The PVG connection is too tight. You only have 1:15 and the minimum connection for PVG is about two hours. You can always book it as separate tickets yourself, but you take the risk of misconnect.

There is a bus that will take you to SHA. They say that it takes about 1.5 hours, but the last time I took it in the opposite direction (SHA-PVG), it was just over an hour. So a 6:45 PM departure seems doable.
