There are currently two sections with the title "Specifications (Power Train)" in this module. One section is effective for 769D (S/N: 5SS) Off-Highway Truck, 69D (S/N: 9XS) Off-Highway Truck, and 771D (S/N: 6YS) Quarry Truck. The other section is effective for 769D (S/N: BBB) Off-Highway Truck and 771D (S/N: BCA) Quarry Truck. These sections have been combined and revised. Replace both "Specifications (Power Train)" sections with the following information.
