Transmission fluid lubricates, cools, and protects your transmission's internal parts. It also powers hydraulic systems that shift gears smoothly. Over time, it breaks down and can become contaminated with debris.

Service intervals vary by vehicle and transmission type-some need fluid changes every 30,000-60,000 miles, while others may go longer. Check your owner's manual for your specific schedule. Neglecting transmission fluid can lead to shifting problems or damage. Bob Allen's Service team knows the right intervals and fluid types for your vehicle and can help keep your transmission running strong. Call (877) 331-4442 to schedule a transmission fluid check or service.
