4. Propeller Shaft Transmission Side - Disconnection





1. Make reference mark (A) across the No. 1 propeller shaft (B) and the transfer companion flange (C).

2. Separate the No. 1 propeller shaft from the transfer companion flange.

NOTE: Suspend the propeller shaft with an appropriate size nylon strap.

Inspection

1. Transfer Gear Backlash - Measurement





1. Shift the shift lever to N.

2. Set a dial indicator (A) on the companion flange (B).

3. Measure the transfer gear backlash.







4. If the backlash is out of the standard, replace the transfer assembly.

2. Transfer Fluid Leak - Check

1. Check for fluid leaks between the mating faces of the transfer assembly and the transmission.

2. If there is leak, remove the transfer assembly, then replace the O-ring.

3. Check for fluid leaks between the mating surfaces of the transfer housing and transfer shaft assembly.

4. If there is leak, remove the transfer shaft assembly, then replace the transfer shaft assembly O-ring.

5. Check for fluid leaks between the transfer companion flange and the transfer oil seal.

6. If there is leak, remove the transfer assembly, then replace the transfer oil seal and the O-ring on the transfer output shaft (hypoid gear).

NOTE: Do not replace the oil seal with the transfer assembly on the transmission.

Removal

1. ATF - Replacement





1. Remove the drain plug (A), and drain the ATF.

2. Reinstall the drain plug using a new sealing washer (B).

2. Under-Floor TWC Assembly





1. Remove the under-floor TWC.

3. Transfer Assembly





1. Remove the transfer assembly (A) and the dowel pin (B).

2. Remove the O-ring (C) from the transfer assembly.

Inspection

1. Total Starting Torque - Measurement





1. Secure the transfer housing (A) in a bench vise (B) with soft jaws.

NOTE: To prevent damaging the transfer housing, always use wood blocks or equivalent materials between the transfer housing and the bench vise.

2. Rotate the transfer companion flange several times to seat the tapered roller bearings.

3. Measure the starting torque at the companion flange (C) using a torque wrench (D) and a socket (E).







4. If the starting torque is out of the standard, replace the transfer assembly.

2. Transfer Drive Gear Tooth Contact - Inspection





1. Remove the transfer shaft assembly (A) and the dowel pin (B).





2. Remove the O-ring (A).

3. Apply Prussian Blue to both sides of the transfer drive gear (hypoid gear) (B) teeth lightly and evenly.





4. Temporarily install the transfer shaft assembly (A) and the dowel pin (B). Do not install the O-ring during inspection.

5. Rotate the companion flange in both directions until the transfer gears rotate one full turn in both directions.

6. Remove the transfer shaft assembly and the dowel pin.





7. Check the transfer drive gear (hypoid gear) tooth contact pattern. The pattern should be centered on the gear teeth as shown.

8. If the tooth contact pattern are incorrect, replace the transfer assembly.

Installation

NOTE: Apply a light coat of clean ATF on all moving parts before reassembly.

1. Transfer Shaft Assembly





1. Install a new O-ring (A).





2. Install the transfer shaft assembly (A) and the dowel pin (B).

2. Transfer Assembly





1. Install a new O-ring (A) on the transfer assembly (B).

2. Install the transfer assembly and the dowel pin (C).

3. Propeller Shaft Transmission Side - Reconnection





1. Set the No. 1 propeller shaft (A) to the transfer companion flange (B) by aligning the reference mark (C) you made during the removal procedure. Then install new flange bolts (D) to the specified torque.

4. Under Floor TWC Assembly





1. Install the under-floor TWC.

5. Front Floor Undercover





1. Install the front floor undercover (A), then install the bolts (B) and the clips (C, D). Make sure the clips snap into place securely.

6. Front Splash Shield





1. Install the front splash shield (A), then install the bolts (B) and the clips (C, D). Make sure the clips snap into place securely.

7. ATF - Replacement





1. Remove the ATF dipstick (yellow loop) (A), and wipe it with a clean cloth.





2. Refill the transmission with the recommended fluid into the dipstick guide tube opening (A) to bring the fluid level between the upper mark and the lower mark of the dipstick. Always use ATF DW-1 (genuine Honda automatic transmission fluid). Using a non-Honda ATF can affect shift quality.












3. Insert the dipstick (A) into the guide tube aligning the notch (B) with the guide tab (C).





4. Remove the dipstick.

5. Make sure the fluid level is between the upper mark (A) and the lower mark (B) on the dipstick.

6. Insert the dipstick into the guide tube aligning the notch with the guide tab.

8. Warm Up The Engine

1. Start the engine. Hold the engine speed at 3,000 rpm without load in P or N until the radiator fan comes on.

2. Park the vehicle on level ground.

3. Turn the ignition switch to LOCK (0).

9. ATF Level Check





NOTE:
* Keep all foreign particles out of the transmission.
* Check the fluid level within 60-90 seconds after turning the engine off.
* Higher fluid level may be indicated if the radiator fan comes on twice or more.

1. Remove the ATF dipstick (yellow loop) (A), and wipe it with a clean cloth.

2. Insert the dipstick into the guide tube aligning the notch (B) with the guide tab (C).





3. Remove the dipstick, and check the ATF level. It should be between the upper mark (A) and the lower mark (B).

4. If the ATF level is below the lower mark, check for fluid leaks at the transmission, the hoses, and the line joints. If a problem is found, fix it before filling the transmission with ATF.

NOTE: If the vehicle is driven when the ATF level is below the lower mark, one or more of these symptoms may occur:
* Transmission damage.
* Vehicle does not move in any gear.
* Vehicle accelerates poorly, and engine revs up abnormally high when starting off in forward and reverse positions.
* Engine vibrates at idle.

5. If the ATF level is above the upper mark, drain the ATF to proper level.

NOTE: If the vehicle is driven when the ATF level is above the upper mark, the vehicle may creep forward while in N, or have shifting problems.





6. If necessary, fill the transmission with ATF through the dipstick guide tube opening (A) to bring the fluid level between the upper mark and the lower mark of the dipstick. Do not fill the fluid above the upper mark. Always use ATF DW-1 (genuine Honda automatic transmission fluid). Using a non-Honda ATF can affect shift quality.

7. Insert the dipstick into the guide tube aligning the notch with the guide tab.

10. HDS DLC - Connection





1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.

2. Turn the ignition switch to ON (II).

3. Make sure the HDS communicates with the vehicle. If it does not communicate, go to the DLC circuit troubleshooting.
