How do I properly check the transmission fluid?
Since I just replaced the Front CV axle on my 2001 Rio a few days ago I decided to check the transmission fluid today to see if I put enough in when I finished the install. The car had been sitting in my garage for the past almost 40 hours, so it's definitely cool. I pulled the transmission dipstick and noticed there were two sets of fill marks, one with a temp around 25*C and another around 65*C. the fluid was at the full level for the 65*C mark. Not expecting that, I searched through my owners manual and found section 7-23 that says the transmission fluid should be checked after 30 minutes of driving. Section 7-24 says if you have to check it cold, let it idle for two minutes, then run it through all the gears and check the fluid level (while still idling). So, I let it idle for two minutes, ran it through the gears, pulled the dipstick, wiped it clean, and re-inserted it. When I pulled it again it came back bone dry. Now I'm really confused. At first it looked like it was probably too full because it was cold but was measuring at the full hot mark, and now it is idling and measuring as if there were absolutely no fluid in there. Can someone please tell me what I'm doing wrong?
I debated driving it up the highway for 30 minutes and then checking it "properly," but if it's really totally empty I don't know if driving it is such a good idea. I also thought about just adding more fluid, but if it's actually full I don't want to overfill it.
Thanks in advance!
