Transmission fluid lubricates, cools, and protects your transmission's moving parts. Clean fluid shifts smoothly; dirty or low fluid can cause slipping, hard shifts, overheating, and costly transmission damage.

Most modern transmissions need a fluid check or service every 30,000-60,000 miles, though intervals vary by vehicle. Synthetic transmission fluids last longer than conventional. Regular maintenance prevents expensive repairs down the road.

Bareford GMC Service includes transmission fluid checks in many maintenance packages and can recommend a full service if needed. Call (804) 445-2810 to find out what your GMC requires and schedule a fluid check at your next visit.
