Hi, I'm interested in replacing the fluid in my Frontier's automatic.
1) I've looked at the numbers and see that 3 drains of 3 qts each will replace about 2/3's of the fluid.
2) I'm also considering the method whereby I utilize the transmission's pump to remove one qt at a time from the outlet line at the cooler.
This is my question:
I have not been able to determine from the posts that I've read if method 2 mixes any of the new fluid being added during discharge or if it discharges fluid which is completely unmixed with new fluid being added during the operation. Is there a continuous path from the torque converter to the point of discharge?
Also, does it matter that the inlet side (disconnected from the cooler) is open to the atmosphere while discharging old fluid? Will air be sucked into this line and if so, does it matter?
is there anyone knowledgeable about the auto's operation that can answer this question?
thanks
