Vibration is likely universal joints and possibly transmission mount.

Not sure about your transmission, but my 2.4 - 5-speed required about 2 quarts. The manual should have that info under the specs section.

Good to see you again, Tiny.

I filled my transmission fluid from the shifter, because at the time, it was removed. Leaving the fill plug out, I waited until it overflowed. I later replaced the shifter. Otherwise, you need a small hand-pump to get the gear oil up there. Whatta pain, but oh-so-worth-it. Might as well get another couple quarts and treat your differential, too.

And remember: donuts make ANY occassion that much better. Donuts: they're not just for all the time, anymore.
