ABSTRACT:
An automatic transmission has a park system with a shaft and a parking pawl. The shaft rotates in response to a gear shift lever, and a detent lever positions the parking pawl in response to rotation of the shaft. A detent spring assembly biases the detent lever and has a detent spring, cage, and roller assembly. The cage aligns the roller assembly, while the detent spring is connected to the cage at one end and has a flat reaction surface formed at a second end. A cage notch portion aligns the cage with the detent lever, and the roller assembly into a perpendicular orientation with detent lever teeth. The notch portion engages either a detent tooth or a stationary portion of an internal mode switch (IMS). A shaft inserts into a roller through a side hole in the cage to retain the roller assembly therewithin.
