G37 7speed transmission reprogram
It's really a matter of how good the Service Manager is... sets the tone for the service dept. Sometimes it's even the culture pushed down by the GM.
Shop around all the dealers in your area to see who is the most helpful and then stick with them, regardless of their pricing.

I've said this before. You have to look at it from the tech's pov. Day in and day out they deal with clueless or even worse semi-clueless customers, all swearing up and down that they know what needs to be done etc. How are they supposed to know that you are the one in a hundred person who knows what they are talking about? Only way to get their attention is proof, so have a way to (safely) video with audio record whatever issue you are having. Showing them that will instantly change how they deal with your problem.
For clarification, the device is called the JCR CAN recorder. It has been designed specifically for use in Nisaan and Infiniti vehicles equpipped with 7AT.

My car is at the dealer now (for other things as well). I didn't really have much issue with the trans except for recently when I tried to cut in front of oncoming traffic and the car sat for a sec before going.
I'm curious what it'll be like when I get it back. I'll post up.

Just got it back and. Was in a hurry when picked it up so didn;t look over paperwork until I got home. ..They did the ITB10-075A 
Apparently from another thread it depends on if the use the consult III or consult III+ ???
I'm going to call and take it back in and show the ITB printout and explain about 027.

Received the upgrade to the latest SW today and it REALLY makes a difference driveability of the car. The transmission is much more responsive and no more jerking during deceleration. I had been having buyer's remorse but I am now happy again - the G has much more PEP!
The dealer DID have problems locating the upgrade but the shop was empty and the service manager was cool. After arguing with me and even showing me screen snapshots that showed no update available, he agreed to print off the TSB and check out the TCM part number. He then had a different tech connect the consult 3+ to the car.
Apparently there are two ways to connect to the car - the first auto detects the model and the VIN. When connecting to my computer this way the consult 3+ did not show an available upgrade.
The tech then manually selected my make and year and both the TCM and the ECM SW upgrade showed up. The service manager was very surprised and had them upgrade it on the spot.
If your dealer doesn't believe you have them print out the TSB and grab the TCM and ECM SW part #s and compare to the actual versions in the car. My dealer insisted I had the latest SW because no upgrades showed up in the consult 3+. When I asked them to check their records to see if any TCM upgrades had been performed they couldn't find any. I then made the point that I could not have the latest SW without an upgrade so he agreed to look again.
Thanks to all who shared their experiences in this thread - couldn't have done it without you.

By the way, the most recent TSB is ITB12-027c (8/29/2012) and can be found at the link below.

I printed both ITB printouts for comparison and also some of your post explaining the reason why 075 comes up on the consult three. I'm in the waiting room now. Service manager took the documents back to the tech... we'll see...
I just had TSB ITB12-027c applied to my car. What a difference! No more lag when I hit the pedal while cruising or harsh downshifts. If your car qualifies and you haven't had it done, do so quickly!
