* Year and Model: Different years and models of Mustang may have different recommendations. Older Mustangs may have less sophisticated transmissions requiring more frequent changes. Newer Mustangs with advanced transmissions might have longer recommended intervals.
* Transmission Type: Whether it's an automatic or manual transmission significantly impacts the service schedule. Manual transmissions generally require less frequent fluid changes than automatics. Within automatic transmissions, different types (e.g., traditional automatic, dual-clutch) have varying needs.
* Driving Conditions: Severe driving conditions (towing, frequent stop-and-go traffic, extreme temperatures) will necessitate more frequent fluid changes. Regular highway driving tends to be gentler on the transmission.
* Owner's Manual: The most definitive answer is always found in your Mustang's owner's manual. This document will specify the recommended service interval for your specific vehicle.
In short, there's no single answer. To know how often *your* Mustang's transmission fluid should be changed, consult your owner's manual. Ignoring this advice could lead to premature transmission wear and expensive repairs. If you can't locate your manual, you can often find a digital copy on the Ford website by entering your VIN.
