ZF 0730.100.904 ADJUSTMENT PLATE for WG200 | OEM Genuine Part

Overview

The ZF 0730.100.904 ADJUSTMENT PLATE is a precision-machined OEM genuine component engineered specifically for the WG200 series transmission. This plate serves as a critical shim and alignment interface within the hydraulic control assembly, ensuring correct end-play tolerances and oil flow regulation between the valve body and the TRANSMISSION HOUSING. By maintaining precise axial clearance, the adjustment plate prevents internal pressure loss and ensures consistent clutch engagement. The SKU 0730.100.904 is manufactured to ZF’s original factory specifications, guaranteeing a direct fit without modification.

Symptoms of Failure

• Erratic gear engagement and delayed shifts: A worn adjustment plate alters hydraulic pressure, causing “ZF WG200 transmission slipping when hot” or harsh upshifts.
• Internal oil leaks and low fluid pressure: Degradation of the plate’s sealing surface leads to “transmission fluid leaking from bell housing” or “low line pressure on ZF WG200”.
• Abnormal noise during torque converter lockup: Incorrect clearance from a fatigued plate produces a “whining noise from ZF transmission under load”.
• Intermittent loss of drive in forward gears: Misalignment caused by a warped plate results in “WG200 transmission won’t engage reverse” or “delayed forward engagement”.

Technical Specifications

Compatibility

This adjustment plate is primarily designed for the ZF WG200 series, including models WG200, WG180, and WG210. It is also compatible with select ZF Ecomat 4HP and 5HP variants that share the same hydraulic control architecture. Always verify the part number 0730.100.904 against your transmission’s serial plate before installation. For full disassembly, the DISCONNECTION tool is required to separate the valve body, and replacement of the OUTPUT FLANGE or OUTPUT FLANGE is often recommended during major overhauls.
