Inspection

1. Check synchronizer rings for wear or damage. It is recommended that new synchronizer rings be installed when transmission is being disassembled.

2. Check synchronizer rings as follows:

a. Place synchronizer ring over respective gear tapered mating surface. Included intermediate and internal rings for 1st and 2nd gear.

b. While holding ring centered, measure gap between gear and synchronizer teeth and synchronizer ring teeth using a feeler gauge.

c. Replace synchronizer ring if measurement is less than 0.050 inch for 1-2, 3-4, and 5-6 gear. Replace synchronizer ring for reverse gear if measurement is less than 0.028 inch.
