Overview
The ZF 4642.301.169 SCREEN SHEET is a critical filtration component engineered for the WG 150 transmission series. Positioned within the oil sump or hydraulic circuit, this genuine OEM part captures metallic debris, clutch wear particles, and contaminants before they can circulate through the valve body and torque converter. By maintaining fluid cleanliness, the screen sheet ensures consistent hydraulic pressure and protects precision-machined surfaces from abrasive damage. The SKU 4642.301.169 is a direct replacement designed to restore original filtration efficiency and extend transmission service life.
Symptoms of Failure
- Erratic shifting or delayed engagement: A clogged screen sheet restricts oil flow, causing hesitation when shifting between forward and reverse gears.
- Intermittent loss of hydraulic pressure: Debris accumulation on the screen reduces pump suction, leading to fluctuating pressure readings on diagnostic tools.
- Overheating transmission fluid: Restricted flow through the screen forces the transmission to work harder, generating excess heat that can degrade seals and clutches.
- Whining or groaning noises from the sump: As the screen becomes blocked, cavitation occurs in the pump, producing audible sounds during acceleration.

Compatibility
This screen sheet is primarily designed for the ZF WG 150 series, but it also fits select variants of the WG 180 and WG 200 transmissions when used with the correct TRANSMISSION HOUSING (4642101108) or TRANSMISSION HOUSING (4642301208). Always verify the mounting flange dimensions against your existing assembly. For proper identification, the TYPE PLATE (0730365125) provides the exact model code, while the GROOVED STUD (0631311009) secures the screen in position during installation.
