At Access Transmission in San Antonio, we understand how critical your vehicle’s transmission system is to its performance and longevity.

That’s exactly what we deliver—precision diagnostics, expert repairs, and unbeatable customer care, all from a locally trusted team with decades of experience.

Why Transmission Repair Should Never Be Delayed
Ignoring a failing transmission can lead to catastrophic damage and extremely costly repairs. Whether you drive a car, truck, or SUV, your transmission is responsible for transferring power from the engine to the wheels efficiently. Early signs of trouble include:

  • Slipping gears
  • Delayed acceleration
  • Burning smells
  • Leaking fluid
  • Check engine light

Our certified technicians in San Antonio specialize in catching these issues early before they become major expenses. We don’t guess—we diagnose and fix it right the first time.

Comprehensive Transmission Diagnostics and Service
At Access Transmission, diagnostics are never rushed. We utilize the latest in diagnostic equipment to identify the exact source of the issue, whether it’s mechanical, hydraulic, or electronic. We provide a detailed inspection that includes:

  • Transmission fluid check
  • Road test
  • Lift inspection
  • Computer diagnostics
  • Leak detection

Once the issue is identified, we provide a transparent and fair estimate so you understand exactly what’s needed and why.

Automatic Transmission Repair & Rebuild Services
Automatic transmissions are complex systems that require an experienced, specialized team. Whether your transmission needs a fluid flush, clutch replacement, solenoid repair, or a complete rebuild, we have the tools, parts, and expertise to get it done quickly and correctly. We work on all major makes and models including:
