Filling Plug

The BERT TRANSMISSIONS Filling Plug (Part Number 68) is a precision steel fill plug engineered for late-model BERT transmission systems. This Allen-head design delivers straightforward access to transmission fluid levels and replenishment, making it an essential maintenance component for transmission builders and high-performance transmission technicians working with BERT racing transmissions.

Manufactured from steel with cadmium plating, this fill plug resists corrosion and provides secure fastening with its recessed Allen-head socket design. The compact dimensions (1.6 x 0.3 x 2.5 inches) and minimal weight (0.01 lbs) ensure the plug integrates seamlessly into tight transmission pan configurations without adding unnecessary bulk. The cadmium finish offers reliable protection in both shop and racing environments, maintaining integrity across thermal cycling and repeated service intervals typical of transmission rebuilds and race applications.

This plug is designed for transmission technicians and builders who require OEM-level component accuracy when servicing BERT late-model transmissions. Whether performing routine fluid checks, maintenance intervals, or transmission rebuilds, having the correct factory-spec fill plug ensures proper pan sealing and eliminates the need for aftermarket substitutes. The Allen-head configuration allows quick engagement with standard hex keys, streamlining service workflows and reducing downtime during transmission work.

BERT transmissions are recognized throughout the racing and performance automotive community for their durability and precision engineering. Pairing genuine BERT service components like this filling plug ensures compatibility and maintains the integrity of your transmission system.
