Anyone have tips on how to down-shift this gear box? I recently bought a Ford 800 with cummins diesel and this transmission. No manual on trans. It is a 5 speed with the splitter switch to go to 10 speed. Goes up fine, but coming down is real bitch- she wants to grind. I think it only like a "little" clutch and very rpm sensative. any tips?
