Overview
The ZF 4168.030.119 CONVERTER Torque Converter Assembly is a complete, direct-replacement unit engineered for the WG 150 Series transmission family. This critical component sits between the engine flywheel and the transmission input shaft, converting engine torque into hydraulic energy to drive the planetary gearset. The SKU 4168.030.119 is a fully assembled torque converter, including the impeller, turbine, stator, and lock-up clutch, designed to restore original shift quality and power transfer efficiency. When installed alongside the 4642101109 TRANSMISSION HOUSING and 4642301205 TRANSMISSION HOUSING, this assembly ensures precise alignment and hydraulic sealing within the transmission case.
Symptoms of Failure
When the ZF 4168.030.119 torque converter wears out, operators typically notice three to four distinct failure symptoms. First, shuddering during lock-up engagement occurs as the clutch friction material degrades, causing vibration under light throttle. Second, delayed or harsh gear engagement results from reduced hydraulic pressure inside the converter, often accompanied by a whining noise. Third, transmission fluid overheating happens when the stator one-way clutch fails, reducing torque multiplication and generating excess heat. Fourth, visible oil leaks from the bell housing area indicate a failed converter hub seal or cracked weld, requiring immediate replacement to avoid internal damage.

Compatibility
This torque converter assembly is primarily designed for the ZF WG 150 Series transmissions, including models WG150, WG151, WG152, and WG153. It also fits select variants of the WG180 and WG200 series when used with the correct adapter plate. The 4168.030.119 unit is not compatible with older ZF 4HP or 5HP automatic transmissions. For proper installation, ensure the transmission housing is in good condition; consider replacing the 0730365125 TYPE PLATE for accurate identification and the 0631311009 GROOVED STUD for secure mounting.
