NOTES
See flushing procedure, page l4-264 and 265,
BSet idle rpm in gear to specified idle speed. lf still no good, adjust motor mounts as outlined in enginesection of this manual.
clf the large clutch piston O-ring is broken, inspect the piston groove for rough machining.
Dlf the clutch pack is seized or is excessively worn. inspect the other clutches fot wear, and check the orificecontrol valves, CPC valve, and linear solenoid for free movement.
lf the linear solenoid is stuck, inspect the clutches for wear.
lf the 1-2 shift valve is stuck closed. the transmission will not upshift. lf stuck open, the transmission hasno lst gear.
Hlf the 2nd orifice control valve is stuck, inspect the 2nd and 3rd clutch Dacks for wear.
lf the 3-4 orifice control valve is stuck, inspect the 3rd and 4th clutch packs for wear.
Jlf the clutch pressure control valve is stuck closed. the transmission will not shift out of lst gear.
Klmproper alignment of main valve body and torque converter housing may cause ATF pump seizure. Thesymptoms are mostly an rpm-related ticking noise or a high-pitched squeak.
Llf the ATF strainer is clogged with particles of steel or aluminum, inspect the ATF pump and differentialpinion shaft. lf both are OK and no cause for the contamination is found, replace the torque converter.
Mlf the lst clutch feed pipe guide in the end cover is scored by the mainshaft. inspect the ball bearing forexcessive movement in the transmission housing. lf oK, replace the end cover as it is dented. The o-rinounder the guide is probably worn.
N' Replace the mainshaft if the bushing for the 4th feed pipe is loose or damaged, lf the 4th feed pipe is darrFaged or out of round. replace the end cover.' Replace the mainshaft if the bushing for the l st feed pipe is loose or damaged. lf the 1st feed pipe is dam-aged or out of round, replace it.
oA worn or damaged sprag clutch is mostly a result of shifting the transmission in E!. E, or E positionwhile the wheels rotate in reverse. such as rocking the vehicle in snow.
PInspect the frame for collision damage.
lnspect for damage and wear:
l. Reverse selector gear teeth chamfers.
2. Engagement teeth chamfers of countershaft 4th and reverse gear.
3. Shift fork for scuff marks in center.
4. Differential pinion shaft for wear under pinion gears.
5. Bottom of 3rd clutch for swirl marks.
Replace items 1, 2, 3. and 4 if worn or damaged. lf transmission makes a clicking, grinding, or whirring noise,also replace mainshaft 4th gear, reverse idler gear, and countershaft 4th gear in addition to 1,2, 3, or 4.lf differential pinion shaft is worn, overhaul differential assembly, replace ATF strainer, and thoroughly cjeantransmission, flush torque converter. cooler, and lines,lf bottom of 3rd clutch is swirled and transmission makes gear noise. replace the countershaft and final drivenoear,
Be very careful not to damage the torque converter housing when replacing the main ball bearing. you
may also damage the ATF pump when you torque down the main valve body. This will result in ATF pumpseizure if not detected. Use the Drooer tools.
SInstall the main seal flush with the torque converter housing. lf you push it into the torque converterhousing until it bottoms out, it will block the fluid return passage and result in damage.

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.
www.emanualpro.com

Thermal Switch Operation l2WD)
During 4WD operation, pressure-regulated fluid is in contact with the clutch piston and the thermal switch.
lf the temperature of the fluid in the differential goes too high, the thermal switch pushes open the relief valve R. This
causes the pressure in the clutch piston to drop, and 4WD mode is disengaged.
THERMAL SWITCHRELIEF VALVE
Reliet Valve Operation
When the fluid pressure goes higher than the relief valve spring force, check valve R opens. Pressure applied at the clutch
piston is held constant. This feature adds stability by preventing the rear wheel drive system from experiencing excessive
to rque.
