If the manual shift lever is rotated prior to installing the Park-Neutral position switch, the detent spring may become detached from the manual shift lever. When performing automatic transmission and/or Park-Neutral position switch service on the models listed, make sure that the manual shift lever is NOT rotated prior to installing the Park-Neutral position switch.
If the detent spring becomes detached from the manual shift lever, remove the detent spring and reinstall on the manual shift lever.
Do not attempt to force the manual shift lever into position with the detent spring installed, as this may damage the spring. The detent spring must be removed when repositioning the manual shift lever.
