I forgot to ask you, when you swapped yours did you end up getting harmonic resonance / vibration around 1400 and 2100 rpm? I still haven't been able to track that one downIt's almost time for the best part! :devil
Yes. If I'm sitting at idle and I give a little gas, I get a little harmonic vibration that steadily gets worse until it hits ~2k rpm then it suddenly smoothes out beyond that. I ended up using the LUK flywheel/pressure plate. You?I forgot to ask you, when you swapped yours did you end up getting harmonic resonance / vibration around 1400 and 2100 rpm?

Interesting, I get the same harmonic resonance at two frequencies (1400 and 2000) - it must be the manual flywheel. My wife's SMG doesn't get any of these harmonics.Yes. If I'm sitting at idle and I give a little gas, I get a little harmonic vibration that steadily gets worse until it hits ~2k rpm then it suddenly smoothes out beyond that. I ended up using the LUK flywheel/pressure plate. You?

GabrielD - I actually managed to fix the issue on my car. So what I ended up doing was using NCS Expert and re-coding every module of the car with the 2MA option software. Once I did that, the error code went away and haven’t seen it since. I think what happened was I never properly coded the car and the DSC software was possibly looking for signals from the SMG ecu that is no longer there. Either way, I’d try re-coding the car using NCS Expert and go from there.
I got the 6-speed flywheel and clutch in and torqued on. That flywheel is HEAVY and AWKWARD to get into place. A second set of hands may help. Realize that there is a dowel on the crankshaft that a larger flywheel hole with slot into. You need to get this right otherwise the flywheel will not sit properly and can cause serious damage. Torque to 105nm.
Getting the clutch was also a bit of a hassle as well imo. It’s an odd type that it has splines inside the pressure plate that line up with the clutch disk. If these aren’t lined up prior to mating it up to the flywheel, you will have a hard time trying to get the pins on the flywheel lined up with the holes on the pressure plate. Make sure your clutch comes with the alignment tool that has the detachable bolt. Once that is done, torque the pressure plate to 10nm+2nm. You will then remove the 14mm allen lock ring. Take out the alignment tool.
It’s been a long night but I got it on and ready to prep the trans tomorrow. More on this shortly!
Thankfully I had luck finding a manual shaft on eBay when I did the M5 drivetrain conversion on my E61 but since I paired it to the N54 motor I needed to add length and the shaft was rebuilt. That being said you can just buy a SMG shaft and have it lengthened/rebuilt. I paid $150 for the driveshaft on eBay and then another $600 to have it rebuilt and lengthened but I now have a brand new driveshaft, not ideal since but something to consider just make sure the shop is qualified as the BMW shafts are more involved to rebuild, not a simple cut and weld like some may think.This thread has been very, very helpful and thanks folks for answering my questions.
Does anyone have any idea where I can get the drive shaft (PN 26112283210) from? Car Parts doesn't show any. I actually told a place in CA that had it that I would take it. They said they'd take it off the car and call me back. Never called me back. When I called 2 days later, they said they sold it 2 days ago! Still getting the tranny from them, though.
The only other part I'll be missing after the driveshaft is the second half of the wiring harness, but I figured I'll just have to work around that.
Thanks.

Hi ChariotNew clutch kit has arrived:
I must admit, I was expecting it to be bigger. Not to mention I wasn't aware the manual used a dual friction disc setup similar to the SMG.
Notice it also came with the updated style release bearing....very happy about that
Updated total inventment so far:
Pedal assembly: $61.39
Shifter assy: $42.16
4 Hydraulic pipes: $153.05
Transmission (Found a different transmission than originally planned): $944.00
New Clutch Kit: $400.38
New Flywheel: $449.78
EDC Buttom w/trim: $40.00
Misc. Dealer small parts/odds&ends. (Will itemize later once complete.) $37.19
=$2128.66
The only remaining part that is required to keep the car driveable is the drive shaft. The seller is local, so I'm waiting for the transmission to show up so that I can evaluate the condition of the other attached trans. parts so that I can order replacments if necessary. Once that is done, it's a trip down the road to get the drive shaft and everything goes in.
At this point, i'm shooting for next weekend for the install.
Thanks it appears that they have different pricing when looking from UK £904 it comes with and they don't appear to do the clutch set.Rockauto, however, it looks like they are sold out at the moment unfortunately.
Looks like spareto has them though in the 500s
Is it a drop-in replacement? I may be interested. Can't PM you, but email me at "lsllll1" at "nvek" dot "com" please.I made the second part of the harness if you’re interested in it. I used the E90 M3 transmission harness that came on my used 6-speed. Let me know if you want it and can work out a deal.
