Overview
The ZF 4616.301.252 CONVERTER COVER is a critical structural component designed for the WG 65 Series transmission family. This OEM genuine part encloses the torque converter assembly, protecting internal hydraulic components from contamination while maintaining precise oil flow and pressure within the converter housing. The SKU 4616.301.252 serves as the primary interface between the engine bell housing and the transmission casing, ensuring correct alignment of the converter pump and turbine assembly. Without this cover, the transmission cannot maintain proper fluid coupling or withstand the torsional forces generated during heavy-duty operation.
Symptoms of Failure
When the 4616.301.252 CONVERTER COVER begins to wear or crack, operators may notice these specific failure indicators:
- Torque converter oil leaks at the bell housing – A worn cover gasket surface or hairline fracture allows transmission fluid to escape, leaving puddles under the vehicle.
- Gear slipping under load – A distorted cover reduces converter clutch engagement pressure, causing the transmission to slip during acceleration or hill climbs.
- Excessive converter housing vibration – A warped or cracked cover disrupts the balance of the rotating assembly, leading to driveline shudder at specific RPM ranges.
- Contaminated transmission fluid – A compromised seal allows dirt and moisture to enter the converter cavity, accelerating wear on internal components.
