J2-25prose procedureManual transaxle (M/T) secondary shaft preinspection.
Preinspection
1st gear thrust clearance
- 1Measure the clearance between 1st gear and the differential drive gear.

- 2If the clearance exceeds the maximum, check the contact surfaces of the 1st gear, differential drive gear of the secondary shaft gear, and 1st/2nd clutch hub assembly. Replace worn and damaged parts.

2nd gear thrust clearance
- 1Measure the clearance between 2nd gear and secondary 3rd gear.

- 2If the clearance exceeds the maximum, check the contact surfaces of the 2nd gear, secondary 3rd gear, and 1st/2nd clutch hub assembly. Replace worn and damaged parts.
