Overview
This OEM genuine ZF 2095.028.007 T 7113 L is a critical hydraulic control component engineered for the valve body assembly within ZF heavy-duty powershift transmissions. It precisely directs oil flow to modulate clutch engagement, ensuring smooth gear changes under extreme torque loads in construction machinery. The SKU 2095.028.007 is a factory-sealed part, guaranteeing exact fit and original material composition. When installed, it interfaces directly with the 2095101028: TRANSMISSION HOUSING and the 2095301034: TRANSMISSION HOUSING to maintain hydraulic circuit integrity.
Symptoms of Failure
- Erratic gear engagement or delayed shifting: A worn 2095.028.007 spool or bore causes internal leakage, leading to sluggish clutch fill times and harsh shifts under load.
- Transmission overheating during operation: When this valve fails to regulate pressure, continuous slippage generates excessive heat, often mistaken for cooler issues.
- Low hydraulic pressure at test ports: Internal bypass past the valve seat results in a 15-20% pressure drop, triggering warning codes on the machine’s ECU.
- Oil contamination from metallic debris: As the hardened steel surface wears, fine particles circulate, accelerating damage to the 0634306189: O-RING and adjacent seals.

Compatibility
This valve is a direct replacement for ZF WG180, WG200, and WG210 series powershift transmissions commonly found in wheel loaders, dozers, and graders. It also fits select 4WG-200 and 6WG-200 variants used in articulated dump trucks. Always verify the housing casting number; the 4475280150: SCREW PLUG must be torqued to 45 Nm during reinstallation to prevent cross-threading in the bore.
