Overview
The ZF 2094.009.035 T 7336 L is an OEM genuine internal component engineered for the hydraulic control and clutch actuation circuit within ZF heavy-duty powershift transmissions. This precision-machined part, identified by SKU 2094.009.035, functions as a critical spool or valve element that directs oil flow to specific clutch packs during gear selection. It sits within the main valve body assembly, which is secured by the 2094101017: TRANSMISSION HOUSING. Without this component, the transmission cannot maintain proper line pressure or execute smooth directional shifts, making it essential for operational reliability in construction machinery.
Symptoms of Failure
- Delayed or harsh engagement when shifting from forward to reverse: A worn 2094.009.035 causes sluggish clutch fill times, leading to jarring shifts that stress driveline components.
- Intermittent loss of drive under load: As the part wears, internal leakage increases, resulting in pressure drops that cause the machine to stall or fail to move on inclines.
- Visible hydraulic oil seepage around the valve body cover: Degraded sealing surfaces allow ATF to escape, often pooling near the 0636302008: SCREW PLUG and gasket interfaces.
- Erratic shift patterns or neutral creep: Internal scoring prevents the spool from centering correctly, causing unintended clutch engagement and transmission overheating.

Compatibility
This OEM genuine part is designed for integration into ZF’s modular powershift transmission family, specifically the WG180, WG200, and WG210 series. It is also found in select WG150 and WG160 models used in wheel loaders and graders. The 2094.009.035 interfaces directly with the 2094301069: HOUSING and the 2094298054: HOUSING to form a sealed control gallery. Always verify your transmission serial number against ZF documentation before ordering.
