Condition-Based Service (CBS) tells you exactly when service is due. Transmission fluid was labeled 'lifetime' but many owners service at 60K-100K.

"Severe service" conditions (heavy towing, extreme temps, city stop-and-go) typically halve these intervals. Always consult your vehicle's owner's manual for the authoritative schedule.
