<p>The mechanism comprises a locking member (42) mounted for translational movement in a direction transverse to the gear select direction and an abutment surface (66) which limits the translational movement of the locking member (42). During selection of reverse ratio by a selector (26, 126) the locking member (42) is brought into contact with part (58) of a forward ratio selector (20) so as to cause the locking member (42) to undergo said translational movement until it contacts the abutment surface (66). Continued movement of the reverse ratio selector (26, 126) causes the locking member (42) to shift the forward ratio selector (20) so as to operate a synchroniser (28) of the forward ratio synchromesh prior to the engagement of reverse ratio and thereby prevent gear clashing when selecting reverse.</p> |
