Can't downshift while warming up
Heya
I got a 2015 FR-S a couple of months back, and I live in Eastern Canada where it's getting rather chilly as winter is coming quick. I go to work around 8am every morning, and I've noticed a few transmission quirks(I Hope) on the drive in to the city. I can shift into Reverse, and shift up normally, but I cannot down shift at all while the car is still warming up? In the morning I generally let the car idle for a minute or two before I set off, but once I hit third, it's absolutely impossible to downshift into second unless I come to a complete stop. Is this a normal issue while the transmission is warming up, or is this something I should be taking it to the dealer about? After about 5-6 minutes of driving everything goes back to normal, and it doesn't seem to happen in the evening (yet anyway, it's still warmish for now) |

It's normal. Try double clutching and replacing OEM fluid, I use Motul 300. Also make sure you are rev matching on down shifts.

Yeah I read about changing the transmission/dif fluid right after I got it, guess I should stop procrastinating on that like an idiot. Good to know it's not a serious issue

Great time to learn to double-clutch. With OEM gear oil, the tranny will break in nicely at around 8000-10000 Km. ...really nicely. I love mine.

I second the above posts (I live in Denver, CO) and the only things that can alleviate it are double clutching and quicker shifting (not more forceful). I'm now past 15k miles, and the tranny continues to improve little by little as the miles rack up.

I've had to experience this more and more now that I've moved to Atlanta from Central Florida. Does anyone know if there is any harm in shifting through all the gears (with the clutch in the entire time of course) after the car has initially warmed up? Would this help distribute some of the warm gear fluids before setting off on your drive?

Sounds normal for me. As long as you don't feel any grinding, you're fine. I think stock fluid gets pretty thick when it's cold, so I ended up replacing with thinner oil and shifting improved.

I don't think it will help because the gears aren't rotating unless you're moving. Remember, the clutch is on the front end of the transmission, not the back end. The output shaft (and all the gears) are sitting still when you're stopped. They rotate with the rear wheels, the only disconnect is neutral or the clutch. The input shaft will move a little bit when you row through the gears, be it won't be spinning either unless you engage the clutch. If you're in neutral with the clutch engaged, then the input shaft and intermediate shaft are spinning freely inside the gears, but no gears are selected so none are moving (if they were, then the rear wheels would be moving as well).

3-2 shift will always feel a bit stiffer due to triple-coned syncros, but it gets better after 10k miles.
Warmup from cold start really helps, 5-10 minutes idling and then a quick loop around the parking lot or a slow roll down the road helps out, really only necessary on freezing days, otherwise I can usually take right off after initial warm up. |

Your clutch adjustment might be just off enough to barely hang up when cold, this can then go away once things warm up and expand.
My trans after adjusting tighter (clutch starts being actuated earlier when you push the pedal) made everything better. |
