No, a 91 metro transmission will not fit in a 98. A 91 will fit any metro between 1988 - 1996 though. After 1996 a lot of Metro's became 4 Cylinder which made them different from the previous generation metros. It may fit if the engine sizes are correct (1.0 litre 3 cylinder to the same but do not mix and match).
