An apparatus and methods are provided for a transmission for a rear mid-engine vehicle. The transmission comprises a power transfer portion for receiving torque from the engine and a gearbox for providing conversions of rotational speed and torque. First and second side output portions conduct torque from the gearbox to the rear wheels. A forward output portion conducts torque to front wheels of a four-wheel drive vehicle. An air clutch comprising each output portion controls the degree of torque transferred to each wheel. The output portions are each coupled to a rear wheel by a rear axle, bevel gears, and rear portal gears. The rear axles are aligned with, and positioned above, the trailing arms to protect the rear axles from damage due to rocks and debris. The length and alignment of the rear axles cause CV joints to articulate in the same direction as the trailing arms.
