Many car manufacturers promote the idea of “lifetime” transmission fluid, suggesting that it never needs to be changed. However, experts and the National Highway Traffic Safety Administration (NHTSA) warn that this can lead to costly repairs. Over time, transmission fluid degrades and loses its effectiveness, which can result in transmission failure.

Manufacturer Guidelines

Major automakers like Ford, GM, and Honda recommend regular transmission fluid changes, typically every 30,000 to 60,000 miles, depending on the model and driving conditions. Ignoring these guidelines can lead to severe engine damage, decreased performance, and increased repair costs.

Urgent Reminder

Car owners should not rely solely on “lifetime” claims. Regular maintenance is crucial for vehicle longevity. Check your owner’s manual for specific recommendations and schedule a fluid change to avoid potential breakdowns.
