Over time, wear and tear can affect both your engine and transmission. Problems often start small and grow if left untreated. Common causes of failure include:

Engine Problems:

• Worn spark plugs or ignition coils

• Oil leaks from gaskets or valve covers

• Timing chain or belt issues

• Faulty sensors or electrical problems

Transmission Problems:

• Low or contaminated transmission fluid

We take the time to diagnose the source of the problem so that you get repairs that fix it the first time.
