Place the secondary shaft on the block, and attach the 1st clutch guide (D) to the wrench (40 x 42 mm). Loosen the locknut, and remove it. Remove any burrs from the splines on the shaft and the splined washer.
Place the idler gear (A) on press bases (B), and place a shaft protector (C) between the secondary shaft (D) and a press to prevent damaging the secondary shaft.

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.
Remove the 1st/1st-hold clutch, the 52 mm washer, the thrust needle bearing, the 1st gear assembly, the needle bearing, the 1st gear collar, the thrust needle bearing, and the idler gear.
Remove the 32 mm snap ring, and remove the 2nd clutch, the splined washer, the thrust needle bearing, the needle bearings, the 2nd gear/park gear, and the thrust needle bearing.
Inspect the bearings for galling and rough movement.
NOTE: The needle bearing (A) on the 1st gear collar should have only two cavities with no rollers (B); this is function in its normal.
