Complicated. There are two designs of TC front for Suzuki Vitara and GV. They look very different. One type is used on AT, the other on MT, except with the 2 litre, where the AT type seems to be used on the MT. For the XL-7, the MT type was used on the MT up to 2002, then it switched to the AT type.
Best thing would be to get transmission and TC from the same donor.
No info about Trackers, but you'd expect them to be the same as the Vitaras.
