In the World Transmission design, what module contains all of the transmission's internal components?

• A. Main housing
• B. Main shaft
• C. Planetary
• D. Rear cover

Answer: (A)

The main housing is the enclosure that holds every internal part of the transmission. In World Transmission design, all gears, shafts, bearings, and related components are mounted inside this housing, which also provides the oil passages, seals, and mounting points that keep the entire gear train aligned and lubricated. The other options are individual parts or subassemblies: the main shaft is a rotating component inside the housing, the planetary is a specific gearset inside, and the rear cover simply seals the back of the case. So the main housing is the module that contains all internal components.
