Engine/Transmission noise
 

Hi All:

I've started to notice that my FRS has a really sharp gear change in the morning from 1st to 2nd. It literally jolts the entire car. My car is an automatic and I've searched that this is normal on the manual version of the car.... Would that issue carry over to the automatic? Should I regard this as normal?

Another issue is...

Tonight I drove without music and with the fan off and I noticed that upon acceleration the car whines like it has a supercharger. It's pretty loud at about 3000 RPM. Can anyone confirm this is normal? Does your automatic FRS have this as well? I've tried searching "Scion FRS Whine Accelerating" "SCION FRS AUTOMATIC WHINE".

On my previous car, a whine noise ment a failing CVT... would a whine noise be normal in this case?

It sounds like this...but this is a manual transmission with some mods...but i'm not sure if the mods make that noise?

Thanks!

Car is a 2013 FRS, Stock, Automatic.

Based on your two issues, I'd guess there's an issue with your AT fluid pump. Too much pressure will cause a hard shift and I've heard many trannys start the whine when the pump bearing is going out on it

Sounds serious :(

Update:

This morning it's not as loud.. but the whine is still there.

it could be that you have low transmission oil, I would check that! because I had the same Problem, then I refilled it with new Oil and annoying V-teck Sound went away!

mine sometimes has a faint wine like that in the am when I first get into the car, but its gone after few min of driving

What did you change your ATF fluid with? Did you go with OEM Toyota fluid?

I have the auto frs. I get the whine sound when accelerating up to 2500rpm.. Only when the car is cold though.

I have the whine as well, same car (10 series, AT). I can clearly hear it when accelerating hard on the freeway onramp while in 2nd and 3rd gear.

I have noticeable jolts in the morning from 1st to 2nd too. Goes away after driving a bit, I think it's just cold tranny fluid. I sure hope it's not a failing AT fluid pump or low AT fluid, I mean, I barely have 2k miles on this thing!

I am having this exact problem. I first thought it was normal because it being AT. My truck made a similar sound. But once under load (cold or hot, hard or easy acceleration.) it makes a very noticeable whining sound and is driving me nuts! Has there been any resolve to this issue?

Could it possibly be the rear diff that you are hearing?

No it's somewhere up front. You can slightly hear it when the car is in park or neutral and you rev it past 2800rpm. I did this when the car was cold and warm. Still the same sound

I haven't looked into it as other people have stated it's normal. I haven't had a transmission failure yet soooo I guess it's good for now?

Well I have an appointment with toyota. Hopefully they say it's all good I'll keep very or here posted if they are still concerned

If it's an issue lmk... so I can go get something done LOL.

WE CANNN JOIN FORCESSSS LOLOL :D

Any updates?

mine makes that noise and has been making that noise from day 1, 50k miles and still running strong

Hey sorry for the late update...I haven't been to toyota yet. But I've been testing some thing's out and I may think it's something else and probably the culprit. I'm thinking it's the air conditioner clutch pulley. It doesn't do it in the morning because I drive the car to work super early. But it does after work and it's super hot out now(and yes canada does have summers and it isn't a frozen tundra) so when the AC pump is being worked a lot it starts making the sound. I don't know if people here have had any luck lately but that's my theory hopefully someone will figure it out

I have super hard shifts going up through any gear. Also used to have the whine but now it's more of a chugging sound

Bumping this because I finally took my car to the dealer for this noise.

Since we never came to the conclusion if this is considered normal or not, I took my car to the dealer and dropped it off.

I went with a ride along with the technician and he wasn't sure if it was normal or not. He said he will spend tomorrow looking into it.

Will post updates tomorrow.

I have the same issue. I brought mine into Toyota of Orange. I went for a ride with their foreman and was told the same thing as you. He says he will look into it and get back to me.

So the foreman took me for a ride in another FRS (which was in worse condition than my car), and it sounded similar but not quite.

