I'm somewhat lost. 

1. Are you trying to lay TMS tiles over Google Maps?
2. Are your TMS tiles in the Spherical Mercator projection? What did
   you use to generate them?
3. Do you have the sphericalMercator option set to true on your 
   Google layer?

Might be helpful.

Might be as well.

If you are trying to overlay TMS tiles which only cover a small part of
the world on top of Google Maps, this does not yet work.
