I drove my 1995 Saturn sl2 until it had 263,000 miles on it. At that time, the transmission started to slip. I then gave it to a friend, to buy a newer Saturn sl1.
I am prettysure you can change the motor as long as the body structure is the same and you have skill in this sort of thing.
Are you asking how to??
