Keep Your Transmission Running Smoothly — Before It Becomes an Emergency

Transmission problems rarely appear overnight. They build over time — sluggish shifts, slipping gears, delayed engagement, or unusual noises are all early warning signs that your transmission needs attention. Catching these issues early can mean the difference between a service and a full replacement.

At Top Japanese Auto, we diagnose and service both automatic and manual transmissions in Japanese vehicles. We use the correct manufacturer-specified fluids and follow proper service procedures — something many shops overlook but that makes a significant difference in transmission longevity.

Services Included:

• Automatic transmission fluid service and flush
• Manual transmission fluid change
• Transmission diagnostic scanning and road testing
• Solenoid and sensor diagnostics
• Torque converter inspection
• Clutch inspection and replacement (manual)
• CVT fluid service (for applicable models)
• Drivetrain and axle inspection
  
  

A Note on CVT Transmissions: Many modern Japanese vehicles — including Nissan, Honda, Subaru, and Toyota models — use Continuously Variable Transmissions (CVTs). These require specific fluid types and service intervals that many shops ignore. We follow manufacturer-recommended CVT service procedures to protect your investment.
