Park Mechanism
Park MechanismThe park mechanism locks the transmission by engaging the park pawl with the park gear which is splined to the countershaft.
Shifting to P position causes the park cone (installed at the end of the park rod) to press the park pawl onto the park gear. Even if the end of the park pawl rides on top of the park gear teeth, slight movement of the countershaft will cause the park pawl and the park gear to mesh with each other completely because the park cone receives tension from the park rod spring. The park pawl receives the tension (which acts to separate the park pawl from the park gear) from the park pawl spring.
