Problem syncing Gmail contacts on Android tablet

I have a Teac tablet (classic101) with Android 4.0. After signing in on Gmail and Drive and everything, my contacts won't show up anywhere. It doesn't show when I start writing an address in Gmail. It doesn't even show after I downloaded contacts+ (the contacts are empty). When I go to sync it, it suggests syncing email, calender and drive. But, there is no contacts! How do I sync my contacts so that they will appear on my Gmail on the tablet? I have over 2000 contacts on Gmail. It works fine on my phone, just not on the tablet.
