I don't have a reader which can report the tranny temp. I believe if the tranny fluid is the wrong temperature some wont come out and I could be overfilling it.
you cant realistically overfill it unless you drive it hard during the new oil warm up procedure, it will come back out once its full. It is getting the new fluid to the proper temperature that is the tricky part, not draining. You have to fill as much as you can, plug it, start the car, put transmission in drive and warm up the fluid, plus run through the gears, and fill it while the car is still running (at least, thats what worked for me) If you dont get it up to temperature you wont be able to add enough. Not hard to do though, there are a handful of write-ups around the net and I havent seen any horror stories of a botched job yet.
