Overhaul (Differential)

A/T Differential

Backlash Inspection





1. Install both axles in the differential, and place the differential assembly on V-blocks (A).
2. Check the backlash of the pinion gears (B) with a dial indicator (C).
STANDARD: 0.05 - 0.15 mm (0.002 - 0.006 inch)
3. If the backlash is out of standard, replace the differential carrier.

Differential Carrier Replacement





1. Remove the snap ring (A) from the differential assembly (B).





2. Remove the speedometer drive gear (B).
3. Remove final driven gear bolts, then separate the final driven gear and the differential carrier. The final driven gear bolts have left-hand threads.





4. Install the final driven gear (A) on the new differential carrier (B) with the chamfered side on the inner bore facing the differential carrier.
5. Tighten the bolts to 103 Nm (10.5 kgf-cm, 75.9 ft. lbs.) in a crisscross pattern.





6. Install the speedometer drive gear (A) with its chamfered side facing the carrier.
7. Align the hooked end (B) of the snap ring (C) with the spring pin (D) in the pinion shaft (E), then install the snap ring in the differential carrier groove.

Final Driven Gear Replacement





1. Remove the final driven gear from the differential carrier. The final driven gear bolts have left-hand threads.
2. Install the final driven gear with the chamfered side on the inner bore (A) facing the differential carrier.
3. Tighten the bolts to 103 Nm (10.5 kgf-cm, 75.9 ft. lbs.) in a crisscross pattern.

Carrier Bearing Replacement

Special Tools Required
Driver 40 mm I.D. 07746-0030100





1. Remove the bearings (A) with a commercially available bearing puller (B) and stepper adapter (C).





2. Install the new bearings with the special tool and a press. Press the bearing on until it bottoms.

Oil Seal Replacement

Special Tools Required
^ Driver 07749-0010000
^ Driver Attachment 07NAD-PX40100
^ Driver attachment 07JAD-PH80101





1. Remove the oil seal (A) from the transmission housing (B).





2. Remove the oil seal (A) from the torque converter housing (B).





3. Install the oil seal (A) in the transmission housing with the special tools.





4. Install the oil seal (A) in the torque converter housing with the special tools.

Carrier Bearing Side Clearance Inspection

Special Tools Required
Driver 40 mm I.D. 07746-0030100





1. Install the 80 mm set ring (A) in the transmission housing (B).





2. Install the differential assembly (A) in the torque converter housing (B) using the special tool.
3. Align the spring pin (A) on the control shaft with the transmission housing groove (B) by turning the control shaft (C).

NOTE: Be careful not to squeeze the end of the control shaft tips together when turning the shaft. If the tips are squeezed together it will cause a faulty signal or position due to the play between the control shaft and the switch.





4. Install the three dowel pins (D) and the gasket (E) on the torque converter housing (F).
5. Place the transmission housing (G) on the torque converter housing.
6. Install the housing bolts along with the transmission hanger (H) and connector bracket (I). Tighten the bolts in two or more steps to 44 Nm (4.5 kgf-cm, 33 ft. lbs.) in a crisscross pattern.





7. Measure the clearance between the 80 mm set ring and carrier bearing outer race with a feeler gauge.
8. If the clearance is out of standard, remove the 80 mm set ring, and measure its thickness.
9. Select and install a new set ring, then recheck the clearance and make sure it is within the standard.
