Our Story
We opened our doors at 178 Eugene Rd, Eugene, MO, to provide top-notch but affordable services on Dodge diesel transmissions and quickly earned a reputation for in-house mastery.
But it’s not just about transmissions—we handle Diesel Repair and Custom Turbos too. If it runs on diesel, we’re ready to make it stronger, faster, and more reliable than you ever thought possible.
