Disassembly And Assembly: Disassembly

WARNING: This page is about a different car, the 2004 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

Before disassembling, measure the end play for 3rd, 4th, 5th, and 6th input gears.
End play standard values

3rd gear : 0.18 - 0.31 mm (0.0071 - 0.0122 in)

4th gear : 0.20 - 0.30 mm (0.0079 - 0.0118 in)

5th gear : 0.06 - 0.16 mm (0.0024 - 0.0063 in)

6th gear : 0.06 - 0.16 mm (0.0024 - 0.0063 in)

CAUTION: If measurement is outside the standard value, disassemble to check the contact surfaces of the gear, shaft, and hub. Adjust using the correct size snap ring for assembly.
