Overview
This OEM genuine ZF 2095.005.106 T 7117 L is a precision-engineered component designed for the internal hydraulic control system of heavy-duty ZF transmissions. Specifically, it functions as a valve body or a critical pressure-regulating spool within the transmission’s main control unit. Its primary role is to direct and modulate hydraulic fluid flow to actuate clutch packs and shift elements, ensuring smooth gear engagement under high torque loads. The part number 2095.005.106 is a factory-coded identifier that guarantees exact metallurgical composition and sealing tolerances. Without this unit, the transmission cannot maintain proper line pressure, leading to erratic shifting or complete loss of drive. It is a direct replacement for worn or damaged units in construction machinery drivelines.
Symptoms of Failure
When the ZF 2095.005.106 begins to degrade, operators will notice distinct operational anomalies. Recognizing these signs early can prevent catastrophic transmission damage.
- Delayed or harsh gear engagement: A worn spool or bore within this part causes internal leakage, resulting in a noticeable lag when shifting from Neutral to Drive or Reverse, often accompanied by a jarring clunk.
- Intermittent loss of drive under load: As the part fails to maintain consistent hydraulic pressure, the transmission may suddenly slip or lose power when climbing grades or moving heavy loads, a symptom often searched as “transmission slipping under load construction.”
- Contaminated hydraulic oil with metallic debris: Internal wear of the 2095.005.106 generates fine metal particles. If you find glitter-like shavings in the oil filter or sump magnet, this valve body is a primary suspect.
- Erratic shift patterns or gear hunting: The transmission may randomly shift between gears or fail to hold a selected gear, a condition frequently described as “ZF transmission hunting for gear” in field reports.

Compatibility
This genuine ZF 2095.005.106 is engineered for use in specific heavy-duty transmission platforms commonly found in wheel loaders, graders, and dump trucks. Based on its design and hydraulic flow characteristics, it is compatible with the following ZF transmission models:
- ZF WG180 (all series variants)
- ZF WG200 (including WG200-2 and WG200-3)
- ZF WG210 (early production runs)
- ZF 4WG-200 (four-speed powershift versions)
Note: Always cross-reference your transmission serial number with the OEM parts catalog to confirm fitment, as internal revisions may apply.
