Shudder at 40mph (~60km/h)
I think it did..but when my car went in for a brand new engine..they had to put in 3 qts of trans fluid..so i think it diluted it.
Right now i am still worried about my vibrations at highway speed..then i will worry about shudder lol
It seems when the trans is cold it does it more. As it warms up it does it less..or it seems that way in my case

Looks like you guys are not the only ones with auto tranny issues, Honda has issues of its own... This worries me cause i have a 07 TLS and was browsing around the acurazine and was a bit worried to see some people complain about their trannies dying out due to running on the wrong software for a long period. 
Just hope its not that common.
Hope all these companies can fix these problems soon since it seems to be mostly software related.

^ the problem is not whether they can build a car without issues, its the lack of consistency. You will always have a bunch of people who have the same car as yours with zero problems over the entire life of the car, while you would have another bunch experiencing all sorts of problems within a few years... i guess its more of a luck factor.
The problems that are common among all cars sold are usually corrected by the mfg cause of complaints from all its buyers.

AT SHuddering problem 06 g 35 coupe
Hey guys, definitely not a wheel balance issue. In fact, just to be sure, I had them rebalanced in the summer. From what I've read, and what my mechanical knowledge tells me, is that the torque converter is locking/unlocking at that speed range.
To answer your questions:
-Yes it's an auto, 5AT w/AWD (this problem is not with the AWD though).
-By shudder I mean holding the car at 40mph (60kmh) at a steady cruising speed (but not in cruise control)
-It feels as if the car is going over ripples on the road, slightly bucking forward and back really quickly, mossman said it best: it feels like you're in a manual car in 5th gear when you should be in 3rd, the car bucking and "shuddering"
-I attempted swapping over to DS (sport) when I feel shuddering, and it does not go away (unless the gear changes)
-It happens on level roads, and inclined roads. you definitely feel it more on inclined (uphill) roads. haven't noticed it going downhill.
-It's doing it at approximately 1500RPM
Wayne (gee35x): So this surging/bucking only happens when you're in cruise control?
So some of you guys are having this issue as well, you know what I'm talking about then, hopefully all our minds and efforts together will get this dealt with.

Also, what is reflash? (pardon my ignorance-I'm new at this)

i have the same issue but there is another post in the main section that talks about the software update for the g35 ecu which was available, supposedly this fixed the issue. i have not yet made an appointment to get the update but i will report back when i do.
a "reflash" is literally re-loading the engine computer software.
