If the cluster is from a V6 it will function but the tach probably won't read at the proper RPM's. There is a resistor and diode on the back that(I think)needs to be swapped out to a different value for the tach to read the signal right. Transmission doesn't seem to matter from what I've gathered and even the year is variable. My cluster is from a 99 Mystique ATX...I got a 96 Mystique cluster for a guy in OK with a 96 or 97 with manual, so far its working good.
