Waldorf · 07-30-2007, 02:40 PM

thanks guys, keep the info coming and include production dates

155MPH · 07-30-2007, 08:10 PM

My production date was the third week in March, 2006. But wouldn't you be more interested in the production date for the tranny?

the transmission is not an M3 item but one from a Z4 3.0si (that's why there's no SMG) but they never bothered to beef it up, so the synchros are not made for 340hp. they just fail to synchronize 1st to 2nd at over 6500 rpm.

one guy, here in Montreal got a new tranny. I'll be requesting one too and there are more people that we know with the same problem. we will expose this to the press in a bad way if BMW does not acknowledge it quickly.

if anyone has this problem, OR ANY OTHER, with the transmission in a Z4 M Coupe or Roadster, please post here.

thanks

I thought the same when i started to have the problem around 1000 miles. Thats when i started to pushed the car a bit. So what tranny will they replace it with. If they put the same one in it will just do the same, no?

so far, that's the problem. there is only one part number for the tranny and nobody knows if anything inside has been uprated.

Alex, with the blue Coupe in Montreal, who got a new tranny says that this one works correctly but still has the same part number.

If BMW caught the problem and fixed it, we need to unite and get a proper recall. That's why i'm building a case for everyone's benefit.

Saw a post over at bimmerfest where the Dealer was instructed by "Germany" to adjust the clutch and shift/gate linkage? Any updates by anyone else?

Waldorf · 08-10-2007, 12:45 PM

do you have the link?

my car is still at BMW Laval and BMW Canada sent a lead engineer from Toronto this week to work on it. He's been at it for three days now.

just got my car back yesterday, but i can still feel the notchiness, but since i understand this problem, i avoid it, but i hope this tranny gets totally recalled, what a POS!!

SunnyD · 11-23-2007, 12:01 AM

Just wanted to bump this thread to get an update from people who took their cars into bmw to have this 2nd gear synchro problem addressed. I've been experiencing the same problem lately and it's pretty annoying.

Artz 330 · 11-23-2007, 07:32 PM

i have a new trans. its re-engineered different part no. the new trans is sweet.

Hi,

First post.

Two week owner of a 2003 3.0. It has been 6 years since I previously owned a car with manual, so I thought the grind into second was my fault when test driving. Anyways, it is persisting. It doesn't happen quite as often now that I am somewhat adjusting to this idiosyncrasy. It still sucks. I can't shift hard into second. My 1983 Audi Quattro had a better gear box.

Most of my grinds happen when I am above 3000 RPM when in first gear. The gear grinds when I shift into second even when I have the clutch depressed down to the floor. The only time when it doesn't grind (most of the time) is when I can dump the clutch within a split second of my shifting into second while maintaining the RPM within a few hundred between gears which is pretty difficult to do. Also, it doesn't grind when I let the RPM drop below 2000 RPM before shifting into second which is what I do most of the time.

One person stated in another post that he removed his CDV and installed a SSK, and his 2nd gear woes went away. I think I will go that route.

etane · 11-27-2007, 03:56 PM

Hi,

Third post,

Second gear grind symptom has dimished quite a bit since my last post. Perhaps I am more accustomed to driving the Z subconsciously more cautiously when engaging 2nd gear.

Also, I got a ZHP shift knob lastnight. I've been driving the car without being consciously cautious when engaging 2nd gear all day and didn't grind at all. In fact, I tried to get it to grind by shifting "normal" and still no grind. There's still a question of excessive notchiness when going into 2nd gear (1st gear isn't that smooth either half the time). The other gears are smooth and engages with more alacrity and is more assuring.

Maybe I am "burning in" the gears...

Dammmittt · 11-27-2007, 05:30 PM

Mine doesn't grind anymore either. Artz what's the part # on the new trans?

epbrown · 12-04-2007, 02:20 PM

Yeah, being the market I'm curious about this as well; did you get the new part #?

Also, Car & Driver mentions 2nd gear grinding in the August 2006 issue comparing the M coupe to the Porsche Cayman.

killjohnnyforan · 12-10-2007, 09:04 PM

artz, i need that part #!!

Artz 330 · 12-10-2007, 10:52 PM

runnerx · 12-19-2007, 05:59 PM

mine grinds too...

speedygirl · 12-19-2007, 10:37 PM

Or you can just start off in 2nd gear when you're not in a hurry. Like when you're trying to get out of a snow bank...

Mine was grinding too.

Took it to dealership and they replaced the entire tranny.
Shifts like butter now.

Took the car to Bob Smith BMW in Calabasas, CA. They replaced it two weeks ago.
