• Fluid exchange using the manufacturer's specified fluid
• Scan for stored transmission fault codes

Most manufacturers publish normal and severe-use schedules, and towing, heat, and stop-and-go driving can place a vehicle in severe use. Fluid condition can be inspected between scheduled points.

• Manual transmission fluid: replace every 40,000 miles
• Fluid condition can be checked when symptoms appear
