Caterpillar 777G Transmission

Description

OEM-Quality Caterpillar 777G Transmission Assembly

Restore smooth shifting, optimal power delivery, and maximum rimpull across your quarry and mining operations with a heavy-duty Caterpillar 777G Transmission Assembly. Engineered specifically for Caterpillar’s 100-ton class (91.4-tonne nominal payload) off-highway haul trucks, this electronically controlled planetary power shift transmission seamlessly manages high engine torque output from the Cat C32 ACERT engine down to the final drive axles.

Integrated with Caterpillar’s APECS (Advanced Productivity Electronic Control Strategy) technology, this transmission maintains momentum and speed through gear changes on steep grade climbs, reducing clutch wear and lowering overall cycle times.

Key Features & Benefits

• 7-Speed Planetary Power Shift: Heavy-duty planetary gear sets deliver 7 forward gear ratios and 1 reverse gear ratio, optimized for varying haul road speeds and steep incline loads.

• APECS Electronic Integration: Maintains hydraulic pressure during shifts to avoid power drops, providing smoother gear transition, better operator comfort, and longer component life.

• Heavy-Duty Clutch Packs: High-friction, heat-resistant clutch disc materials engineered to withstand repeated high-torque engagement under full load.

• Transmission Chassis Control (TCC) Compatible: Communicates continuously with the engine control module (ECM) to provide controlled throttle shifting and directional shift management.

• High-Flow Fluid Filtration & Cooling: Integrated oil channels allow for rapid transmission fluid recirculation, keeping thermal breakdown at bay during long, high-speed haul cycles.

• Direct OEM Mounting: Manufactured to precise Caterpillar 777G chassis tolerances for direct drop-in replacement onto engine torque converter outputs and frame crossmembers.
