Edit: and is this the right part number for the m3 tranny mounts that fits our cars? 22322282340...

I did mine a couple weeks ago. I have not read anything that suggests that the associated bolts and nuts need to be replaced when changing transmission mounts. They are not highly stressed fasteners. The torque specs are relatively low. I would be surprised if there's any reason to change them out.

Still getting to know my car and I see it has a tire pressure button on the dash. Is this standard TPMS or something earlier? Should I be concerned that my winter wheels don't support TPMS as far as I know?

Yes it for the tpms, but it works based on wheel/hub speed and does not have a pressure transducer on the wheel so you should be ok with having winter wheels on...

Called the dealer to get an estimate on a transmission fluid flush but said they don't recommend it unless i'm noticing a problem with it because it releases any gunk already inside and i could have problems in the future. Was surprised to hear this.

I think this is why some people recommend a drain-and-fill as opposed to a flush. The drain/refill doesn't stir up crap like the flush.

1) What's the consensus on the guibo/flex disc? My car only has 44,000 miles on it, but it's also going on 12 years old. I know rubber gets pretty hard over time. The reason I ask is the car will be on stands in a week or so getting wheels refurbed and I'll be under the car doing FCABs, and I was thinking of a couple of other easy things to do while I was under there. I don't want to just throw money at stuff unnecessarily, though. Has anybody changed it and noticed a significant difference in NVH?

2) When I get out of my car, there's quite a creaky sound coming from the left-rear suspension. I know it's the suspension unloading, but the creaky sound sounds like a pie tin or sheet metal. Any thoughts on mitigation? I should probably do a rear suspension refresh at some point, but it's down the list a little.

Thanks!

I think my post got lost in the barrage of Bluetooth/telematics posts. Any thoughts on the guibo or creaky rear suspension?

Thanks!!!

Has anyone taken the 3rd brake light off? Is it easy? I noticed the area in there could use a good cleaning on the glass and on the plastic.

I say replace the guibo. It's a cheap PM. I'd look into RTAB's or RSM'S to eliminare the creak. Could even be the rear shock for that matter.

I've had the cover off before. Very easy to remove the cover, then assess how to remove the light. It's most likely fastened with a couple of screws accessible from under the cover.

Edit: looks like clips.

Thank you, sir! Moving that stuff up the list!
