ZF 4681.303.010 SCREEN SHEET for WG190/WG210 | OEM Genuine Part

Overview

The ZF 4681.303.010 SCREEN SHEET is a critical filtration component engineered for the WG190 and WG210 series transmissions. This OEM genuine part, identified by SKU 4681.303.010, sits within the transmission’s hydraulic circuit, specifically positioned between the valve body and the main housing. Its primary function is to capture metallic debris, clutch wear particles, and other contaminants from the transmission fluid before they can circulate through sensitive components like the torque converter and clutch packs. By maintaining fluid cleanliness, this screen sheet ensures consistent hydraulic pressure and prolongs the service life of the entire assembly. It works in conjunction with the TRANSMISSION HOUSING to create a sealed, debris-free environment for optimal gear engagement.

Symptoms of Failure

• Erratic gear engagement or delayed shifting: A clogged screen sheet restricts fluid flow, causing hesitation when shifting between forward and reverse gears, particularly under load.
• Intermittent transmission overheating: Contaminated fluid bypassing a damaged screen sheet can cause the transmission to run hotter than normal, triggering warning lights or thermal shutdown.
• Whining or humming noise from the pump: When the screen sheet becomes blocked, the hydraulic pump works harder to draw fluid, producing a distinct high-pitched whine that intensifies with engine RPM.
• Visible metal particles in the oil pan: If the screen sheet tears or degrades, metallic shavings will appear in the drained fluid, indicating that internal wear is no longer being filtered effectively.

Technical Specifications

Compatibility

This screen sheet is specifically designed for ZF WG series transmissions, with primary application in the WG190 and WG210 models. It is also compatible with the WG180 and WG200 series when used in conjunction with the correct HOUS.FRONT SECT and HOUSING REAR PART. For applications requiring a different rear section configuration, verify fitment with the HOUSING REAR SECTION. Always confirm your transmission’s serial number against ZF’s compatibility charts before installation.

Frequently Asked Questions

Q: How often should the ZF 4681.303.010 screen sheet be replaced?
A: ZF recommends replacing this screen sheet during every major transmission overhaul or when performing a fluid change after a clutch failure. For normal preventive maintenance, inspect the screen sheet every 500 operating hours or 12 months, whichever comes first.

Q: Can I clean and reuse the screen sheet instead of replacing it?
A: While the stainless steel mesh can be cleaned with solvent, ZF does not recommend reusing the screen sheet due to potential micro-tears or deformation from repeated thermal cycling. Always install a new OEM genuine part (4681.303.010) to ensure proper filtration and avoid warranty issues.

Q: Will this screen sheet fit the WG180 transmission without modification?
A: The 4681.303.010 is directly compatible with WG180 models only when used with the correct HOUS.FRONT SECT. For WG180 units with a different housing configuration, you may need the 4681301016 screen sheet variant instead.
