Why Engine & Transmission Health Matters
Your engine generates power while your transmission transfers that power to the wheels. When either system begins to fail, you may experience:
Rough idling
Delayed acceleration
Slipping gears
Grinding or knocking noises
Burning smells
Check engine light illumination
Poor fuel efficiency
Ignoring these warning signs can lead to more severe damage and costly repairs. Early diagnosis is key to protecting your vehicle and avoiding breakdowns. At Buster’s Service Center, we focus on identifying the root cause of the issue rather than applying temporary fixes.
