If it's ATF then you need to take off the sump guard, clean off all the area and start checking where the leak is coming from. It might be coming from the torque converter in which case it's transmission out or it could be coming from a faulty switch housing, can't say. The 2.2 engine is known for leaks around the sump and tiiming cover also been known to leak from the oil cooler pipes. Probably be better getting it on a ramp.
The self-levelling rear shock absorbers have fluid in them, same as the other type and they will leak externally if the seals are gone. I don't know how bad the leakge looks when they go, never had any trouble wiht mine.
