Vibrations in the floor at idle and a dull thud when you shift into first or reverse can point to a tired or cracked gearbox pad. The rubber hardens and cracks over the years, which is a common check point when the M40 gearbox in a 240 starts to feel rattly.
This category gathers parts for mounting and securing the manual M40 gearbox. The group includes gearbox pads and mounts along with the screws, flange screws, washers, lock washers, copper washers and o-rings that belong to the attachment to the member. Keep in mind that thread and dimension (e.g. UNC) vary – check the measurements against your car before installation.
