comment Is there a codifferential for a covariant exterior derivative?
mathoverflow.net/questions/97061/… seems to answer the question but it does not explain how to extend Hodge star to bundle valued differential forms.

comment Can a bilinear map on smooth functions induce a bilinear map on tensor fields in this way?
to clarify terminology $(\alpha f + \beta g,h) = \alpha (f,h) + \beta (g,h)$ is linear over $\mathbb R$ if $\alpha, \beta \in \mathbb R$ (this one I meant) and over $C^\infty(M)$ if $\alpha, \beta \in C^\infty(M)$, right?

Thank you. Right now even flat case would be nice. Do you have an explicit expression for $\delta^\nabla$? (it would probably require an extension of Hodge star operator).
