Just turned 45,000 miles, so the car went to a trans shop in Hackettstown. They changed the trans filter, and did a full flush ($119 for flush, $139 filter and flush). They use Valvoline DEXRON®-VI ATF, which is a synthetic oil. I checked out the Valvoline website, and their Dexron-VI is good for our transmissions.

Went a little past the recommended service interval, but its nice to know it is done. Better late then never! The shop also asks for you to come back in a few days so they can check for leaks and make sure everything is sealed up tight. That's a nice touch from a garage. And they had the best price for a trans flush using synthetic fluid of any shop around (that I could find).

While on the Valvoline website, I read where adding fresh oil to old dirty oil will cause sludge to build up faster than old oil alone, so they make an additive for service centers to add when doing the partial change when just dropping the pan and changing the filter. Thought that was interesting to know.
