ISSUE
A "buzzing" noise may be heard at certain speeds and loads coming from the shift lever. This may be caused by the powertrain producing vibrations that
cause the shifter to vibrate since it is not isolated.
ACTION
Replace the shifter and shifter handball. The revised shifter and shifter handball isolate the assembly from the powertrain. Refer to the following Service
Procedure for details.
