Gearbox Volvo 1800 (BW35)

Delayed shifts, slipping or jerky power transfer can point to dirt and low hydraulic pressure in the BW35 transmission's control system, and the Hydraulic filter ZF22 is then one of the first checkpoints. This category gathers wear and service parts for exactly the hydraulic control in the Borg-Warner BW35 automatic on the Volvo 1800.

The group includes Hydraulic filter ZF22 units that trap particles before the oil reaches the valve housing, balls that belong to the hydraulic valve functions, and screws for mounting. When going through the transmission, clean oil, an undamaged strainer and correctly tightened fasteners are typical things to check. Since the parts are specific to the BW35 version, it is worth confirming that your 1800 really has an automatic transmission before ordering.
