California transfer to a family member is title transfer fee ONLY. So that part is easy. Sign the title over to Sally and sign a paper indicating the transfer. You don't need to go in, but I would suggest that Sally take care of that while you are still here. Title transfers can be done at any AAA office if you are a member. Otherwise there are other insurance companies that also offer that service.

California is also a community property state so pretty much everything you own is already Sally's if it was bought after you were married.
