Strange sound when shifting into first or second
 

Guys - Im new to driving manual transmission cars. I bought a brand new series blue BRZ 2015 (i put about 280miles already) and I'm learning to drive manual on it. I been noticing a strange sound/rattle when shifting into first or second gear. The sound goes away when i give it more throttle. Also, this only happens sometimes, i been noticing usually happens when I'm not engaging the catching point correctly (but I'm not sure as I'm new to driving manual)...

Should i be concern of that sound? could it be something wrong with the car? or maybe is just me not shifting correctly?

Any tips will be appreciated....

Short answer, its not a problem with the car neither you.

I'm not sure what that other guy is talking about...

You are likely hearing the clutch friction disc springs. These are tiny springs in the clutch that help absorb less than pleasant clutch engagements. The fact the clutch is still new and breaking in (i hope your taking it easy on the clutch!) may be amplifying the noise. Don't worry about it too much unless it gets worse, but hey that's what the warranty is for right? :w00t:

Thanks, yeah i been noticing that sound lately since im driving with my radio off to hear the sound of the engine that way it helps me when to shift...

I try to be gentle on the clutch but since i new driving manual, sometimes i feel like i dump the clutch too soon that the car jerks. Other than that is there any other tips to consider in order be gentel on the clutch?

Hey I have a 2015 aswell and have the same thing. For first gear if you hold the clutch in a little longer and then put it in gear you won't have any clunk. But second gear just clunky when it wants to

Same here. Have a 15' frs and when I'm shifting from 1st to 2nd from a complete stop, it feels like there's a clunk (idk how to describe it lol) in which I need more force from shifting to 2nd, compared to like 3rd or 4th..

so.... is this normal? I'm thinking maybe because it's new, so I'm hoping it might go away after putting a few thousand miles..

This is odd, normally you get the clunk when engaging 1st and a slight grind into 2nd, guess the new ones have a different story. Try one thing.. when going from 1st to 2nd go to neutral before 2nd.. So-> first.....nuetral...second..not in slow motion normal shifting speed. You should get nothing..if problem persists just drive the car normal, dont take it slow or easy if there's a problem taking it easy will just postpone it but not fix it, then take it in for a check up but give it a couple of weeks at least. Report back to know if anything changes.

I'll try that, that clunky feeling only happens on second gear (usually when im in traffic going like 10-15 mph). If i give it more throttle it goes away, im thinking its just because it's new so it might go away after a couple thousand miles... Other than that the car runs fine.

I currently have about 290 miles. I will report back with details when i hit at least 1k.

I'm trying to replicate this in my head.. "clunk feeling" is not sound. hmm.. One thing that many of us aren't used to with this car is that it makes noises, better yet you hear them, due to the lack of insulation and sound deadning material it has, hence its super light weight :). So just ride it out and let us know.

Yes, its hard to describe the feeling, it's something like it feels 'heavy' when doing light pulls in second gear.

Again, i never had a brand new car before, or never drove manual cars neither... I'll keep driving it, thanks though!

+1 to everyone else who suggested to just drive the damn thing. With little sound deadening and a super light, micro tolerance drivetrain... sounds will come at you from every direction. You'll go crazy if you're one of those "get paranoid at every sound" people. I'm one of them but after 10 years with high performance subarus and light toyos, have grown to accept the fact these guys just make lots of noise

Specific advice to your problem, let that input shaft slow down before you clunk it in. Pause for a few microseconds longer than normal from first to second if the speeds aren't just right, and voila, clunk/rattle/shitty feeling is gone. Also helps to flush tranny, but the stock fluid isn't that bad. Motul 300 will be worse cold, butter when to operating temp. Some have had success with pentosin as well. Just search for threads that suggest tranny fluid on here.

Also consider changing out rear shifter stay, mtec springs (will help with the gates and conversely your transitions between gears). TRD Quikshifter typically is more fun but will be harder to engage gears because of the design (own it, love it, don't deny its harder to shift if not using enough force). Can't comment about kartboy or other short/quick shifter setups, but people have had success with them as well :)

Not sure how the "thunk" became the focus here.
OP is it possible you are lugging the engine a bit in the lower gears? The fact that it goes away when you give more throttle means you may not be giving enough to start with.
Just food for thought.

Agree.. that rattle sound on first gear is gone when i give it more throttle when starting.. So for that problem, i think it just me learning how to drive it.

Now, there is a different question about when im in second gear (driving in traffic) the car feels 'heavy', like mentioned before it might because its new and im hoping it gets better with time.
