Need working used engine and transmission for 2.0 GL

What is your question?

I have just been told my Passat is a sinking ship and will soon need a new engine and a/t. I have over $ 5000 in it and before I write it off, I would consider replacing the worn out engine and a/t. My other avenue of escape is to try and sell it for parts as the interior and body panels are in excellent condition. I need suggestions. Thank you.
