Texas Diesel Company is 22 miles south of Denison on US-75 — about a 25-minute drive to our shop in Van Alstyne. Denison sits at the north end of the corridor we work, and we serve a steady base of customers from there for repair, performance, and custom build work.
Why Denison residents come to us
Denison is a meaningful diesel town — the combination of manufacturing, agriculture, and the Lake Texoma marine and recreational industry creates real demand for specialized diesel service. The local options for diesel-specific work are limited, and the dealer service centers in the area can have long wait times for non-warranty work.
We provide full Ford / GM / Dodge factory diagnostic capability without the dealer wait, with shorter typical scheduling and a real focus on getting the diagnosis right the first time. The 25-minute drive south is what most Denison customers trade for the better outcome.
Who we serve in Denison
- Manufacturing fleet — Denison and the surrounding area have manufacturing employers running diesel support fleets
- Lake Texoma marine and recreational — diesel tow vehicles, boat haulers, and recreational fleet that support the lake’s tourism and recreation economy
- Construction and trades — work trucks for the area’s continued development
- Agriculture — Grayson County still has working farms and ranches
- Daily drivers — Denison residents whose diesel is their primary household vehicle
