3rd gear inconsistent shifting

I Highly doubt that our BRZ transmissions are designed for drop-clutching.

The car is actually designed for drop clutch oversteer which is very hard on a transmission. The technique to induce drift is to punch the clutch rapidly in and out while cranking on some steering lock...don't try this in winter!

The shift lever is pretty short and short throw also, nice but increases shift effort.

Patience shall be rewarded.

The shift quality of my transmission is improving rapidly at only 2,400 miles (4,000 km).

I have been noticing a lot of missed shifts in my car.
It is used and had 9k miles on it when I got it, 11k now.
I have driven all kinds of MTs in my life and have had more missed shifts in this car than almost all my other cars combined.
I have NOT changed the fluid yet, but plan to soon.

Just the other day I had a particularly nasty one.
I was driving casually, shifted 2nd to 3rd and ground it so hard it scared me (like it bit me). I immediately took my hand off the shifter and pushed in the clutch, and when I looked down I saw the shift lever complete the move into third by itself when I pressed the clutch.
I let out the clutch (again without touching the shiter) and it was in third.
So that means that my "missed shift" got the tranny part way into third and my, essentially, double clutch completed the shift.

Seems that the tranny can get part way into third and get "caught".

When I got out of the car I could smell the burnt gears, so I was NOT pleased.
Anyone else noticed any odd behavior when they "miss a shift"?

That happened to me a handful of times on 3000miles of driving mine. I've missed a shift a few times in my always_manual_gearbox_driving career - 17 years, but this is definitely more often. I changed my oil to a thinner one (Redline MTL) a few weeks ago and the shift improved a lot. But today I did it again. So yes, sometimes it seems to trick me that I got a gear and I release the clutch *crunch* - oops apparently I haven't. Our gearboxes have triple synchromeshes on the first three gears I heard, these can take some time to break-in properly. So for now, I just have to readjust and take greater care shifting.

On the bright side, I like how with this car it matters how you drive because it will show right away, there's no fluffy mistake forgiving vagueness in any of the controls...
