A gearshift assembly comprises a base and a shift lever having an overmoulded ball portion comprising a pattern of recesses having straight side walls. A socket is fixed in the base and shaped to receive the ball portion of the shift lever. The socket has a sidewall with an inner surface forming part of a sphere to provide a pivotal mounting for the ball portion for pivotal movement of the shift lever over a pivotal movement range. Vertical slots in the sidewall which have parallel vertical side edges that are open at their upper ends to allow a sidewall portion between adjacent vertical slots to elastically flex outwardly during insertion of the ball portion into the socket. The pattern of recesses of the ball portion is arranged such that all sidewalls are inclined with respect to side edges of the vertical slots over the pivotal movement range.
