Well Chris, they may label the unit as sealed and not needing servicing, but that makes just about any real mechanic cringe inside. OK, lets pretend that it does not need traditional servicing like other transmissions. It still must have the correct fluid level at the very least, no automatic transmission can function without fluid no matter how healthy or new it may be. There will be provisions for checking the level of the non serviceable transmission and it almost surely will involve tools and a jack and jack stands to perform this check yourself. Sometimes you get lucky and there is a drain bolt, sometimes not…but there will be some provision to fill the unit, and this will likely be how you check to see if it is full as well. I’m sure there is information on this vehicles transmission on the Net
At the very least you must have the fluid level looked into and determined to be properly topped up. The color and smell of this fluid provides clues as well so if you are doing this, keep that in mind. Once you are sure about the level, you can then test and see what you get.
