When the overdrive on the M46 no longer engages, slips out or leaks oil, it's often not the whole unit that's worn out – but the seals, ball valve and worn bearings that have lost pressure. This category gathers wear parts and sealing details for the overdrive on the Volvo 240, so it engages smoothly and holds the gear on the highway.

The group includes O-rings and gaskets that seal against oil leaks, balls and plugs for the hydraulic circuit, plus washers, screws, lock rings and bearings for the mechanism itself. Common checkpoints during a rebuild are the ball valve and the O-rings around the piston – a worn seal lowers the oil pressure and makes the overdrive engage too late or not at all.
The parts fit the M46 gearbox overdrive in the Volvo 240. Always check against your existing unit, as the design differs between early and later model years.
