Driving downhill in wrong gear

TM 9-2320-211-20-3-2

(7) Driving downhill in wrong gear. The speed field (Fig. 20-13) will record

truck speed that changes constantly because the weight of the truck will try to make

the truck go faster. When the service brakes are put on, heavy stress is put on the

brakes and the transmission components. The rpm field will also show constant

change between high and low rpm. With this kind of driving the engine can easily

run at very high rpms.
