ZF 2094.009.012 T 7336 PS | OEM Genuine Part

Overview

The ZF 2094.009.012 T 7336 PS is an OEM genuine pressure switch assembly designed to monitor hydraulic pressure within ZF powershift transmissions. Positioned within the valve body or control module, this part sends critical pressure signals to the transmission control unit (TCU) to ensure proper clutch engagement and shift timing. The SKU 2094.009.012 is a direct replacement for original equipment, guaranteeing factory-specified performance in demanding construction machinery applications. When paired with a robust TRANSMISSION HOUSING, this switch maintains the integrity of the hydraulic circuit, preventing erratic shifting under heavy loads.

Symptoms of Failure

• Delayed or harsh gear engagement: A failing 2094.009.012 can cause sluggish clutch pack fill, leading to jarring shifts during operation.
• Intermittent loss of forward or reverse: Worn internal contacts may trigger false pressure readings, causing the transmission to default to neutral unexpectedly.
• Hydraulic fluid seepage at the switch port: Degraded seals allow oil to weep past the threads, often visible as wetness on the HOUSING.
• Illuminated warning lamp or error code: The TCU logs pressure-related fault codes (e.g., P0841) when the switch fails to send a consistent signal.

Technical Specifications

Compatibility

This pressure switch is engineered for ZF WG series transmissions commonly found in wheel loaders, graders, and telehandlers. It directly fits the WG180, WG200, and WG210 models. The part also integrates with the HOUSING assembly used in older 4WG-200 variants. For proper sealing during installation, always replace the SCREW PLUG and O-ring to prevent contamination ingress.
