The power flow when decelerating is as follows:
Rolling resistance trom the road surface goes through the tront wheels (and rear wheels: 4WD) to the final drive gear.
then to the sub-shaft lst gear via the 4th gear. and 1st-hold clutch which is applied during deceleration.
The one-way clutch is free because the application of torque is reversed.
The counterforce conveyed to the countershaft 4th gear turns the sub-shaft 4th gear via the mainshaft 4th gear. Since
hydraulic pressure is also applied to the 1st clutch. counterforce is also transmitted to the mainshaft. As a result,
engine braking can be obtained with'lst gear.
NOTE: The illustration shows the 4WD automatic transmission; power flow of the 2WD automatic transmission is identi-
cal to the 4WD except tor parts related to the transfer assembly.

Description
Rear Differential
Outline
The Real-time 4WD-Dual Pump System model has a hydraulic clutch and a differential mechanism in the rear differential
assembly. Under normal conditions, the vehicle is driven by the front wheels. However, depending on to the driving force
of the front wheels and the road conditions. the system instantly transmits appropriate driving force to the rear wheels
without requiring the driver to switch between 2WD (tront wheel drive) and 4WD (four wheel drive). The switching mecha-
nism between 2WD and 4WD is integrated into the rear differential assembly to make the system light and compact.
ln addition, the dual-pump system switches off the rear-wheel-drive force when braking in a forward gear. This allows the
braking system to work properly on models equipped with an Anti-lock Braking System (ABS).
Construction
The rear differential assembly consists of the torque control differential case assembly and the rear differential carrier
assembly. The torque control differential case assembly consists of the differential clutch assembly, the companion
flange, and the oil pump body assembly. The rear differential carrier assembly consists of the differential mechanism. The
differential drive and driven gears are hypoid gears.
The oil pump body assembly consists of the front oil pump, the rear oil pump, the hydraulic control mechanism, and the
clutch piston. The clutch piston has a disc spring that constantly provides the differential clutch assembly with a preset
torque to Drevent abnormal sound.
The clutch guide in the differential clutch assembly is connected to the propeller shaft via the companion flange, and it
receives the driving force lrom the transfer assembly. The clutch guide rotates the clutch plate and the front oil pump in
the oil pump body.
The clutch hub in the differential clutch assembly has a clutch disc that is splined with the hypoid drive pinion gear. The
hypoid drive gear drives the rear oil pump.
The front and rear oil pumps are trochoidal pumps. The rear oil pump capacity is 2.5 percent larger that the front oil pump
to handle the rotation difference between the front and rear wheels caused by worn front tires and tight corner braking.
The oil pumps are designed so the fluid intake works as a fluid discharge when the oil pumps rotate in reverse. Genuine
Honda CVT fluid is used instead of differential fluid.
Operation
When there is a difference in rotation speed between the front wheels (clutch guide) and rear wheels (hypoid driven gear),
hydraulic pressure from the front and rear oil pumps engages the differential clutch, and drive force from the transler
assembly is applied to the rear wheels.
The hydraulic pressure control mechanism in the oil pump body selects 4WD mode when the vehicle is started abruptly,
or when accelerating in a forward or reverse gear (causing rotation difference between the front and rear wheels). or
when braking in reverse gear {when decelerating). lt switches to 2WD mode when the vehicle is driven at a constant speed
in forwar! or reverse gear (when there is no rotation difference between the front and rear wheels), or when braking in a
fo rwa rd gear (when decelerating).
To protect the system, the differential clutch assembly is lubricated by hydraulic pressure generated by the oil pumps in
both 4WD and 2WD modes. Also, the thermal switch relieves the hydraulic pressure on the clutch piston and cancels 4WD
mode if the temDerature of the differential fluid rises above normal.

SUPPLEN\EN AL RES\RA(N SYSTES{ (SRS\
This model has an SRS which includes a driver's airbag in the steering wheel hub. a passenger's airbag in the dashboardabove the glove box ('97 - 00 models), and seat belt tensioners in the seat belt retractors ('98 - 00 models). Informationnecessary to safely service the SRS is included in this Service Manual. ltems marked with an asterisk (*) on the contentspage include, or are located near, SBS components. Servicing. disassembling or replacing these items will require specialprecautions and tools, and should only be done by an authorized Honda oearer.
To avoid rendering the SRS inoperative, which could lead to peFonal iniury or death in the event of a sevore trontalcollision. allSRS service work must be performod by an authorized Honda dealer.lmproper service procedurgs, including incorrect removal and installalion of the SRS, could lead to personal iniurycaused by unintontional deployment of th€ airbags {'97 - 00 models), and seat belt tensioners ('98 - 00 modelsl.Do not bump the SRS unit. Otherwise, the system may lail in case ot a collision, or the airbags may deploy when theignition switch is ON (lll.
SRS electrical wiring harnesses are identitied by yellow colof coding. Ralated components are located in the steeringcolumn, front console, dashboard, dashboard lower panel, and in the dashboard above the glove box. Do not use elec-trical test equipment on these cilcuits,

Removal
SRS components are located in this area. Review the
SRS component locations, precautions, and procedures
in the SRS section (24) before performing repairs or ser-
vice.
1. Align the front wheels straight ahead. then remove
the driver's airbag assembly (see section 24) from
the steering wheel.
2. Disconnect the horn connector and cruise control
switch connectors.
CONTROLSWITCHES CONNECTOR
3. Loosen the steering wheel bolt, then install a steering
wheel puller on the steering wheel and remove it.
Note these items when removing the steering wheel:
. Do not tap on the steering wheel or the steering
column shaft when removing the steering wheel.
. lf you thread the puller bolts into the wheel hub
more than five threads, the bolts will hit the cable
reel and damage it. To prevent this, install a pair
of jam nuts five threads up on each puller bolt.

Knuckle/Hub Replacement
Note these items during replacement:
. Replace the selt-locking nuts after removal.
. The vehicle should be on the ground before any bolts or nuts connected to rubber mounts or bushings are tightened.
. Torque the castle nuts to the lower torque specifications, then tighten them only far enough to align the slots with each
pin hole. Do not align the nuts by loosening.
o Use only genuine Honda wheel weights for aluminum wheels. Non'genuine wheel weights may corrode and damage
the aluminum wheels.
. Onthealuminum wheels, remove the center cap from the inside of the wheel after removing the wheel.
. Before installing the brake disc, clean the mating surfaces of the front hub and brake disc.
. Before installing the wheel. clean the mating surfaces ofthe brake disc and wheel.
. Wipe off the grease before tightening the nuts at the balljoints.
