up according to lock-up control solenoid valves A and B, and throttle valve B.
When lock-up control solenoid valves A and B activate, modulator pressure changes. Lock-up control solenoid valves
A and B are mounted on the torque converter housing, and are controlled by the TCM.

Troubleshooting
General Troubleshooting
Check the following before you begin:
o Has the suspension been modified in a way that would affect steering?
. Are tire sizes and air pressure correct?
. lsthe steering wheel original equipment or equivalent?
. ls the power steering pump belt properly adiusted?
. ls steering fluid reservoirtilled to proper level?
. ls the engine idle speed correct and steadyT
Hard steering (check the power assist, see page 17-18. It the torce is over 34 N (3.5 kgf, 7 7 lbf), proceed with this troubl*hooting l

Wheel Alignment
Caster
NOTE: For proper inspection/adjustment of the wheel
alignment check and adjust the following before check-
ing the alignment.
. Check that the susoension is not modified.
. Check the tire size and tire pressure.
. Check the runout of the wheels and tires.
. Check the suspension ball joints. (Hold a wheel with
your hands and move it up and down and right and
left to check tor wobbling.)
Inspection
NOTE: Use commercially-available computerized four
wheel alignment equipment to measure wheel align-
ment {caster, camber, toe, and turning angle). Follow
the equipment manufacturer's instructions.
1. Check the caster angle.
Casler angle: 1'10't 1"
2. lf out of specification. check for bent or damaged
suspension compohents.
