Abstract
A hydraulic park system includes a spool valve linked to a park mechanism. In some circumstances, a hold-out-of-park mechanism is utilized to hold the spool in position. To avoid wear on the aluminum spool, a steel saddle is inserted onto the spool between two lands such that the hold-out-of-park mechanism engages the steel saddle. The steel saddle is inserted from the side of the spool. To ensure that the hold-out-of-park engages the correct side of the saddle, the saddle must be held in a predefined circumferential position about the bore axis. The saddle is constrained from rotation about the spool axis by abutting flat surfaces on the spool and the saddle. The spool is constrained from rotation relative to the bore by the park mechanism.
