What's blocking me when I downshift from 6th to 4th

No, I have never turned on the feature that shows what gear the MT is in. I just seem to know what gear it is in by the sound of the engine and speed of the car.

Except, occasionally, when I try to take off in 3rd gear, thinking I'm in 1st gear. My FR-S don't like to do that .....

That "best gas mileage" upshift indicator is a handy reminder to me that it's ok to short shift. Also, all the guys driving automatics are hovering around the same engine RPM.

My opinion on the subject of lugging has evolved since owning this new high-tech machine. I still sweat low oil pressure but have come around to the idea of staying within the lower torque bump if I'm just cruising in traffic.

I've tried double clutching, but I still feel the resistance going into 4th. I also rev match and the ride itself is smooth and not jerky.

The weird thing is that when I shift from 5th to 3rd this doesn't happen.

Does anyone know whats going on? Should I not continue to put the car into a gear if I feel something blocking?

I go from 6 to 4 regularly. Never had an issue

I'll stick to the simple things for now, but for an effective double clutch, do I have blip the throttle with the clutch completely released?

I replied to your original post but I'll comment on double clutching here too. I've never once double clutched and I skip gears/gates all the time (just be extra careful not to shift into 1 or 2 at 60mphor you'll blow your motor). As for throttle blip... Clutch in, then blip, then clutch out. When you down shift the motor will soon faster (higher RPM) so you want to blip the throttle to get to that RPM before clutch out. I always just slipped the clutch and it was meh. Started blipping, huge improvement in driving feel

I strongly advise against skipping gates. You may not feel it for tens of thousands of miles but the damage is happening.

Minor correction mostly to the confusing phrasing that get's used all the time on this.
Clutch in. Shift. Blip while letting clutch back out again. The blip should be happening at the same time as the clutch petal is moving not as a separate action.

Yes Tcoats description is better

I read the "steps" all the time and it always sounds like these are separate movements. In reality a shift is all one action I shall call that action: startmovingshiftleverwhilepushinginclutchthenoncei ngearstartlettingoutclutchwhileblippinggas.

Even double clutching? I skip 6->4 on occasion now on the freeway and double clutching results in the shift-lever-action being as smooth as a 6->5th.

On a side note, if I don't double clutch from from 1->2 for the first couple of shifts, I feel an extra click/crunch . Seems like it's normal for this car(lots of related threads) but I don't like the feeling. I saw somewhere that double clutching on up shifts might be bad. Does anyone know why? Or is it just more prone to error

Thank you. Agree.

No, you're nailing it just right. If you know how to do it then yeah, you understand the reason for the advice and you are compensating accordingly. ...I hope. Except for a missed shift, there's no reason to double clutch an upshift.

My go-to for passing is third. Sometimes I rake through, sometimes I double clutch.

With respect to the cold 1>2 shift, because all the gear pairs are swimming in thick molasses fluid, the mid and input shafts come to a screeching halt as soon as first is disengaged. With the clutch disengaged and transmission in neutral, the only parts that remain spinning are the third and fourth gear pairs. The 1-2 syncros are at a mechanical disadvantage so the trick is to not pause in neutral at all. A quick flick out of first with immediate fingertip pressure into second usually does the trick.

If not quick enough then I also double clutch to spool up the input side for a second try. I never lean into the gear selector.

I marked this up for myself. Don't be misled by the gear underneath the 5. That's actually the gear at the end of the input shaft which drives the mid shaft. Fifth gear just couples the output shaft to the input shaft.

Rake as in clutch in, 6>5>4 to "spread the load"?

This makes a lot of sense. I was testing some things out to avoid the crunch and tried someone's suggestion of centering the shift knob for a 1/2 second on a cold 1>2 shift. This resulted in 2nd being blocked entirely and having to go straight to 3rd.

Also, even with the crunch 1>2 shifts without any resistance, just not as pleasant.

Thanks for the technical response, much appreciated.
