Frequently asked questions
Is transmission repair always expensive?+
Not always. Many transmission problems are a fluid, filter or solenoid issue rather than a full rebuild. We diagnose first and tell you the real cause and the price before any work starts.
How often should transmission fluid be serviced?+
It depends on your vehicle and driving. We check your fluid level and condition and tell you whether a service is due. Call with your year, make and model for the right interval.
