Truman H. Dunn (above) was a mechanic at Camp Fannin during World War II. While he was working for the Army, he learned about a new concept just released on new cars: the automatic transmission. Mr. Dunn opened a small garage at his home and spent his time off from the Army working on cars. When the war was over, Mr. Dunn began to specialize in the still-new automatic transmission, calling his business Dunn's Transmission Shop. In the '50s, Mr. Dunn bought a lot on Gaston Street and moved his repair business to our current location.

Ewell Dickerson(above/below with wife Sue),a long-time employee, bought Dunn Transmissions in 1968. Under his ownership, the shop has continued to grow  through the years to include the entire 1400 block of West Erwin and to employ more than 20 East Texans. In 2005, his son David Dickerson became manager of the company and is responsible for its day-to-day operation. Ewell is still active in the business.
