Overview
The ZF 4642.301.168 SCREEN SHEET is a critical filtration component engineered for the WG 150 Series transmission. This OEM genuine part sits within the oil sump or hydraulic circuit, where it captures metallic debris and contaminants before they can circulate through the valve body and clutch packs. By maintaining fluid cleanliness, the screen sheet ensures consistent hydraulic pressure and extends the service life of adjacent assemblies, such as the 4642101108: TRANSMISSION HOUSING and the 4642301208: TRANSMISSION HOUSING. The SKU 4642.301.168 is a direct replacement for the original factory-installed mesh, guaranteeing precise fitment and filtration efficiency.
Symptoms of Failure
- Erratic shifting or gear slipping: A clogged screen sheet restricts oil flow, causing delayed engagement or harsh shifts under load.
- Low transmission oil pressure warnings: Debris accumulation on the mesh reduces pump suction, triggering dashboard alerts or diagnostic trouble codes.
- Overheating during operation: Restricted fluid circulation forces the transmission to run hotter than normal, accelerating wear on seals and bearings.
- Whining or humming noise from the sump: Starvation of the oil pump due to a blocked screen creates audible cavitation sounds.

Compatibility
This screen sheet is specifically validated for the ZF WG 150 Series. It is also compatible with the WG 180 and WG 200 models that share the same oil sump architecture. For applications requiring a different mesh density, consider the 4642301169: SCREEN SHEET or the 4642301186: SCREEN SHEET. Always verify fitment with your transmission’s serial number before installation. When replacing the screen, it is recommended to also inspect the 0730365125: TYPE PLATE for legibility and the 0631311009: GROOVED STUD for thread condition.
