Transmission Update from Dealer?
Hi, I just started reading the forums and have found a couple threads from a couple years ago that mention a transmission update from the dealer, but I cant find anything saying what it actually does. How would I check to see if my car has this update and if it doesnt what would I ask the dealers for to get it?

A dealer can tell either with your VIN # if it was done under record, or by plugging into your car with their scan tool to see what version your car has currently.

Not 100% sure. From what I’ve read, mostly downshifting issues and harsh shifting issues. When I first got my G, I had poor shifting. Surprisingly, I disconnected the battery and installed a grounding kit, and never had the issues again. Not sure if the grounding kit or a battery reset cured my issue, but one of them did, and I never pursued the transmission update. If you search this forum, you will find tonnage of information on the subject, including a TSB about the update.

My 2011 was updated in early 2012. Shifting in D was much improved with less hunting and hesitation. DS was neutered IMO! Not as quick to downshift when getting on the binders. Overall It was a good fix overall.

I had two of these TSBs installed by dealer:

May be what you're looking for. Definitely improved the smoothness of shifting as well as rev-matching quality.

Wow, thanks for the PDFs, I have all those symptoms. I just figured that's just how it is, didn't know there was a fix for it.
When I go to the dealership, do I tell them specifically what I need or just say the trans is shifting poorly? Also, will they be able to tell or look into things that would let them know I have an ecutek flash?
