AFFECTED VEHICLES
Vehicles involved in this program are certain 1987-1993 passenger cars equipped with automatic overdrive transmissions that were originally sold or are
currently registered in counties of the extreme southern states which experience both high humidity and high temperatures. This area is generally in a
band extending approximately 100 miles north from the Gulf of Mexico coastline in the following states plus the entire state of Hawaii and Florida:
Alabama, Georgia, Louisiana, Mississippi and Texas. Affected vehicles can be identified by checking OASIS. Specific vehicle information - See
illustration.
REASONS FOR THIS PROGRAM
The urethane grommet that holds the transmission throttle valve cable in the throttle body lever may deteriorate and fall out allowing the cable to
disconnect from the lever. Should the cable become disconnected during normal vehicle operation, the transmission bands and clutches will immediately
begin to slip. Under this condition, the bands and clutches will wear out within several miles, rendering the vehicle inoperative.
SERVICE ACTION
To correct this condition, dealers are to replace the urethane throttle lever grommet with a brass bushing and steel retaining clip.
In instances where an owner whose vehicle is not listed in OASIS believes the vehicle should have been included or this condition is observed in a
vehicle not covered by this action, obtain prior FCSD District Office approval and submit an 1863 claim via DWE in the normal manner for
reimbursement.
REFUNDS
Only for owner-paid repairs made before date of Owner Letter.
