Try R&Ring your existing fluid with Synthetic ATF.
Easy way to do this is to remove as much of the old fluid as possible (I used a turkey baster), then top up with Synthetic ATF. With the engine on, turn your steering lock to lock and hold it there a couple of times then remove as much as you can then replace with synthetic. Do this about 3 times and you will then have the bulk of your fluid as synthetic. This is especially useful if you live in climates with extremes (cold and/or hot).
