Remove the 32 mm snap ring, and remove the 2nd clutch, the splined washer, the thrust needle bearing, the needle bearing, the 2nd gear/park gear, and the thrust needle bearing.
Inspect the bearing for galling and rough movement.
Check the shaft bearing surfaces for scoring and excessive wear, and check the shift splines for excessive wear and damage.
Check the 1st gear axial clearance (see SECONDARY SHAFT 1ST GEAR AXIAL CLEARANCE INSPECTION ), the 1st gear one-way clutch (see 1ST GEAR ONE-WAY CLUTCH INSPECTION ), and the secondary shaft installation height (see SECONDARY SHAFT INSTALLATION HEIGHT INSPECTION/ADJUSTMENT ).
