MTX Cocktail:
I just picked up a bottle of FM today, still have to get some Synthetic ATF. Going to go with the Mobil 1, I think.

I was wondering: On the FAQ trans. change method, it is stated that on the last bottle, "have the fill plug handy since it will come back out the fill hole rather quickly once full."

Can you overfill / underfill the transmission? What happens if I get too much in? Too little in? Can I damage the tranny if too much fluid is in there?

And once again, for those of you who did this at home, how long did the whole process take? Any difficulties?

Thanks.
