摘要： A countershaft type power transmission has a plurality of selectively engageable friction clutches for establishing a plurality of forward drive ratios and a reverse drive ratio between meshing gear members on an input shaft (12), a countershaft and an output shaft (50). One of the power paths established by the meshing gears includes a gear member (48) rotationally fast on the output shaft. A parking pawl member (74) is selectively engageable with this gear member to prevent output shaft rotation when parking is desired. The pawl has teeth (80A-D) formed thereon having a profile which permit continuous simultaneous engagement between two teeth on the pawl and two teeth (78) on the gear member regardless of the rotational bias imposed on the output shaft during parking.
