Fluid and filter change on 4r70w tranny
I am hoping to change the filter on my 4r70w tranny this weekend and I was wondering how many quarts it will take to top it back up and exactly which type of mercon fluid to put in it? Also, while I'm here, the tranny has 135,000 miles on it....how long do these trannys usually last? Are they dependable?

I agree with FlaresideThunder about draining the torque converter. I have done that before, but since I service mine every year, all I do is drop the pan and change the filter and add the 4-5 quarts. If you want to access the torque converter plug, you'll have to remove that little black rubber on the bottom of the bell housing. Then you'll have to bump the starter a few times until you can see the drain plug. If you do this, you will need a few more quarts.
