I am the original owner of a 2008 Toyota Sienna LE with 105,500 miles. Last time I did a transmission fluid drain and fill was at 43,500 miles. With all the pro and con information out there about doing a transmission fluid service, out there, should I do another transmission fluid drain and fill even though this is an older higher mileage vehicle? There are no transmission problems thank goodness. The vehicle has been driven normally and has been well maintained. Thank you in advance.
