It should use Mercon IV if it is an auto make sure u get the correct fluid not sure about the 5 speed but I think it is the same stuff. There should be a logo on the
trans dipstick or tell u in the owners book. But filling it make sure the mark the dipstick level is correct for cold or hot, u can over fill slightly but not a lot maybe a half a qt is ok; but if it is a 5 speed there is a plug in the side of the
trans about half the way up on the passenger side, almost centered if like the older ones, u just fill it until the fluid flows out of the hole.
