Bring your service history and describe whether the problem happens cold, warm, under load or at a particular speed. Diagnosis may involve a road test when appropriate, electronic fault information, fluid and leak checks, and inspection of related controls or drivetrain components. A shift complaint does not automatically mean the entire transmission needs replacement.
After testing, we can discuss the work indicated, parts choices, estimated cost and applicable warranty details. A fluid service is maintenance; it cannot restore worn internal parts.
