vin#MA23B1YP304321 AND MA23B8YP217094 ARE THE TRANMISSIONS FOR THESE CARS INTER-CHANGEABLE

I don't have acces to my computer right know but you can check the tranny code to check. It is a 3 letter code on the transmission serial plate or ussually in the trunk on a paper that has the engine and transmission code. With this code you can check if they are swappable.
