There is a new transmission update out for our cars. Just figured I would throw that out there incase some people don't follow the thread in the sedan section.
I plan on getting my done next weekend. Any coupe owners get their 09 trans update recently? Impressions?

Yes, it is 027. The 09's just got approval for the same update the 10-11's have had for a month or so now. It fixes the harsh downshift from 2-1 and the lag. Overall impressions on the sedan is "GO GET IT NOW" so i'm getting asap
My dealer also said there is possibly a prob with the '09 torque converters. Said mine will be swapped out under warranty if necessary. 
I'm not as concerned about the rough shifts as I am the stuttering at constant speed around 40 mph and at 60 mph. Like riding a mild rumble strip!

And thanks to the OP for the heads up.

I expressed my issues to the service manager, made an appointment for 8:30 this morning, dropped it off, got loaner and got a call it was done at about 11:30.

I'm pretty sure I felt the 60 mph stutter but not absolutely sure.
Other than that. The car coasts a lot better and feels more relaxed in "D".
Stop and go traffic felt more natural with a a little gas and then coast back down to stop.
1-2-3-4 gear shifts are smooth like butter with small pedal input, but power is still there when
I push it down further.
26 miles and still happy. LOL

does this new TSB correct the "flare" in the transmission? where sometimes the rpm will jump up around 250-500 rpm between shifts (feels like a slipping tranny or locking and unlocking of the torque converter to early). mostly does this when you drive the car a bit then park for a little then drive again. It doesn't happen all the time, but it sure is annoying when it does!
Honestly. I don't know if this is an "update" . Meaning it includes past fixes for issues that have been rectified.
I took mine in for the stutter and rough shifting in lower gears. And shifting is great...I'll have to wait on a decision about the stutter.
But I have had no flares yet. But had some after a reset the other day.
