Overview
The ZF 0730.101.208 ADJUSTMENT PLATE is a precision-machined shim component engineered for the WG 200 Series and WG 65 Series transmissions. This OEM genuine part functions as a critical spacer within the clutch pack assembly, ensuring correct axial clearance and hydraulic piston travel. Proper adjustment via this plate directly influences shift quality and torque transfer efficiency. The SKU 0730.101.208 is laser-etched on the component for immediate verification during rebuilds. When installed alongside a TRANSMISSION HOUSING, this plate maintains the exact stack height required for optimal gear engagement.
Symptoms of Failure
- Delayed gear engagement under load: A worn or incorrectly selected adjustment plate causes insufficient clutch pack compression, leading to hesitation when shifting from neutral to drive or reverse.
- Intermittent transmission slipping: As the plate wears or deforms, hydraulic pressure cannot fully lock the clutch discs, resulting in RPM flare without corresponding vehicle acceleration.
- Low hydraulic pressure codes: Excessive clearance from a degraded adjustment plate triggers pressure loss across the clutch circuit, often logged as diagnostic trouble codes in electronic control units.
- Metallic debris in transmission fluid: Friction between the plate and adjacent components generates fine steel particles, visible during fluid changes or filter inspections.

Compatibility
This adjustment plate is designed for the ZF WG 65 Series and WG 200 Series transmissions. It directly fits the following models: WG65, WG180, WG200, and WG210. The plate is also compatible with certain variants of the Ecomat 4HP and 5HP series when used in conjunction with the correct HEXAGON SCREW (M8 x 25) for secure mounting. Always verify stack height using a depth micrometer after installation, and replace the HEXAGON SCREW (M10 x 30) and HEXAGON SCREW (M12 x 35) to prevent fastener fatigue.
