Filling Plug

The Filling Plug (Part Number 68) is a precision steel fill plug designed for late-model BERT transmission systems. This component is essential for maintenance tasks performed by transmission builders and technicians, ensuring proper fluid levels and replenishment. Its design allows for straightforward access, making it a valuable tool for anyone working with these transmission systems.

Manufactured from steel and featuring a cadmium plating, this fill plug is resistant to corrosion and provides secure fastening through its recessed Allen-head socket design. The compact dimensions (1.6 x 0.3 x 2.5 inches) and minimal weight (0.01 lbs) allow it to fit seamlessly into tight configurations without adding unnecessary bulk. The cadmium finish ensures reliable protection in various environments, maintaining integrity during thermal cycling and repeated service intervals.

This plug is ideal for transmission technicians and builders who require OEM-level component accuracy when servicing late-model transmissions. Whether performing routine fluid checks or complete rebuilds, having the correct factory-spec fill plug is crucial for proper pan sealing and avoiding the need for aftermarket substitutes. The Allen-head configuration facilitates quick engagement with standard hex keys, streamlining service workflows and minimizing downtime.
