What do I need to look out for when I'm looking for a engine and auto transaxle to replace the one in my '95 SW2. Will any year S series DOHC work if I insure that the proper sensors and engine controls ( EGR, throttle position etc.) are installed for the 95's OBD I computer? I imagine that my choices for a transaxle are more limited unless I convert to a 5 speed. Any insights, info and comments will be much appreciated.
