Transmission smoothing out over time - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Mine manual trans is still a little rough shifting. The warmer the engine the smoother it shifts. Waiting and hoping for the experience that many posters on this thread have achieved. I'm at 3,100 miles.

Mine became really smooth when I finished a 5hr autox session lol.

I used to have the difficult 2nd gear when cold requiring a doubleclutch until warm, but that went away at 2000mi, transmission is smooth in every gear now (at 5000mi stock fluids except oil)

I"m at 2500 miles and still tough to shift into 2nd in cold weather.
Must need better fluid

When completely cold in the morning, I make sure to be extremely gentle with the 1st-2nd gear change. If it won't go in easy, obviously don't force it! Just take another second and try again and it will go in. Once all warmed up, the gearbox is perfect.

I'm thinking about doing fresh fluids for the gearbox and diff though. My break-in peroid is over and it's a good idea to flush out any sort of metal shavings as with all new cars.

I have ground my gears a few more times than I am comfortable with.
Sometimes it just seems to require two clicks instead of just one.

I have not changed the stock MT fluid yet.

However, I was wondering if some of the problem might be the fault of the hydraulic clutch....
I dont recall ever having a hydraulic clutch, maybe it makes the cold shift problem worse.
Should I flush & replace the clutch MC with the good blue brake fluid when I do the redline MT fluid change?

That's what I did when I flushed the brakes. It made no difference. Tranny lube is what you'll notice.
