Exploded View





Special Tools Required

- Wrench, 40 x 42 mm 07XAA-002010A

NOTE: Refer to the Exploded View as needed during the following procedure.

1. Cut the lock tab (A) off the secondary shaft locknut (B) using a chisel (C).

NOTE: Keep all of the chiseled particles out of the secondary shaft.






2. Place a V-block (A) on a bench vise (B), and put the secondary shaft (C) on the V-block and the bench vise.





3. Attach the 40 x 42 mm wrench onto the 1st clutch guide, and secure the 40 x 42 mm wrench with the bench vise to hold the secondary shaft. Loosen the locknut, and remove it. Remove any burrs from splines on the shaft and the splined washer.

4. Place the idler gear (A) on press bases (B), and place a spacer (C) between the secondary shaft (D) and the press to prevent damaging the secondary shaft.





5. Support the bottom of the secondary shaft with one hand, then press the secondary shaft out of the press-fitted bearing (E). The secondary shaft will drop down after pressing it out of the press-fitted bearing.

6. Remove the 1st/1st-hold clutch, the 52 mm washer, the 40 x 57 x 2.5 mm thrust needle bearing, 1st gear assembly, the needle bearings, the 1st gear collar, the 43.5 x 59 x 2.5 mm thrust needle bearing, and the idler gear.

7. Remove the 29 mm sealing rings and the 32 mm snap ring, and remove the 2nd clutch, the splined washer, the needle bearings, the 2nd gear/park gear, and the 44 x 66 x 3.5 mm thrust needle bearings.

8. Inspect the bearings for galling and rough movement.

NOTE: The needle bearing (A) on the 1st gear collar contains the only two no-roller cavities (B); this is normal.





9. Check the shaft bearing surfaces for scoring and excessive wear, and check the shaft splines for excessive wear and damage.

10. Check the 1st gear axial clearance A/T Secondary Shaft 1st Gear Axial Clearance Inspection, the 1st gear one-way clutch A/T Secondary Shaft 1st Gear One-Way Clutch Inspection, and the secondary shaft installation height A/T Secondary Shaft Installation Height Inspection/Adjustment.
