Why not just try it and note what you are doing?

So noting stream might be something like:

"Aversion to pure noting. Interest in 3 speed practice. Trying self-enquiry. Asking 'who am I?' No answer. Loss of interest in self-enquiry. Trying do nothing. Doing nothing. Good. Oh shit just came back from thoughts about ex. Doing nothing is harder than it looks. Returning to pure noting. Etc."

In my experience the Self inquiry arose on its own when Mind was in EQ Nana. It would come n form
of "who is seeing? Who is hearing? Who is thinking? Who is sensing?" 
I think it's ok to just ask this question even before the EQ Nana but for me it arose naturally in the EQ. 

The Do Nothing part is "backwards riding the Ox back home" were there is utter trust in the Ox knowing where to go what to do. One gets out of the way of This unfolding.
This is a tricky one pre-Path in my view but I could be wrong. 

I would not lose the Noting Monentum you clearly have. It's ok to ask "who is seeing, hearing, sensing, thinking" every once in a while but if you ask me I would just go Noting until deep into EQ before dwelling deeper into 2nd and even 3rd Gear. 

What you might need is some more concentration maybe and open eye Kasina while Freestyle Noting can offer this. You can even do Noting Aloud while doing Fire Kasina. I tried it and it also works. 

This is just my view mate and I hope not to confuse you more with it  

May you practice well.

Claim your practice it's yours! Test and see what it does. I would give it at least a few months.  All practice needs to build a momentum. So does concentration practice. Stuff takes time to reach a certain inertia. Patience. It's like fishing. You have no idea if a fish will snatch the bait You throw it into the water and wait. So here light up that Kasina and wait and see what pops up. 

Best wishes! 

Doesn't transmission part in three speed transmission need teacher? Presumably inventor of the "technique"?

Just thinking out loud...

Inventor??? LOL It's Kenneth Folk man He simply triangulated between Noting (1st), Self inquiry (2nd) and (his take on) Mahamudra (3rd gear). No magic here mate. Actually anyone with magic stuff ought to run away from Kenneth just kidding , he is a lovely guy.

He took readily available components, put them in some order with some logic, created name and even proper documentation... I would say it definitely his invention and anyone hearing "Three speed transmission" will think: Kenneth


Wasn't he supposed to be doomed to special Buddhist hell or something?

Nah. He is one of those who will simply expire after death.
