Thanks, I will see if this remedies down shift clunk problems using paddle shifters from the base 027 flash.

 

This is the one they did to mine a few months back. I had asked for the newer one but service mgr said this is the one that was recommended.

It works like a charm. My issue was with either failure to downshift coming out of a speed zone unless you basically floored it, in which case it was ***** to the wall. You were grandma or you were Earnhardt. Not any more.

 

Well guys, I MAY have made a big impact on the issue regarding some people being told and or getting 075 instead of 027.

A page or so back, last week, I took my car back to the dealer after realizing 075 was applied to my car instead of the more recent 027. 027 clearly explains the issue I was having, lag after coast, whereas the 075 does not.

I took with me a printout of both the 075 & 027 ITB, a copy of TVpostsounds explanation from this thread
https://www.myg37.com/forums/tsb-tec...ml#post3537750
and also another technical explanation from someone in this thread that I can't seem to find.

I provided it to my service adviser pointing out that 027 applies to my vehicle, is more recent, and explains the issues I'm having and also pointed out that 075 did not cover some of my issues. I then explained the forum printout and why 075 may have been applied to my car instead. She called the service manager over, who looked at everything and asked me to wait while he presented them to the tech. He came back about 25min. later and said they only have 1 of the 2 consult III cables and that he has a call in to corporate. He said he'll get back to me with a response later in the day. His response & demeanor led me to believe I was going to get nowhere and in the boat of some of the other posts here.

HOWEVER - I finally got a call today. He said he wanted to update me so that I didn't think he forgot about it. He explained that coincidentally the corporate service person was suppose to be coming in for a big meeting on Thursday, and he was told they are going to go over the documents and look into the issue then. He said he'll get back to me late Thursday or on Friday.

He basically implied that they are going to look into if there is some sort of fault in the system or reason why some vehicles are getting 027 and others are not due to which consult III system or cable they are using.

Maybe a fix nationwide!?

 

Does anybody have the name/extension of a knowledgeable Infiniti consumer affairs rep about this issue? Mine is totally useless. Thanks

 

At the dealer I used there were NO CABLES. The tech explained to me that the computer can connect to the ECM and the TCM wirelessly. The consult 3+ is an interface - not a connnector.

I had the 075 TSBdone back in June and it fixed the down shifting but there is still a tag in pressing the gas pedal from a stop or even a rolling stop. Should I take it back? Would the TSB even take care of it?

 

Interesting. Tvpostsounds link didn't make complete sense to me about the cables, bust assumed it would to the tech. However if your saying it is wireless, there would have to at least be a wireless dongle they plug in to the obd2 port. I highly doubt the vehicle itself has wireless capability.

 

Thanks, Brian.

So for those in the know, what's the difference between 027c and the earlier versions (027a in particular) besides the list of vehicles it applies to?

 

Did you have the 'c' applied over the 'b' or was this the first and only reflash you had done?

 

I had the 27c TSB applied over whatever was applied in late 2008 (my car is an early 2009). It was the first reflash. Can't believe the previous owner never took any action.

Not totally sure but I think the difference is just an expanded list of models. For example 27c covers the convertibles but 27a did not. THe bulleted list of symptoms across the two TSBs remains the same.

Consult 3+ can communicate with the car's computers via Bluetooth or via the OBDII port.

 

Yeah, I think so too. The PDF from infiniti suggests there is no technical difference if you already have 'a' applied (which I do, and why I asked you that question- thanks for the info!)

 

This is a post of current experiences since the reflash was done. I've got over 5k miles since I did it:

• Generally, much better driveability with less lagging. BUT, it does wield it's Ugly Head at times. To me, I still experience too much of a variance in the way the car drives- one day can be a a little different than another.
• Although the coasting of the tranny is better since the reflash, still too much herky jerkiness in gear changing.
• DS mode is drastically altered in the way it performs.
• Beofre and after the reflash, at times, it is a little hesitant off the line. For example, when coming to a stop at a toll both and then hitting the gas, I feel a little hesitancy. With hard throttle, she moves and changes gears well. With less throttle, from a stop, again at various times, the car exhibits more of that jerkiness in shifting..

I would only give a serious look at the new G (Or M) when my lease comes due next June ONLY if this 7AT is really Modified and improved.

 

Have you driven an M to see how it's transmission behaves?
