2004 Toyota Sienna 6 cyl Front Wheel Drive Automatic

My sienna has 83,000 miles and the transmission fluid has not been changed. Is it ok to flush the trany fluid on this vehicle or should it just be drained and refilled. If so, how much fluid does it take. The owners manual doesn't give any information on this.

Hi agrtech,

Thank you for the donation.

Trans flushing is not recommended and some manufacturers strongly advise against it.

Draining and refilling are the standard recommended procedure. For your vehicle the drain and refill capacity is 3.70 qts ( 3.5 L) and fluid should be Toyota Genuine ATF type T IV.
