the selector lever will be burred. Use a fine
file to remove any burrs and then proceed.
12 Fit the second plastic seal installer over the manual shaft until it seats against the first installer.
13 Install the manual shaft linkage attaching nut (5) and tighten it to drive the seal in position into the
transmission case.
14 Remove the seal installer and protector tools from the manual shaft.
Figure 7C4 – 18
15 Reinstall the neutral start and back-up lamp switch, refer to 3.4 Neutral Start and Back-up Lamp Switch.
