4. Remove third gear from shaft, then remove snap ring retaining second gear on shaft and remove tabbed second gear thrust washer and second gear.

5. Using tool J-29721 and adapters 293-39 or equivalent, remove output shaft rear bearing.

6. Remove first gear thrust washer, first gear roll pin, first gear, and blocking ring.

7. Mark alignment of first-second gear synchronizer sleeve and output shaft hub for assembly reference, then remove insert spring and inserts from first-reverse sliding gear and remove gear from output shaft hub.
