If the transmission jumps out of gear during deceleration, inspect the components that may allow for the gears or shafts to tip. If the gears or shafts tip, the synchronizer sleeve can disengage from the selector teeth on the speed gear. If the transmission jumps out of gear during acceleration, inspect the components that may not allow full engagement of the synchronizer sleeve to the selector teeth on the speed gear. Insufficient engagement of the selector teeth under torque may cause the transmission to jump out of gear. Test Description The numbers below refer to the step numbers on the diagnostic table. 2. A static shift test is performed by shifting into all gear positions with the engine not operating. While performing the test, slowly move the shift lever. Feel for proper movement of the shift lever and transmission internal shift components. 4. A dynamic shift test is performed by shifting into all gear positions with the engine operating. Test for the correct mesh of the synchronizers sleeve and the speed gear selector teeth. Move the shift lever, and feel for the synchronizer sleeve to release from the gear, then let up on the clutch pedal. Depress the clutch pedal and move the shift lever to engage the gear again, to ensure full travel of the shift components. 5. This step inspects for worn or damaged transmission or engine mounts. Loose mounts may cause a shock on the transmission allowing for gear disengagement. 6. This step inspects for the misalignment of the torque tube to transmission. Misalignment may put a bind on the input shaft, allowing for the input shaft or the mainshaft to tip. 8. This step inspects the pilot bearing and the pilot bearing journal on the input shaft. A worn pilot bearing or input shaft may allow the input shaft to tip, causing gear disengagement.

REMOVE TRANSAXLE FROM ENGINE 2. REMOVE CLUTCH COVER AND DISC a. Align the matchmark on the clutch cover with the one on the flywheel. b. Loosen each set bolt one turn at a time until spring tension is released. c. Remove the set bolts, and pull off the clutch cover with the clutch disc. NOTICE: Do not drop the clutch disc. 3. REMOVE RELEASE BEARING AND FORK FROM TRANSAXLE Remove the release bearing with the fork together and then separate them. 4. REMOVE RELEASE FORK SUPPORT AND BOOT INSPECTION 1. INSPECT CLUTCH DISC FOR WEAR OR DAMAGE Using vernier calipers, measure the rivet head depth. Minimum rivet depth: 0.3 mm (0.012 inch) If necessary, replace the clutch disc. 2. INSPECT CLUTCH DISC RUNOUT Using a dial indicator, check the disc runout. Maximum runout: 0.8 mm (0.031 inch) If necessary, replace the clutch disc runout. 3. INSPECT FLYWHEEL RUNOUT Using a dial indicator, check the flywheel runout. Maximum runout: 0.1 mm (0.004 inch) If necessary, replace the flywheel. Torque: 1st: 49 Nm ( 00 kgf-cm, 36 ft. lbs.) 2nd: Turn 90° 4. INSPECT DIAPHRAGM SPRING FOR WEAR Using vernier calipers, measure the diaphragm spring for depth and width of wear. Maximum: A (Depth): 0.5 mm (0.020 inch) B (Width): 6.0 mm (0.236 inch) If necessary, replace the clutch cover. 5. INSPECT RELEASE BEARING Turn the bearing by hand while applying force in the axial direction. HINT: The bearing is permanently lubricated and requires no cleaning or lubrication. If necessary, replace the release bearing. INSTALLATION 1. INSTALL CLUTCH DISC AND CLUTCH COVER ON FLYWHEEL

SYMPTOM A squealing or moaning noise is heard from the rear of the vehicle when the front tires are slipping during acceleration or when the vehicle is turning. PROBABLE CAUSE Water entered the differential through the breather tube and contaminated the differential fluid. CORRECTIVE ACTION Flush the differential with new fluid and/or replace the differential clutch set. PARTS INFORMATION Breather Tube Assembly: P/N 41130-P6R-020 Differential Clutch Set: P/N 48010-P6R-305 Rear Differential Mounting Bracket: P/N 50710-S10-A01 Honda Dual Pump Fluid: P/N 08200-9002 DIAGNOSIS 1. Test-drive the vehicle on a dirt or gravel road. From a stop, accelerate hard to make the front tires slip. • If the rear differential makes noise, go to the REPAIR PROCEDURE. • If the rear differential does not make noise, go to step 2.2. Test-drive the vehicle in a circle on a paved, open parking lot at about 10 mph while holding the steering wheel in a full-lock position. • If the rear differential makes noise, go to the REPAIR PROCEDURE. • If the rear differential does not make noise, disregard this bulletin and troubleshoot other causes. REPAIR PROCEDURE 1. Start the engine. Hold the engine at 3,000 rpm with no load (in Park or Neutral) until the radiator fan comes on. 2. Raise the vehicle on a hoist. 3. Circulate the Dual Pump Fluid through the clutch assembly: • On A/T models: Apply the parking brake, put the transmission into D4, and let the vehicle idle for 5 minutes. • On M/T models: Put the transmission into 1st gear and engage the clutch. Slowly apply the parking brake until just before the engine stalls. Let the engine run like this for 5 minutes. 4. Engage both differential pumps: • On A/T models: Release the parking brake, and let the vehicle idle in D4 for 5 minutes. • On M/T models: Release the parking brake, and let the vehicle idle in 3rd or 4th gear for 5 minutes.
