Gearbox overdrive D-type Volvo 140 (B18)

When the overdrive engages slowly, drops out unexpectedly or won't engage at all, the culprit is often dirty oil, worn O-rings and sluggish valve balls. This category gathers wear and sealing parts for the D-type Laycock overdrive on the Volvo 140 and 164 with the B18 engine — in other words, the parts you replace during an overhaul rather than condemning the whole unit.

The group includes gaskets and O-rings to seal the hydraulic circuit, balls and washers for the valve work, studs and nuts for mounting to the box, plus bearings and a transmission pad that absorb wear and vibration. During a rebuild it's wise to check the oil level and filter, valve seals and solenoid operation at the same time — an overdrive that engages sluggishly is just as often caused by low or contaminated oil as by worn internal parts.
