I don’t know if the above translation is correct and. In fact, I am sure there is something wrong with it. I don’t know if the above translation is correct. In fact, I am sure there is something wrong with it.

You can't link with "and" because there is slight contrast between the two clauses. You said "I don't know if the above translation is correct" but if you say "I am sure there is something wrong with it", you *do* know that the translation is *not* correct. This means you have to say something like "In fact" to show that actually, after thinking about it more, you changed your mind.
