I'm still having that crunch from 1st to 2nd. I'm starting to not worry about it too much. It's annoying, but it's a slight trade off on such an amazing car. I'm also finding that the harder I drive it and the faster I shift from 1st to 2nd the shifts are smooth almost every time. It's only when I shift around 2K RPM or lower into 2nd that it grinds. If I'm shifting up around 4K or 5K its smooth. Also if I rev match the next gear it's smooth. But if I'm driving around like grandma it gets rather crunchy on that 1 to 2 shift.

Yep, so I was sitting in the garage waxing it tonight and decided to try that shifter again.
All below is with:
Engine is off.
Clutch is out.
With the engine off I can really hear the gearbox.
It goes into 3,4,5,6 smooth as butter, but every 2 or 3 times I try going into 2nd I can feel the crunch and it wont go into gear without a lot of force. Once I hit that stop point where it wont go into gear, if I go to another gear and then back to second it drops right in with no crunch sometimes. Seems to me something isn't quite lined up on that 2nd gear pack. Any gear heads out there have advice?
Thanks,

I now have a crunch into 3rd gear and I cant go into 5th without shaking the shifter. I hit a bar or notch going into 5th every time now. It's up right to 5th, then shake it, then push it back up into 5th. Also, I've had the shifter kicked back out of 3rd two more times now. I go up into 3rd, then let the clutch out and onto the gas heavily and have a grind and it kicks the shifter back out of 3rd. Serious transmission problems on this car with only 17,000 miles. I only have 2,000 miles on it since I purchased it from a dealer, so it was damaged before I got it, such a shame.

I'm afraid to take it to the local dealer, I purchased it from a BMW dealer 215 miles away so I'm worried the local dealer will tell me to take it back to the selling dealer. I would like to think that the local dealer would treat me right since it is one of the top priced cars they sell. M6, M5, (maybe 750 line) then, M3. I'm worried they'll also accuse me of screwing up the gearbox and deny warranty on it.

Update on my situation:

I have a 2008 e92 m3 6spd that I ordered new in 2008. The car i test drove before ordering (a 2008 6spd M3) ground from 1st to 2nd at high rev shifts. When I took performance center delivery, the 2008 M3 I drove ground from 1st to 2nd. My car ground from 1st to 2nd.

Before people start moaning - I know how to drive and this is a common issue. My buddy has an '09 and when I drive his M3, I don't have a problem with high rev quick gear changes from 1st to 2nd. Nor did I experience this issue in my e46 M3 or any of the many manual tranny cars I've raced hard on track (C5 Corvette, Porsche 911, Mazda Miata, e46 M3s).

I went back to Spartanburg for M school - they had switched to DCT but I was given a suggestion that has proven to work in most situations even though it makes no sense to me.

Like everyone else, I decided just to accept the flaw and move on, BUT for those of you that drive with the comfort access package - have you experienced the grind when the key is actually plugged in?

I'm not sure if something worked itself in with the gearbox or if the solution really comes from the key in the ignition, but after actually using the key, I've been able to shift hard and fast from 1st to 2nd (with DSC disengaged, I even get that chirp I so missed from the e46 M3).

Give it a try...

I never drove my old '08 M3 with the key in. Anyhow, high-RPM 1st-to-2nd shift was always good. The problem in my case was low-RPM 1st-to-2nd shifts...

Thanks for the tip, but key in or out doesn't make any difference on my ride. 1 to 2 is a crunch and 3rd now has a crunch. I think I've concluded that the teeth are chipped inside the gearbox because sometimes I cant select some gears without going to another gear first and then back to the gear I want after the car has rolled.
For example I cant select 1st gear at a stop sometimes unless I either let the car roll a foot or use 2nd gear to roll the car. Basically with the clutch to the floor the shifter will not go up into 1st gear. I'm hitting a solid object and no matter how hard I push it will not go in so I think I have some broken teeth or something is bent inside the gearbox. Maybe it's just a synchro problem??

A lot of times now if I am heavy on the gas the gearbox will reject 4th gear with a spine chilling grind when I try and push into 4th gear in high RPMS. The dealer said the clutch wasn't fully releasing which caused the problems, but now after several MAJOR gear grinds I think the gearbox teeth are fawked up and they wont honor any work on the car since they say it's a clutch problem. I'm very close to trading this car in. It only has 19,000 miles on it and I really have loved it, gearbox aside, but if the dealer wont stand behind a $70,000 car i'm going to take my money to some other brand who will stand behind their flagship car. I would expect a dealer to just about bend over backwards to make a customer happy with their product when something is clearly wrong with it. Especially when we're talking about a product in this price range. Honestly, I've not felt any kind of support from bmw even close to this level and it's rather pathetic. They just want to point the finger back to the clutch because they know the clutch isn't covered. It's clearly not a clutch problem. It's a real pain sitting at a traffic light and you try to select first gear to pull out into traffic to find out the shifter will not move into gear so you have to select 2nd gear and slip the clutch to roll the car, then go back to 1st gear to get it moving. I sit at a light out of gear normally with the clutch up so when I want to move I need to select 1st gear and the damn shifter wont go into gear. Please tell me that's not normal for these cars. It's a real shame that something as simple as a gearbox can break my will of owning another bmw product.

Edit: I forgot to mention I am unable to produce that 1st to 2nd chirp on my car during a high rev clutch release that you talked about. I've seen videos online and read many times that these cars can flat out spin the wheels from 1 to 2 and then chirp 3rd under full throttle. Is my clutch slipping?
is a 1 to 2 spin to be expected and a 3rd gear chirp?



