What are the signs my engine needs repair or a tune-up?

Common symptoms include rough idling, decreased fuel efficiency, engine noise, warning lights, or hard starts. Schedule a diagnostic to prevent bigger issues.

How do I know if my transmission needs service or repair?

Look for slipping gears, delayed shifts, strange noises, or fluid leaks. Early transmission service can prevent costly overhauls.
