no you should flush that thing it will last longer at least 6 months

Might be even longer if you get the transmission filter replaced as well. Do you have maintenance records of this vehicle?

Old school thinking was that fresh oil would wash out the gunk that was holding the trans together. It's not true. Don't just change the fluid, get it flushed, and change the filter. If the trans is worn, add a quart of transmedic or similar high-mileage treatment.
