ZF 4651.131.005 OIL DIPSTICK for WG100 | OEM Genuine Part

Overview

The ZF 4651.131.005 OIL DIPSTICK is a precision-engineered fluid level indicator specifically designed for the WG 100 series of automatic transmissions. This OEM genuine part, identified by SKU 4651.131.005, mounts directly into the transmission housing to provide accurate oil level readings during service and maintenance. Positioned on the side or top of the transmission case, it allows technicians to verify proper lubrication without disassembly. When paired with a compatible TRANSMISSION HOUSING, this dipstick ensures that the hydraulic system maintains optimal fluid volume for clutch engagement and torque converter operation.

Symptoms of Failure

• Oil leaks around the dipstick tube: A worn or cracked dipstick seal allows transmission fluid to escape, leaving puddles under the vehicle and causing low fluid levels.
• Inaccurate fluid readings leading to gear slipping: When the dipstick markings fade or the stick becomes bent, operators misread fluid levels, resulting in insufficient lubrication and delayed gear engagement.
• Contaminated fluid entry through the dipstick port: A missing or degraded O-ring on the dipstick cap permits dirt and moisture to enter the transmission, accelerating wear on internal components like the HOUSING.
• Difficulty inserting or removing the dipstick: Physical deformation of the dipstick shaft or tube can cause binding, making routine fluid checks frustrating and unreliable.

Technical Specifications

Compatibility

This oil dipstick is engineered for the ZF WG 100 series of transmissions, including models such as the WG180, WG200, and WG210. It also fits select variants of the WG 120 and WG 150 series where the dipstick tube length matches the housing depth. Always verify fitment with your specific transmission serial number, as the dipstick interfaces directly with the HOUSING and requires a proper seal via the included O-RING to prevent leaks.
