You definitely got screwed and the mechanics you went to are not worth a second glance.
What has engine misfiring got to do with the transmission? For vehicle diagnostics, engine performance trouble codes takes precedencse over all others and should be rectified first.
Have you checked the timing belt? It could have skipped a tooth.
Were the fuel pressure tested?
How about the spark plugs?
Get a compression test done as well.
