ZF 4616.101.102 TRANSMISSION HOUSING for WG65 | OEM Genuine Part

Overview

The ZF 4616.101.102 TRANSMISSION HOUSING is the central structural core of the WG65 series gearbox. This OEM genuine part encases the planetary gear sets, valve body, and torque converter assembly, providing precise alignment and protection against external contaminants. As the main load-bearing component, it ensures that all internal rotating elements remain correctly spaced under high-torque conditions. The SKU 4616.101.102 is manufactured to ZF’s original specifications, guaranteeing exact fitment and material integrity for industrial driveline applications.

Symptoms of Failure

• External oil seepage around mating surfaces: A cracked or warped housing often leads to transmission fluid leaking from the bell housing or side cover joints, visible as dark stains on the casing.
• Abnormal gear engagement noise: When the housing loses dimensional stability, bearing bores become misaligned, causing a distinct whining or grinding sound during shifts under load.
• Persistent low fluid level without visible external leaks: Internal cracks can allow oil to migrate into the torque converter cavity, resulting in unexplained fluid loss and eventual gear slipping.
• Vibration during acceleration: A fractured housing mount or bolt boss allows the transmission to shift relative to the engine, creating driveline shudder at specific RPM ranges.

Technical Specifications

Compatibility

This housing is engineered specifically for the ZF WG65 series, but it also fits select models in the WG180, WG200, and WG250 families when used with the correct adapter kit. It is commonly found in off-highway trucks, wheel loaders, and industrial material handlers built between 2005 and 2020. Always verify your transmission’s serial number against ZF’s application guide before ordering.
