3. Attach the wrench (40 x 42 mm) onto the 1st clutch guide, and secure the wrench (40 x 42 mm) with the vise to hold the secondary shaft. Loosen the locknut, and remove it. Remove any burrs from splines on the shaft and splined washer.
4. Place the idler gear (A) on press bases (B), and place a spacer (C) between the secondary shaft (D) and a 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, the 1st gear assembly, the needle bearing, the 1st gear collar, the 43.5 x 59 x 2.5 mm thrust needle bearing, and the idler gear.
7. Remove 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 on the 1st gear collar contains the only two no-roller cavities; 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 (see SECONDARY SHAFT 1ST GEAR AXIAL CLEARANCE INSPECTION  ), 1st gear one-way clutch (see 1ST GEAR ONE-WAY CLUTCH INSPECTION  ), and secondary shaft installation height (see SECONDARY SHAFT INSTALLATION HEIGHT INSPECTION/ADJUSTMENT  ).
