whats the correct way way to change gears when ,climbing, up or down the box with a GMC hc451 fitted with a clark 5speed with direct top gear and an eaton two speed vac operated rear .
i,v driven allsorts of trucks , buses, and plant with allsorts of transmissions over the years and each has its own ,knack, as to how they like to be changed , and to be honest i dont think i,v ever drive a clark 5speed/eaton two speed combination .
cheers guys,,
