System Notes — POWER TRAIN
The power train group covers the components between the engine and the ground: torque converter, transmission, driveshaft, differential, final drives and the clutches and seals inside them. It multiplies engine torque into the pulling force the machine needs. Heat and contamination cause most failures — oil that has broken down varnishes the clutch packs, a leaking final drive seal lets grit into the planetary set, and a worn driveshaft joint shows up first as a vibration at a particular speed. Parts are replaced when shift quality degrades, when a vibration appears at one speed band, or when oil analysis shows the wrong metal.
