Firepunk Diesel started with very humble beginnings in 2009. Lavon built transmissions in his free-time in the old milking parlor at the Kauffman Farm in rural Plain City. Initially, Lavon was a one-man operation. He removed the transmissions, rebuilt and reinstalled the transmissions in one day. As word spread of the quality of product Lavon was producing, he brought in Matt Kauffman to help work on the trucks, and his brother, Lyn, to help with customer builds and fabrication. All of this work was done in a small 20×30 tool shed on the Kauffman Farm property.

In 2013, the opportunity presented itself for Firepunk to move to their current location on Lafayette-Plain City Road. Since the move to our current location, Firepunk Diesel has grown to over 25 employees, a full-service shop, custom fabrication shop, powder coating services and continues to provide quality Dodge Ram Transmissions for any customer need.

Our company is based on the core values of taking care of our customers like they are family, providing a reliable and quality product for customers and providing an exceptional environment for our employees to thrive.

Highly recommend
Got their Towmaster trans for my 2000 Cummins. Great service, flawless delivery and core return. Installed myself so I called with a few questions and they were quick to respond and very helpful. Just made the maiden towing voyage and man, this trans performed flawlessly and it shifts like an absolute dream. Highly recommend Firepunk!

Bullet proofed the Trans
My grandson took his 04 ram there. They bullet proofed the Trans which was hurt. Turned up the pump. This truck is fast and pulls our 5000lb travel trailer like it wasn't there.. I kept looking back to see if was still there.
