Play in the shift action, a lever that wanders sideways or gears that catch in the wrong position are common wear points on the 122 with M40 column shift. The fault often lies in worn bushings and a chewed locking pin rather than in the gearbox itself, so the control linkage is worth checking before you suspect anything bigger.

This category gathers wear and repair parts for the lever mechanism and linkage on the column-mounted M40. The group includes bushings, o-rings, safety rings and locking pins plus screw, nut, washer and gears – parts that restore play and precision in shifting. When refurbishing, it is smart to replace bushings and safety rings together so the whole control gets even fit again.
The design differs between column shift and floor-mounted lever, so check which control your car has before ordering.
