UPDATE: Found some time today to "change" the PTU fluid. Got the plug out no problem. Pretty big glob of crud on the plug. Sticky and smelly as everyone else has found. Attempted to remove fluid using a Mighty Mini Vac and i couldn't get any fluid out at all. Tried maneuvering the tube around to different angles, still nothing. So, logically, I thought, I will just add some fluid, drive it around, and change it all out again. Well, I added quite a bit of fluid, maybe 8-10 ounces before it was full. I'm guessing the vent allowed most of the fluid to "vent" out of the top. Drove the car a few times last night picking up the kids from various places. I will change out the fluid again this weekend.
