So I have been looking and cant seem to find where you fill the transmission (manual of course) with oil. and I have not looked at the diff, but might as well ask where you fill and empty that as well.

There's 1/2" size square plug in both ,, I believe the trans plug is on the Drivers side ,, but really you'll see it when your under the car.. The diff's in the rear of it for filling and theres a drain plug on the bottom

The trans fill plug is about halfway up on the passenger side I believe...I changed mine a couple of months ago and I think I remember that. Like he said though it's easy to find.

yeah its on the passenger side. the drain in the transmission also has a magnet on it to collect metal shavings, make sure theres nothing out of the ordinary or excessive shavings. pretty sure the diff fill it on the driver side, its pretty tight but not very hard to get at with a 1/2" breaker bar
