Removal Procedure
1. Remove the park/neutral back up switch. Refer to Park/Neutral Backup Switch Replacement.
2. Be sure that the jackscrew for the J 43911 is backed off and will not interfere with installation of the removal tool. Slide the seal remover tool over
the selector shaft (2) with the threaded end of the tool towards the seal.
3. Rotate the removal tool so that the threads on the end of the tool engage the steel shell (1) of the seal. Use a wrench to be sure that the removal tool
is firmly attached to the seal shell.
4. Rotate the jackscrew in the clockwise direction to remove the seal from the bore. Discard the seal that was removed.
Installation Procedure
1. Carefully slide a new selector shaft seal (1) over the selector shaft (2) with the wide face of the steel case facing outward. Position the seal so that
it is starting to enter the seal bore.
2. Obtain the J 43909 and remove the inner sleeve so that the tool will slide over the selector shaft.
