FAQs

What Areas Do You Serve?

We are located at 12930 IH 10 E, near Loop 1604 in Converse, TX. Our service area extends throughout San Antonio, Schertz, Universal City, Austin, Selma, La Vernia, and New Braunfels, TX. We proudly support commercial drivers and fleets operating within a 60-mile radius.

How Often Should I Service My Transmission?

Most heavy-duty transmissions benefit from a fluid and filter service every 100,000 to 150,000 miles, depending on driving habits and conditions. For trucks hauling in hotter climates like San Antonio, fluid degradation can occur faster, so shorter intervals may be recommended. Regular inspections help prevent slipping, overheating, and complete transmission failure.

What Are Common Signs of a Failing Truck HVAC System?

If your A/C starts blowing warm air, produces unusual noises, or causes a musty odor, it’s a sign the system needs service. These symptoms may indicate a refrigerant leak, compressor failure, or electrical issue. Addressing the problem early can save you from higher repair costs and discomfort during long hauls.
