Owner Letter
March, 1993
Dear 1988-93 Chevrolet C/K Truck Owner:
This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.
REASON FOR THIS RECALL
General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1988-93 C/K model trucks equipped with certain
combinations of 5.0L, 5.7L & 7.4L engines and 4L60, 4L60-E & 3L8O automatic transmissions.
The transmission fluid in these vehicles, as a result of unanticipated heat generation in the transmission, may be forced out of the vent tube. The heat
generation is usually the result of trailering heavy loads at high speeds or high-load/off-road use. If the vented transmission fluid comes in contact with
the catalytic converter, ignition of the transmission fluid may result.
WHAT WE WILL Do
While the occurrence of this ignition has been infrequent, Chevrolet wants to eliminate the possibility of it happening. Therefore, dealers have been
instructed to install a longer transmission vent hose routed to the left side of the vehicle. This service will be performed for you at no charge.
WHAT YOU SHOULD DO
Please contact your Chevrolet dealer as soon as possible to arrange a service date and so the dealer may order the necessary parts for the repair.
Instructions for making this correction have been sent to your dealer and parts are available. The labor time necessary to perform this service correction
is approximately ten (10) minutes. Please ask your dealer if you wish to know how much additional time will be needed to schedule and process your
vehicle.
Also, enclosed with this letter is updated information on towing or off-road use with an overdrive equipped automatic transmission. Please review this
information and keep it with your owner's manual.
Your Chevrolet dealer is best equipped to obtain parts and provide service to ensure that your vehicle is corrected as promptly as possible. If, however,
you take your vehicle to your dealer on the agreed service date, and they do not remedy this condition on that date or within five (5) days, we recommend
you contact the Chevrolet Customer Assistance Center by calling 1-800-222-1020.
After contacting your dealer and the Customer Assistance Center, if you are still not satisfied that we have done our best to remedy this condition without
charge and within a reasonable time, you may wish to write the Administrator, National Highway Traffic Safety Administration, 400 Seventh Street,
S.W., Washington, D.C. 20590 or call 1-800-424-9393 (Washington D.C. residents use 366-0123).
The enclosed owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary correction in the
shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage paid reply card and returning it to us.
We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your safety and continued satisfaction with our
products.
