Common questions
Does every transmission problem mean a rebuild?

No. Fluid condition, sensors, wiring, controls and other components can cause transmission symptoms. The first step is identifying the actual problem.

Do you service differentials?

Yes. Differential fluid service, leak concerns, noise diagnosis and rebuild work are among the drivetrain services available.

Should I service transmission fluid before there is a problem?

Preventive service can help, but the correct interval and fluid depend on the vehicle. McKay's Garage can review the vehicle's condition and manufacturer guidance.
