Overview
The ZF 0501.212.784 SEAL KIT is a critical OEM genuine maintenance component designed to restore hydraulic integrity within ZF WG-series transmissions. This kit contains all necessary elastomeric seals, gaskets, and O-rings required to reseal the valve body and clutch piston areas. The SKU 0501.212.784 is specifically engineered to prevent cross-contamination between oil circuits, ensuring precise shift timing and pressure retention. When installed alongside a TRANSMISSION HOUSING, this seal kit guarantees a leak-free interface between stationary and rotating assemblies.
Symptoms of Failure
- External oil seepage at transmission housing seams: Worn seals in the 0501.212.784 kit allow ATF to escape, leaving visible drips under the bellhousing or pan rail.
- Delayed or harsh gear engagement: Internal seal degradation causes pressure loss, leading to “flare shifts” or a 2-3 second delay when selecting Drive or Reverse.
- Erratic shift quality under load: When seals fail, the transmission may hunt between gears or slip during uphill climbs, particularly in WG110 and WG115 units.
- Low fluid level without external leaks: Internal seal failure can allow fluid to bypass into the torque converter housing, causing mysterious fluid consumption.

Compatibility
This seal kit is engineered for the WG110, WG115, WG130, and WG160 series transmissions. It also fits select WG180 and WG200 variants when used with a HOUSING adapter. The kit is not recommended for pre-1990 WG models without verifying the O-RING cross-section. For WG200 applications, pairing this kit with a HOUSING ensures proper sealing of the main control bore.
