Abstract
A transmission shifter (12) for controlling a transmission includes a pair of independent spring biasers (30,32) mounted by a housing (18) to bias an operating member (22) of the shifter and respectively control lateral movement of the operating member in opposite lateral directions independently of each other. Each spring biaser (30,32) preferably includes at least one helical spring (34,36 and 38) for providing the biasing with the lateral bias of one spring biaser greater than that of the other. One of the helical spring biasers (30) includes a pair of helical springs (34,36) one of which has a larger diameter and receives the other, and the other spring biaser (32) includes a single helical spring (38) identical to the larger spring (34) of the one biaser (30). The shifter (12) also includes a ball and pin construction (42,44) for mounting the operating member (22) and a seat and shim arrangement (56,60 and 58,62) for mounting the spring biasers.
