5. Reinstall the drain plug with a new sealing washer (B).  

6. Refill the transmission with the recommended fluid through the filler hole (A). Always use Acura ATF-

Z1 Automatic Transmission Fluid (ATF). Using a non-Acura ATF can affect shift quality. 

Automatic Transmission Fluid Capacity:  

2.7 L (2.9 US qt) at change  

7.2 L (7.6 US qt) at overhaul

6. Refill the transfer assembly with the recommended fluid (hypoid gear oil) through the filler hole (C) until 

the fluid flows out. Use a SAE 90 or SAE 80W-90 viscosity hypoid gear oil, API classified GL4 or GL5 
only. 

Viscosity:  

SAE 90: Above 0°F (-18°C)  

SAE 80W-90: Below 0°F (-18°C)  

Transfer Fluid (Hypoid Gear Oil) Capacity:  

0.43 L (0.45 US qt) at fluid change  

7. Install the filler plug with a new sealing washer.  

TRANSFER ASSEMBLY INSPECTION 

1. Raise the vehicle on a lift, and make sure it is supported securely.  

2. Shift the transmission into N.  

3. Make a reference mark (A) across the propeller shaft (B) and the transfer companion flange (C).

4. Separate the propeller shaft from the transfer companion flange.  

5. Set a dial indicator (A) on the transfer companion flange (B); position the dial indicator tip (C) on the top 

of the bolt (D).

6. Measure the transfer gear backlash. 

Standard: 0.06-0.16 mm (0.002-0.006 in.)  

7. If the backlash is out of standard, remove the transfer assembly, and adjust the transfer gear backlash (see 

REASSEMBLY ).  

8. Check for fluid leaks between the mating surfaces of the transfer assembly and the transmission.  

9. If there is a leak, remove the transfer assembly, remove the transfer cover, and replace the O-ring.  

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

11. If there is a leak, remove the transfer assembly from the transmission, and replace the transfer oil seal and 

O-ring on the transfer output shaft (hypoid gear). If an oil seal and O-ring replacement is required, you 
will need to check and adjust the transfer gear tooth contact, the transfer gear backlash, the tapered roller 
bearing starting torque, and the total starting torque (see REASSEMBLY ). Do not replace the oil seal 
with the transfer assembly on the transmission.  

TRANSFER ASSEMBLY REMOVAL 

1. Raise the vehicle on a lift, and make sure it is supported securely.  

2. Shift the transmission into N.  

3. Remove the ATF filler bolt and drain plug (A), and drain the automatic transmission fluid (ATF).
