2004 Toyota Sienna
Several dealers are making different recommendations, and I don't know which one to follow. Would you help?
Some dealers are recommending that I do full automatic transmission fluid flush because it ensures 100% fluid will be exchanged. Some dealers are against this since high pressure can damage seals & gaskets.
Instead, they are recommending that I do transmission fluid drainage, and do this every 15,000 miles. But, the other dealers are against it since it will exchange only 20% of the fluid.
Some dealers are recommending that you need to do this only every 90,000 mile interval.
I couldn't find any recommendation in Toyota's Owner's Manual regarding transmission fluid. What do I do?
have the same problem?
