The people who use Team Valley come from Gateshead and the places to the South like Birtley etc.
I don't think there should be a bus service but those people are more likely to go to Kingston Park because of the flagship Tesco there and large M&S food opposite.
Living in the Derwent Valley, I quite often pop over to Kingston Park rather than Team Valley. By car, it's just as easy to get to, and unless I want to buy a kitchen from Wren, a bed from Dreams, or a sofa from SCS, (the latter two are also present at Metrocentre) it pretty much has the same shops, with the added bonus of Aldi and Food Warehouse too.
