Overview
The ZF 4616.306.104 INTERMEDIATE PLATE is a critical structural component within the WG65 series transmission. Positioned between the main gear sets and the output shaft assembly, this OEM genuine part acts as a precision-machined separator and bearing support surface. It ensures correct axial alignment of planetary gears and distributes hydraulic pressure within the clutch packs. The SKU 4616.306.104 is manufactured to ZF’s exacting tolerances, making it essential for maintaining the integrity of the entire drivetrain. When replacing this plate, it is common to also inspect the 4616105413 OUTPUT and the 4616203017 OUTPUT FLANGE for wear, as these components share the same load path.
Symptoms of Failure
- Delayed or harsh gear engagement: A warped intermediate plate causes improper clutch pack clearance, leading to a noticeable lag when shifting from Neutral to Drive or Reverse.
- Low hydraulic pressure and slipping: Cracks or scoring on the plate surface allow internal fluid to bypass seals, resulting in pressure drops and transmission slip under load.
- Metallic debris in the oil pan: As the plate wears, fine steel particles shed into the transmission fluid, often visible during routine oil changes.
- Vibration during acceleration: Misalignment caused by a fatigued intermediate plate creates driveline shudder, particularly in the 2nd to 3rd gear range.

Compatibility
This intermediate plate is engineered for the ZF WG65 series, but it also fits several related heavy-duty models. It is directly compatible with the WG180, WG200, and WG250 transmissions used in construction and agricultural machinery. The plate’s bolt pattern matches the 4616101117 TRANSMISSION HOUSING, and it is secured using 0636011038 HEXAGON SCREW fasteners. Always verify your transmission serial number before ordering.
