Thank you for using just answer.
Installing the different transmission in your car would be no easy swap, the transmission layout in your car is actually not too difficult to repair if you are simply having a few issues such as worn synchronizers that make shifting difficult, I have rebuilt several of these transmissions and it can be done in under a day and usually under $1,000. The transmission in your car will be hard to find used as most of these are either still on the road or the used ones are already trashed, a new one can be purchased for about $2,200 if you prefer new but I would highly recommend you consider having this one rebuilt. The 6 speed in the GT-s is no more reliable then the one in your car.
