ZF 6073.003.014 CONTROL UNIT for WG94 | OEM Genuine Part

Overview

The ZF 6073.003.014 CONTROL UNIT is a precision-engineered electronic assembly designed specifically for the WG 94 Series powershift transmission. This OEM genuine part manages hydraulic valve actuation and shift timing, ensuring smooth gear engagement under heavy load conditions. Positioned within the transmission valve body, the control unit interprets input signals to regulate clutch pressure and torque converter lockup. The SKU 6073.003.014 is a direct replacement for factory-installed units, maintaining original ZF performance standards.

Symptoms of Failure

• Erratic shifting or delayed engagement – When the control unit degrades, the transmission may hesitate before shifting or exhibit harsh gear changes, especially during low-speed maneuvers.
• Intermittent loss of forward or reverse gears – A failing unit can cause sudden neutral conditions, leaving the operator unable to move the vehicle until the system resets.
• Transmission warning lamp illumination – The onboard diagnostics will trigger a fault code related to solenoid circuit malfunctions, often accompanied by reduced power mode.
• Oil contamination in electrical connectors – Internal seal failure allows transmission fluid to migrate into the control unit harness, causing corrosion and short circuits.
