Ford C4 Modulator Plug Push In

By Popular Demand, Dynamic Racing Transmissions has designed a aluminum plug to replace the stock vacuum modulator on Ford C4's with a push in unit.

Each plug is made in-house and utilizes the factory o-ring for sealing and is held in place with the factory metal spring clamp.

A modulator plug is necessary when upgrading to any of our manual valve bodies, as the stock vacuum modulator is no longer needed.

Each plug includes a new o-ring and is a simple changeout for the stock modulator.
