Only the 5-speeds. You can't swap automatics without running into problems, and you can't swap an automatic for a 5-speed without modifying (and it will still throw an engine code afterward). A 1992 Corsica had a 3T40 automatic, and the 1995 Beretta had a 4T60E automatic. Your best bet is to swap in another 4T60E. It came in a lot of GM vehicles. Go to car-part.com and enter "1995 Chevy Beretta automatic transmission" in the search for a list compatible transmissions and prices in your area.
