Layover 2 hours in Shanghai

Hello,

I purchased our ticket with Delta from MCO-LAX-PVG-KUL but from PVG to KUL with SH Airlines. I have only 2 hours layover change gate form terminal 1 to terminal 1. Do We have enough time? I have been asking Delta about this layover but they mentioned I don't checked my luggage, thru security, passport control. Delta will print our boarding pass all way to Kuala Lumpur also We reserved our seat. Thank you
