Good original 1995 Chevrolet and GMC Dealer Service Manual Set. These Manuals cover the PG and P3 Chassis Truck Models. These were used by the Dealership to Service and repair your Truck. The Allison Automatic Transmission Supplement is included. They include information, specifications, procedures, illustrations, diagrams and trouble shooting for your vehicle. Very informative and useful tool that is hard to find since they were not available to the public.
