ZF 0501.339.566 CODE LABEL | OEM Genuine Part

Overview

The ZF 0501.339.566 CODE LABEL is a critical identification component for heavy-duty construction machinery transmissions. This OEM genuine part ensures that the transmission control unit (TCU) correctly interprets the specific software configuration and hardware variant of your ZF gearbox. Mounted directly on the transmission housing, the code label provides a unique alphanumeric signature that the system reads during startup. The SKU 0501.339.566 corresponds to a factory-programmed label that matches the exact calibration of your unit. Without this label, the transmission may default to a generic map, leading to suboptimal shift timing and reduced torque management. It is typically installed adjacent to the 4699101108: HOUSING and works in conjunction with the 4699102172: INPUT shaft sensor to verify gear ratios.

Symptoms of Failure

• Transmission fails to shift into correct gear range – When the code label is damaged or delaminated, the TCU cannot verify the transmission model, causing erratic shifting or limp-home mode.
• Persistent “Transmission Configuration Error” on display – A common long-tail search query is “ZF code label error code after rebuild,” which points directly to a missing or illegible 0501.339.566 label.
• Incorrect torque converter lockup timing – The label provides the base calibration data; without it, the converter may lock too early or too late, reducing fuel efficiency.
• Intermittent loss of communication with the 4699001237: GK10LD gear kit – The label acts as a bridge between the mechanical assembly and the electronic controller; failure here can mimic sensor faults.

Technical Specifications

Compatibility

This code label is designed for ZF transmissions commonly found in construction machinery, including the WG180, WG200, and WG211 series. It is also compatible with the 4699103057: OUTPUT shaft variants used in telehandlers and wheel loaders. The label is pre-programmed for specific transmission ratios and must match the original equipment specification. Always verify the label against the transmission serial number before installation.
