CAMPAIGN: REVERSE SIGNAL PRESSURE SWITCH LEAKS
SUBJECT: REVERSE SIGNAL PRESSURE SWITCH LEAKS
MODELS: 1995 B7 SCHOOL BUS CHASSIS, P6 CHASSIS, C6/7 TOPKICK/KODIAK MEDIUM DUTY CONVENTIONAL TRUCKS EQUIPPED WITH ALLISON AT/MT SERIES AUTOMATIC TRANSMISSIONS (RPO'S MF1, MT9, ME3, ME4, ME5, AND ME6)
The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle which is subject to a recall campaign of this type must be adequately repaired within a reasonable time after the owner has tendered it for repair. A failure to adequately repair within 60 days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time.
If the condition is not adequately repaired within a reasonable time, the owner may be entitled to an identical or reasonably equivalent vehicle at no charge, or to a refund of the purchase price less a reasonable allowance for depreciation.
To avoid having to provide these burdensome solutions, every effort must be made to promptly schedule appointments with owners and to repair their vehicles as soon as possible. As you will see in reading the attached copy of the letter which is being sent to owners, the owner is being instructed to contact GMC Truck Consumer Relations if the dealer does not remedy the condition within five days of the mutually agreed upon service date. If the condition is not remedied within a reasonable time, they are instructed how to contact the National Highway Traffic Safety Administration.
DEFECT INVOLVED
General Motors has decided that CERTAIN 1995 B7, P6, C6-7 model trucks fail to conform to Federal Motor Vehicle Safety Standard (FMVSS) 108, "Lamps, Reflective Devices, and Associated Equipment". These vehicles were assembled with a transmission reverse signal switch that could leak resulting in loss of electrical contact when the transmission is in reverse. This condition could prevent the backup warning system (lights and audible alarm) from operating properly.
To correct this condition, dealers will replace the reverse signal pressure switch with one date coded 145 (14th week of 1995) or later.
VEHICLES INVOLVED
Involved are CERTAIN 1995 B7 School Bus chassis, P6 Chassis, and C6/7 TopKick/Kodiak medium duty conventional trucks equipped with Allison AT/MT series automatic transmissions built within the following VIN breakpoints:
Model Year Model From Through
1995 B7 SJ105350 SJ520182 1995 P6 SJ106409 SJ519239 1995 C6/7 SJ105366 SJ520157
The specific vehicles involved in this campaign have been identified by Vehicle Identification Number Computer Listings. These listings are furnished to all involved dealers with the campaign bulletin. Dealers should confirm vehicle eligibility through VISS (Vehicle Information Service System) or SERVICENET prior to beginning campaign repairs.
DEALER CAMPAIGN RESPONSIBILITY
All unsold vehicles in dealers' possession and subject to this campaign MUST be held and inspected/repaired per the service procedure of this campaign bulletin BEFORE owners take possession of these vehicles.
Dealers are to service all vehicles subject to this campaign at no charge to owners, regardless of mileage, age of vehicle, or ownership, from this time forward.
Owners of vehicles recently sold from your new vehicle inventory with no owner information indicated on the dealer listing, are to be contacted by the dealer, and arrangements made to make the required correction according to the instructions contained in this bulletin. This could be done by mailing to such owners a copy of the owner letter accompanying this bulletin. Campaign follow-up cards should not be used for this purpose, since the owner may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this campaign enters your vehicle inventory, or is in your dealership for service in the future, please take the steps necessary to be sure the campaign correction has been made before selling or releasing the vehicle.
This bulletin is notice to you that the new motor vehicles involved in this campaign may not comply with the standard identified above. Under Section 108 of the National Traffic and Motor Vehicle Safety Act, it is illegal for a dealer to sell a new motor vehicle which the dealer knows does not comply with an applicable Federal Motor Vehicle Safety Standard. As a consequence, if you sell any of these motor vehicles without first performing the campaign correction, your dealership may be subject to a civil penalty up to $1,000 for each such sale.
If the name and address of the owner of an involved vehicle was unavailable to GMC Truck Division at the time of campaign initiation, the dealer must determine the owner's name and address from the dealership sales records. Please provide this information directly on the second copy of the listing next to the applicable VIN so that our records may be updated and the appropriate notification mailed to the owner. This second copy should then be submitted to the address listed below in the previously supplied yellow campaign envelopes.

Dear GMC Truck Customer:
This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.
General Motors has decided that CERTAIN 1995 B7, P6, C6-7 model trucks fail to conform to Federal Motor Vehicle Safety Standard (FMVSS) 108, "Lamps, Reflective Devices and Associated Equipment". These vehicles were assembled with a transmission reverse signal switch that could leak resulting in loss of electrical contact when the transmission is in reverse. This condition could prevent the backup warning system (lights and audible alarm) from operating properly.
To correct this condition your GMC Truck dealer will replace the reverse signal pressure switch. This service will be completed for you at no charge.
Instructions for making this correction have been sent to your GMC dealer. Please contact your GMC Truck dealer as soon as possible to arrange a service date. The labor time necessary to perform this correction will be approximately 25 minutes. Please ask your dealer how much additional time will be needed to process your vehicle.
Your GMC dealer is best equipped to provide service to ensure your vehicle is corrected as promptly as possible. However, if you take your vehicle to your dealer on the agreed service date and they do not service this condition on that date or within five days, we recommend you contact GMC Truck Consumer Relations by telephone. Consumer Relations will assist you and your dealer in getting your vehicle corrected. The telephone number of the Consumer Relations office is listed in your Warranty and Owner Assistance Information Manual.
After contacting your GMC Truck dealer and GMC Truck Consumer Relations, if you are still not satisfied that we have done our best to remedy this condition without charge 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 800-424-9393 (Washington, D.C. residents use 202-366-0123).
The enclosed postage paid owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary correction to your vehicle in the shortest possible time. If you have sold or traded your vehicle, please furnish the complete name and address of the person you sold or traded your vehicle to and return the card to GMC Truck.
We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued safety and satisfaction with our products.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
