Service Intervals

Vehicles used in normal service do not require regularly scheduled maintenance. Fluid level should be checked whenever underhood maintenance is performed, or if leakage is detected.

On vehicles used for fleet service or those operated under severe conditions (such as police, taxi, or towing), regular transmission fluid changes are required. Drain and refill transmission every 22 months or 22,5000 miles.

If vehicles used for off-highway operation, check fluid level every 1000 miles. If operated in water, check fluid level and condition daily. Drain and refill if necessary.
