Overview
The ZF 4681.054.014 4 BP 210 BASICPOWER Transmission Assembly represents a complete, drop-in replacement unit engineered for the BP 210 and BP 230 series of powershift transmissions. This assembly integrates the torque converter, clutch packs, and planetary gear sets into a single, pre-assembled module, drastically reducing installation time compared to rebuilding a worn unit. As a fully assembled “complete unit,” the SKU 4681.054.014 eliminates the guesswork of sourcing individual components, ensuring precise hydraulic and mechanical alignment from the first shift. It sits as the core power transfer assembly within the transmission housing, directly managing gear engagement and torque multiplication for medium-duty construction and agricultural vehicles.
Symptoms of Failure
When the ZF 4681.054.014 assembly begins to degrade, operators often notice specific performance declines. Recognizing these signs early can prevent catastrophic drivetrain damage and costly downtime.
- Delayed or harsh engagement when shifting from neutral to drive: A worn clutch pack or degraded seals inside the assembly cause a noticeable lag or a jarring “clunk” as hydraulic pressure builds unevenly.
- Progressive gear slippage under load: The transmission may rev higher than expected without a corresponding increase in vehicle speed, particularly when climbing grades or carrying heavy payloads. This indicates internal friction material wear.
- Dark, burnt-smelling transmission fluid with metallic particles: Inspecting the dipstick reveals fluid that has turned from red to dark brown or black, often accompanied by a distinct burnt odor. Fine metallic glitter in the fluid signals advanced wear of bearings or clutch plates.
- Constant low hydraulic pressure warnings or erratic shifting: The assembly’s internal valve body or pump may fail to maintain consistent pressure, leading to random gear hunting or failure to hold a selected gear.

Compatibility
This complete assembly is designed for direct integration into specific ZF transmission models that utilize the BP 210 and BP 230 modular architecture. It is a primary service part for the following transmission series:
- ZF WG180 (all variants, including WG180C and WG180E)
- ZF WG200 (all variants, including WG200C and WG200E)
- ZF 4 BP 210 (BASICPOWER series)
- ZF 4 BP 230 (BASICPOWER series)
While these are the most common applications, the 4681.054.014 may also fit select ZF 4 WG-210 and ZF 4 WG-230 models produced after 2005. Always verify the transmission model tag and current serial number before ordering to ensure correct fitment. Cross-reference your existing unit’s part number against the OEM reference listed in the specifications table above.
