Speed Governor

Every U-Haul truck I’ve rented had a,governors. My first wife’s father drove for a feed company. He owned his own trucks. He had his own trucks fitted with a governor. He would always,start in second and accelerate until he felt the governor limir the engine rpm then shift to the next gear. I used his technique when I rented the U-Hauls with manual transmissions. In my opinion, it isn’t good for an engine to lug it in a gear that is too high for the conditions. With a governor to limit the rpms, running the engine up to the governor limit doesn’t hurt the engine, particularly when the truck is loaded. It’s certainly better than lugging the engine. Automatic transmissions calibrated to shift at the correct point.
