Bulletin 68-C-1 — Pontiac Motor Division Dealer Product Campaign Bulletin, Section 7F, dated October 30, 1967. Attention: Service Manager.

Subject: 1968 Six-Cylinder Firebird Transmission Cooler Pipe Replacement.

Short answer: Some early 1968 six-cylinder Firebirds with automatic transmission (built through serial number 80601801) were fitted with transmission-to-radiator cooler pipes that may fatigue and leak; dealers must replace both pipes using new Part Nos. 9793994–5 before delivery and contact all affected owners.

Vehicles Involved

Automatic transmission, six-cylinder Firebirds built through the following serial number breakpoint:

80601801

All Firebirds built after the above serial number breakpoint will have proper cooler pipes installed. Included with this bulletin is a listing of the vehicles involved in this campaign that were shipped to your dealership. If you do not receive a listing, you can assume that you have no vehicles to do except for possible tourists and transferees.

Vehicles in stock are to be modified prior to delivery. Modify all vehicles in stock immediately so that none of your customers receiving these cars will be inconvenienced by possible loss of transmission fluid and resultant harsh shift characteristics.

Owner Notification

Pontiac Motor Division is sending a letter to those owners of record asking them to contact your dealership. Contact all of your owners by phone and urge them to bring their cars in as soon as possible. Please campaign the vehicle of any owner who brings his car into your dealership for this correction regardless of where he took delivery of his car.
