1947 - 2026

My father started this business back in 1947. He worked on anything that would fit through the front door of our shop, and some in the driveway that couldn’t. Back then, we did everything from overhauling a carburetor on an 8N Ford tractor to rebuilding an injection pump on a GM diesel. When my brother and I bought the business from Dad in 1978, we started specializing in automatic transmissions, torque converters, electronic fuel injection, and chassis dynamometer testing.

Super Stock Double Disc Torque Converter

Ford 6R140

A completely brand new torque converter, engineered as a stock replacement for use with stock application vehicles. Designed in-house. Every converter is built with consistency and quality control in mind. Each converter is automatically balanced and undergoes dynamometer testing to verify converter operation and lockup function before it leaves the production line. Additional quality-control checks verify critical characteristics such as runout, assembled height, and leak integrity. The result is a thoroughly tested, ready-to-install torque converter designed to provide dependable performance.
