Most schools even laymen require transmission to continue foundational practices to the mahamudra. Don't be surprised if you are asked to start aspects over.
However. You have to work with your mind. If you are serious, you will take it serious, ask, seek, and guide yourself as much. Blessings/transmissions do not make you more wise. It holds a mirror up.
Even in Monastic settings, you do not always have personal individual teachings with a Guru, you spend more time in personal practice with other monks.
You will spend 90% of your time in early refuge doing prostrations, while meditating of the core teachings, holding that view. Don't power drive through it. My teacher once told me, if you want to power prostrate , which is exercise, go take a run down the hill side, this won't do anything for you. I already knew that myself. I simply ignored it.
Keep this in mind. All you need, you already have. No guru will give it to you, be give you a possible glimpse, and hold a mirror to you to point out aspects. The guide. WHiel taking former refuge, and the transmission is required, you will spend more time working with your own mind, then the guru.
