Overview
The ZF 6057.018.107 CONTROL UNIT is a critical electro-hydraulic interface within the WG211 series powershift transmission. This OEM genuine part governs shift timing, clutch pressure modulation, and torque converter lock-up logic. Positioned directly atop the main valve body, the control unit receives electronic signals from the vehicle’s ECU and converts them into precise hydraulic commands. The SKU 6057.018.107 is engineered to exact ZF tolerances, ensuring seamless communication between the transmission’s mechanical components and its electronic brain. When paired with a robust TRANSMISSION HOUSING, the control unit forms the central nervous system of the drivetrain, dictating shift quality and overall durability.
Symptoms of Failure
- Erratic or delayed shifting: A failing control unit often causes harsh engagement or hesitation between gears, particularly under load. This “ZF transmission shift hesitation” is a common search query for WG211 operators.
- Intermittent loss of forward or reverse: When the unit’s solenoid driver circuits degrade, the transmission may suddenly drop into neutral, requiring a full system reset.
- Torque converter shudder: Faulty pressure regulation from the 6057.018.107 can produce a vibration during lock-up, often misdiagnosed as a mechanical converter issue.
- Diagnostic trouble codes (DTCs) for solenoid circuits: Persistent P07xx or P27xx codes related to shift solenoid performance directly point to control unit degradation.

Compatibility
This control unit is specifically designed for the ZF WG211 series, but its architecture is shared across the WG180, WG200, and WG250 families. It directly interfaces with the HOUS.FRONT SECT and the HOUSING REAR PART to create a sealed hydraulic circuit. For proper mechanical alignment, the unit mounts using a CYLINDRICAL PIN that ensures zero play during vibration. Always verify your transmission’s serial number prefix (e.g., WG211-xxxx) before ordering, as early production runs used a different connector pinout.
