ZF 4644.321.241 PLATE for WG200 | OEM Genuine Part

Overview

The ZF 4644.321.241 PLATE is a precision-engineered component designed for the WG200 series transmission. This genuine OEM part functions as a critical sealing and load-distribution element within the clutch pack assembly, ensuring proper hydraulic pressure retention and torque transfer between rotating elements. The SKU 4644.321.241 is manufactured to exact ZF tolerances, preventing fluid bypass and maintaining consistent gear engagement under high-torque conditions. Installed directly against the TRANSMISSION HOUSING, this plate works in concert with the HOUSING to create a sealed chamber for hydraulic actuation.

Symptoms of Failure

• Erratic gear engagement and delayed shifting – When the 4644.321.241 plate warps or develops surface scoring, hydraulic pressure drops, causing “ZF WG200 transmission slipping under load” scenarios.
• Transmission fluid leaks near the bell housing – A cracked plate allows ATF to bypass seals, leading to “ZF transmission oil leak from clutch housing” conditions that require immediate attention.
• Burning clutch smell during operation – Insufficient plate flatness causes clutch pack slippage, generating excessive heat and a distinct “burning transmission fluid odor” during acceleration.
• Harsh or clunking shifts between gears – Distorted plates prevent smooth hydraulic modulation, resulting in “ZF WG200 hard shifting from 2nd to 3rd gear” complaints from operators.

Technical Specifications

Compatibility

This genuine ZF plate is primarily engineered for the WG200 series transmissions, including models WG180, WG200, and WG210. It is also compatible with select ZF Ecomat 4HP and 5HP variants that share the same clutch pack architecture. The 4644.321.241 plate interfaces directly with the GROOVED STUD for precise alignment and is secured beneath the TYPE PLATE for identification purposes. Always verify your transmission serial number before ordering to ensure correct fitment.
