The Austin Metro was first introduced in October 1980 and was initially only on sale to the UK market, export sales to the European market following in early 1981. The 998 cc and 1275 cc engines are fitted, with low compression and economy versions available. The body is of computer-based design and is assembled and welded by computer-controlled robots. The “A-Plus” engine and gearbox assembly is similar to that fitted to the Mini range, although it is much improved, with durability and economy prime considerations. Drive is through the front wheels and the engine/gearbox unit is fitted transversely across the front of the car.
The heart of the Laycock de Normanville overdrive is the hydraulic system. Inside the overdrive case is a small pump that is driven by a cam on the main shaft. The pump produces 450-500 psi of hydraulic pressure. If the system is not well maintained properly or contaminants or dirt are introduced during a rebuild the car owner is asking for trouble. Small dirt particles can foul and block tiny hydraulic passages in the system.