I found it odd because I have a modified exhaust, so logically speaking you should hear more exhaust note than a whine. I have asked them to have a Toyota Rep look at the car.

I had Toyota Inspect the car and they deemed the whine is normal.

I am having a similar problem in my manual brz. Traveling at highway speeds in 6th Gear when I'm on the gas it sounds like I have a supercharger. The wine quickly Fades as I get off the gas. The wine is still audible when I have the cruise control on. Does anyone know what it could be? (66k miles,2013)

It is a light rear wheel drive car with tissue paper thick sound proofing. All you are hearing are the 100% normal sounds of such a car. All cars make the same sort of sounds but FWD hides them ahead of the firewall and even the budget sedans have more sound proofing than we do. You can add soundproofing if they bother you but don't worry there is something wrong. There isn't.

It's just gear whine -- normal for this car.

I have added sound deadening to my car (fatmat/dynamat) but it does not minimize this noise so I wouldn't waste your time with that.

I'm at 68k and I just started hearing this sound in my manual FRS. Only when cold, after driving for about 10 mins the sound goes away completely. I never heard this sound until now and I've had the car since it was new. This sound to me is not normal and indicates something is up. I suspect it is low trans fluid, that's my only thought. I'm gonna bring it by a shop to check it out. I'll update if we figure out what the issue is.

If you bought this car second hand check to see if there are yellow bushings in the diff or rear subframe, also check to see if there is one in the transmission cross memeber. These bushings people have upgraded to stiffer (noiser) for better feel of the car and shifting. If none of that exists, then it maybe a rear bearing starting to fail in the diff. Most likely pinion if it only does when on the gas and not decelerating with the clutch in. Have it checked out by mechanic.

So after listening to it more closely it is coming from the engine area. I don't hear it when not under load after it warms up. I found a video that has the exact same noise, could anyone take a look and let me know what they think that sound may be?

In the comments it is mentioned this is due to a bad alternator diode can anyone with experience confirm or refute this?

Sorry to revive an old thread but did anyone get this figured out? Mine just started doing this. It seems to go away after it warms up and I think may go away when the clutch is depressed (just started today so I haven't had much time to test it all out). I've had the car for about 2 yrs and this is the first time I'm hearing it.

your manual is acting like the op's auto problems?

IIRC it turned out to be the throwout bearing. I never would've guessed it.

More like this

It shifts just fine so I don't think anything is up with the tranny/clutch but the sound changes when the clutch is depressed.

It sounds pretty similar to this which sounds like it may different from the OP's problem so I may keep searching or start a new thread. I took a couple vids I can upload after I get off work the should help get to the bottom of it.

Pretty much guarantee it is the TOB. I could play a little song with mine just by varying the pressure on the clutch. Always went away after it warmed up.

After looking up vids of throwout bearing noise, I'd say you nailed man. I'll check threw the diy and maintenance sections and see how simple/complicated the job is. Hopefully it's something I can do myself. Thanks for quick replies guys.

It difficult if you can get the car up in the air and have some basic tools.

Hey yeah it sounds like the TOB. In my case I can confirm it was the TOB, check the thread I started for my issue: http://www.ft86club.com/forums/showthread.php?t=121318

I've got tools but no jack that will fit under so I guess it's a no go.

Thanks. Do you remember how much it ran you to get the TOB replaced?

I'll still probably post the vid when I get off but it sounds like you guys have already figured it out.

There is a service bulletin for it so if in warranty it should not cost anything. If out of warranty and you talk nice to the dealer they may still do it.

Yes but keep in mind I'm in Northern California (Bay Area) so prices may be a litte different. Also I had a trusted speciality shop theracersline do the repair who does great work for reasonable prices.

TOB full cost was 460 I think (+labor). I got a new clutch kit installed so I paid more than that. I think my total was 650ish. Honestly I could be off by $100 on both prices.

The bearing should be around $50 for the part.
