chipping or distortion.
- Replace the shift shaft if faulty.
- Inspect the 1st/2nd shift fork for scoring, distortion,
or wear through the hardened surface.
- Inspect for a bent shift fork.
- Inspect for cracks in the shift fork.
- Inspect the shift rail holes for excessive wear.
- Replace the shift fork if faulty.
- Using a feeler gage, measure the clearance between
the reverse gear and the shift fork.
Specification

or wear through the hardened surface.
- Inspect for a bent shift fork.
- Inspect for cracks in the shift fork.
- Inspect the shift rail hole for excessive wear.
- Replace the shift fork if faulty.
- Using a feeler gage, measure the clearance between
the 3rd/4th synchronizer sleeve and the shift fork.
Specification
Maximum Clearance: 1.0 mm (0.039 in)
- If the clearance exceeds the maximum, replace the shift fork or the
sleeve.
- Inspect the reverse shift fork and the reverse shift
lever for wear or damage.
- Replace the reverse shift fork or the reverse shift lever if found
faulty.
- Using a feeler gage, measure the clearance between
the reverse idler gear and the reverse shift fork.
Specification
