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. Check the inboard boot (A) and the outboard boot (B) on the driveshaft (C) for cracks, damage, leaking
grease, and loose boot bands (D). If any damage is
found, replace the boot and the boot bands.
2. Check the driveshaft for cracks and damage. If any damage is found, replace the driveshaft.
3. Check the inboard joint (E) and the outboard joint (F) for cracks and damage. If any damage is found,
replace the inboard joint or the outboard joint as an
assembly.
4. Hold the inboard joint and turn the front wheel by hand, then make sure the joint is not excessively
loose. If necessary, replace the inboard joint or the
outboard joint as an assembly. 1. Raise the vehicle on a lift.
2. Remove the front wheels.
3. Pry up the locking tab (A) on the spindle nut (B),
then remove the nut.
4. Drain the transmission fluid, then reinstall the drain plug with a new sealing washer:
 5-speed manual transmission (see page 13-5)
 6-speed manual transmission (see page 13-82)
 Automatic transmission (see page 14-232)
5. Remove the nuts and the bolt, then separate the lower arm using a prybar.

2. Remove the right driveshaft (see page 16-4).
3. Remove the three flange bolts, then remove the heat shield.
4. Remove the flange bolt (A) and the two shoulder bolts (B). 5. Remove the intermediate shaft (A) from the
differential. Hold the intermediate shaft horizontally
until it is clear of the differential to prevent
damaging the oil seal (B).

Frequent inhalation of brake pad dust, regardless of material composition, could be hazardous to your health.  Avoid breathing dust particles.
 Never use an air hose or brush to clean brake assemblies. Use an OSHA-approved vacuum cleaner.
Remove, disassemble, inspect, reassemble, and install the caliper, and note these items:
NOTE: Make sure that the caliper pins are installed correctly. Upper caliper pin B and lower caliper pin A are different.
If these caliper pins are installed in the wrong location, it will cause vibration, uneven or rapid brake pad wear, and
possibly uneven tire wear.  Do not spill brake fluid on the vehicle; it may damage the paint; if brake fluid gets on the paint, wash it off immediately with water.
 To prevent dripping brake fluid, cover disc onnected hose joints with rags or shop towels.
 Clean all parts in brake fluid and air dry; blow out all passages with compressed air.
 Before reassembling, check that all parts are free of dirt and other foreign particles.
 Replace parts with new ones as specified in the illustration.
 Make sure no dirt or other foreign matter gets in the brake fluid.
 Make sure no grease or oil gets on the brake discs or pads.
 When reusing brake pads, always reinstall them in their original positions to prevent loss of braking efficiency.
 Do not reuse drained brake fluid. Use only clean Honda DOT 3 Brake Fluid from an unopened container. Using a non-Honda brake fluid can cause corrosion and shorten the life of the system.
 Coat the piston, the piston seal groove, and the caliper bore with clean brake fluid.
 Use recommended greases in the front caliper set.
 After installing the caliper, check the brake hose and line for leaks, interference, and twisting.
Install inner brake pad with
its wear indicator upward.
