Park the vehicle on a level surface.

Use the table below to help you find the cause of the problem. The numbers indicate the ranked order of probability of each of the possible causes. Check each part in order. Replace parts as necessary.

Using SST and a press, install a new needle roller bearing inner race.

Using a dial indicator and 2 V-blocks, measure the shaft runout.

• Maximum runout:
• 0.03 mm (0.0012 in.)

If the runout exceeds the maximum, replace the counter gear.

Using a feeler gauge, measure the reverse gear thrust clearance.

• Standard clearance:
• 0.12 to 0.28 mm (0.0047 to 0.0110 in.)

If the clearance is outside the specification, replace the defective gear, spline piece or bearing race.

Using SST and a press, install a new output shaft front bearing onto the output shaft.

Using a cylinder gauge, measure the inside diameter of the output shaft.

• Standard inside diameter:
• 45.009 to 45.025 mm (1.7720 to 1.7726 in.)

• Maximum inside diameter:
• 45.025 mm (1.7726 in.)

If the diameter exceeds the maximum, replace the output shaft.

Remove the No. 3 synchronizer ring from the output shaft.
