Geotargeting content with Google Translate

Please, no theorists in this post. I only want advice from people who know the answer for a fact. Evidence preferred.

Let's say I had an MFA content site with 10,000 high quality indexed pages in English, and I wanted to create subdomains geotargeted to many different countries. If I simply translated all of the text on my English subdomain using Google translate into the appropriate language of the geotargeted subdomains, would this lead to any AUTOMATIC penalties from the Google crawler?

I realize a manual review will perhaps get the site deindexed since the translation will come out garbage, but my question is since it should come out as "technically" grammatically correct, even if it doesn't make sense, will Google's algorithms automatically detect anything amiss, or would Google consider these few thousand pages on the new geotargeted sites as being fantastic unique content?

My question is in regards to the automatic algorithms, not a manual review. If you don't know the answer, please increase your post count elsewhere.

I'll paypal $5 to the best answer.

Thanks.
