Perfect All Around Gearboxes

This mod provides three universal gearbox configurations designed for smooth cruising at low RPM at 45, 55, and 65 mph. Each gearbox is optimized for engines with peak torque at 900, 1000, or 1200 RPM, featuring 18 forward gears, 4 reverse gears, crawler gears, and a 3-step retarder. They are built to handle heavy loads uphill with ease while maintaining efficient highway speeds at low RPM. Please note that a powerful engine is recommended for the higher gears. Compatible with all vanilla trucks as well as popular mod trucks including the Kenworth W990, Freightliner FLB, Mack R, and Overfloater K100e.
