in a Vibe, transaxle and transmission mean the same thing. There are differences between the real meanings of the terms, a transaxle contains a transmission and a differential, but that's for the purists, it's a transaxle, but I still call it a transmission. If you had that fluid changed recently, then that part is done.For the differential and transfer case, the info is in the owner's manual, which is available for download from
