Overview
The ZF 4660.201.002 SCREEN SHEET is a critical filtration component engineered specifically for the WG 98 Series transmission. This OEM genuine part, identified by SKU 4660.201.002, sits within the hydraulic circuit of the transmission, acting as a primary barrier against particulate contaminants. By trapping debris before it enters the valve body and clutch packs, the screen sheet ensures consistent oil flow and protects internal precision components from abrasive wear. This part is typically positioned near the suction side of the oil pump, directly interfacing with the 4660101020: TRANSMISSION HOUSING to maintain a sealed filtration environment.
Symptoms of Failure
When the 4660.201.002 screen sheet becomes clogged or physically damaged, operators may notice distinct operational issues. Common failure symptoms include:
- Erratic gear engagement or delayed shifting – Restricted oil flow due to a blocked screen sheet can cause hesitation when shifting between forward and reverse gears.
- Intermittent transmission overheating – A compromised screen sheet reduces hydraulic efficiency, leading to elevated oil temperatures during normal operation.
- Whining or cavitation noise from the pump – When the screen sheet is obstructed, the pump struggles to draw oil, producing audible distress sounds.
- Contaminated oil visible on the dipstick – A torn screen sheet allows metallic particles to circulate, often visible as glitter in the transmission fluid.
