This mod brings back old twin stick 5×4 (20 gears) and 6×4 (24 gears) transmissions for ReneNate’s Mack b61 truck mod. As some gears are repetitive and/or useless, these gearboxes are difficult to drive. I included a .txt file with instructions and all the gear ratios, aswell as some usefull links for h-shifter players! ATS Version: 1.47.x (This mod might work in other Mack b61 trucks)
