Ya gotta get the repair manual if ya wanna work on your VX.
Also, everyone should be changing their PS fliud on a regular basis to avoid costly repairs. Many shops will do a PS fluid flush, or ya could do that on your own. A real simple easy way to freshen the fluid is to just remove it with a turkey baster thing. Remove the reservoir lid, pull up on the baffle to remove it, remove fluid, refill with tranny fluid, replace lid, start engine and turn the wheel back and forth, shut off and repeat about five times, replace baffle and lid, drive happy.
I've done that a few times over the years. [fingerscrossed]My PS system still works great after 209K miles.[/fingerscrossed]
