Power Transfer Unit (PTU)

Power Transfer Unit (PTU)

Torque from the engine goes through the transaxle to the power transfer unit (PTU). Torque is transferred from the driveshaft to the rear axle, which drives the rear halfshafts.

The vehicle is equipped with an intelligent all wheel drive (AWD) system that is always active and requires no driver input. The AWD system combines transparent all-surface operation, and is capable of handling all road conditions, including street and highway driving as well as winter driving. The AWD system continuously monitors vehicle conditions and automatically adjusts the torque distribution between the front and rear wheels. During normal operation, most of the torque is sent to the front wheels. If wheel slip between the front and rear wheels is detected, or if the vehicle is under heavy acceleration (HIGH THROTTLE position), the AWD system increases torque to the rear wheels to prevent or control wheel slip.








Serviceable components of the PTU include 3 seals, the input shaft oil slinger, the halfshaft dust seal, the vent cap fitting, the vent cap and filter and the output flange. If any of the internal geared components, bearings or shafts are worn or damaged, a new PTU must be installed. The PTU is sealed from the transaxle and has its own oil sump.
