If $X \leq_T Y + 0'$ does there always exist $Z \leq_T Y$, $Z \leq_T X$ with $X \leq_T Z'$.

Obviously, we can find $Z \leq Y$ where the $y$-th column of $Z$ has a limit equal to $X(y)$.  Just let $<y, s>$ be given by the computation of $X$ from $0'_s + Y$.  However, I realized I wasn't sure if it was possible for it to be the case that any such approximation includes information that $X$ can't compute.  Probably, I'm overlooking something obvious.

If not, is there a natural class of $X$ for which this property is guaranteed?
