Oh-oh.

check the oil level first. Do this CORRECTLY - get the dipstick for the transmission. It`s cheap.
The transmission will not work correctly with either too much or not enough fluid in it. I have described the procedure (in english) here, including the part number for the dipstick.

What you feel as "five speeds" is the torque converter lockout being switched on and off. Normally, this should be a smooth process you hardly notice. If this is jerky and hard, something`s not OK.

I figure that you do not have an owner`s manual. I have made a .pdf version of the german version (8,6MB) you can download here.
