Dear GMC Truck Owner:
General Motors has determined that transmission fluid may leak from the transfer case adapter where it meets the transfer case on some 1986 K35
models equipped with a 4 speed manual transmission. This condition may be caused by an improperly machined transfer case adapter.
To correct this condition if it exists in your vehicle, the adapter will be inspected and replaced if necessary. This service will be performed for you at no
charge.
Instructions for this service have been sent to your GMC Truck dealer. Please contact your dealer to arrange a service date. The labor time to inspect
your vehicle in approximately 1-1/2 hours. If the transfer case adapter must be replaced it will take an additional 30 minutes. Please ask your dealer if
you wish to know how much additional time will be needed to process your vehicle.
The enclosed owner reply card identifies your vehicle. Presentation of this card to your dealer will assist them in making the correction to your vehicle in
the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage paid owner 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 continued satisfaction with our products.