A very dissapointed BMW owner

If the car has hydraulic clutch, then you should bleed the system or swap out for fresh fluid.

Yes sir, the dealer spent a week looking at my car for the gear crunch and they concluded there was air in the hydraulic clutch lines and they said they needed bleed the clutch to fix the problem. They did that work under warranty, but when I got it back it still had the gear crunch, but also now the clutch slips under load as described above. It feels very mushy. I am unable to product a 1 to 2 tire chirp during a flat out run. The clutch slips into 2nd for about a half second so the tires dont chirp. 1st gear will still spin the tires, but the chirps are gone from 1 to 2 and 2 to 3.
I know i'm just venting, but I worked very very hard to afford this car and I'm really torn up that it's not right and the dealer wont make an effort to replace my transmission when there is something wrong with it.

-Thanks,
Regards,

They didnt bleed the system properly. Clutch could be going. Could be bad throw-out bearing.


But first try this;
If you know how to bleed the system or know some one who does, change the clutch fluid to Super Blue. Upgrade the clutch line to a braided stainless line.

So, i've grinded this car and my E46 M3 a handful of times.

I have an 08 and I'm pretty sure it still has the clutch spring. Do you think I have a shot at getting new tranny? I really think that would not be enough to solve the 1 2 grind problem, as I do think that's just how the BMW MT is.

Can anyone with an 08 who's gotten a new tranny advise on whether this problem has gone away?

Who told you that? Clutch, tranny, and shift mechanism are purely mechanical man. Your 'finding' tells me you need to work on your technique .
By the way, try shifting to 1st right after pushing the clutch in, while the input shaft is moving. With vehicle stopped and tranny stopped, there's always a possibility gears are not properly aligned, and no amount of pushing will engage 1st. Normal for any manual tranny. And no, synchros don't work when nothing is moving.

I, at 30k miles, just got the car to go high rev into 2nd and (DSC off) chirp the back wheels. On a nice straight, I can get a quick chirp from 2nd to 3rd but I've always been able to make that happen (there hasn't been an issue for me shifting from 2 to 3 at the top of the rev range).

Hey man, like I said, I thought it was BS too - but the guys at M school told me that they needed to change to DCT b/c of all the issues with people slamming their cars from 1st to 2nd. They suggested starting the car with the key in - something that they claimed help.

As i said - no idea what in the hell that would do to the tranny.

And lastly, my problem isn't with 1st gear - those are other guys posting - my issue is with high rev 1st to 2nd....

I've had 1 grind from 1st to 2nd at close to redline but I'm attributing this to 3 years driving a twin clutch (Evo X MR) and basically using 2 fingers to pull the shift lever back to upshift so I wasn't using enough force in my 6MT. I haven't done another redline shift yet but have noticed that downshifting from 3rd to 2nd is very notchy (but no grinding). I basically have to double clutch if I want to go from 3rd to 2nd at high RPMs (over 5 - 6K).

Anyone else have downshifting issues at higher RPMs from 3rd to 2nd?

I've already notified my dealer and he's told me to bring in the car but I'm going to test out the tranny for another week or so and see if it's my technique.

Just grinded 1 to 2 again under hard acceleration. Wtf!?

Are you supposed to shift through the grind or back off and start the shift over?

So embarrassing though. Two people on the sidewalk looked at me like what is he doing to that poor car?? Mind you i have been driving MT for over 10 years.

The only times it has done this is when I am launching from a dead stop with some tire-spin present.

I had my old G-tech hooked up the other day and was messing around with 0-60 testing. During my testing, I launched the car at too high RPM a few times which resulted in severe tire spin rather than a good launch. This is when the grind problem really showed up. If I tried to shift into 2nd quickly at redline (and very low vehicle speed due to wheel-spin), I could not get it into gear. This happened 2 times, I believe. If the car hooks up well and is not spinning the tires when shifting gears, I seem to have no grind problem at all. I can shift quickly without issue, although there does always seem to be a bit of a delay engaging 2nd gear, much like any other manual car I have owned. 1-2 shifts are always the hardest to nail fast.

Oh, and I am a BMW Master technician in California. I can tell you that I will not be ripping out my transmission for this problem, unless it gets a lot worse. Judging by the number of us that have experienced this problem, I'd have to say it is an engineering flaw (or just the way they are). I think I am just trying to make the transmission do something it does not want to do.

For those of you that want BMW to replace parts to fix this problem; I would suggest taking the service manager or shop foreman for a drive to show it to them. This is the only way you will get anything done. It will be unlikely that the tech will be able to duplicate the problem, and I doubt you want them beating on your car to verify it.

If anybody in the area wants me to look at this problem for them, I can try to get the ball rolling. If I can get the problem to happen then it is likely that we can get some parts replaced to make you happy. Send me a PM if you'd like.

Do you think the slipping load, due to tire spin, prevents things from syncing up in the gear box? Not enough load? Just curious.

I've had the grind on high rpm 1 - 2 shift happen a few times during the first roughly 12000 miles. It happened occasionally on my previous e46 M3 as well.

Right now the car has about 30000 miles on it and it has been a long time since it has happened. Last week I did a few hard 1 - 2 shifts to see if it would happen again and I couldn't replicate it.

It may just be that I got lucky, but it does seem like in general the car shifts smoother now than it did when new. I've never had any issues with grinding in any other shifts or at lower rpm/load.

Does anyone elses car seem to shift smoother now after 25000+ miles than it did when new?
