SERVICE INFORMATION
A two-piece design front engine mount is currently being used for the Applied Vehicles
listed.
A single thunk noise may be heard during the first few accelerations of the day from this
type of mount, and is considered normal operation.
The mount has also been designed with built-in free play that is normal.
Under normal driving conditions:

A thunk noise may be heard during the first few accelerations of the day.
And

Does not occur again, or at any other time.
DO NOT REPLACE THE MOUNT:

If it has free play or a “single event” thunk sound during the first few accelerations
of the day. This is considered a normal characteristic of this type of engine mount.

If a shift shock condition is present when shifting from park into gear or between any
combination of gears. This condition is due to transmissions line pressures and not
movement of the mount.
NOTE: Refer to the Electronic Service Manual, section TM – Transaxle &
Transmission, for further diagnostic information on shift shock.
