Wow that's strange, I noticed a huge improvement on low end acceleration. Yes my car at stop lights idles at 500rpm. But when starting car and driving the Rpms are around 1k plus rpms
I never had the bad vibration ur talking about. Mine only gave a slight vibration when putting in reverse for a second. Seems like there might be something else wrong w your Cvt or unless they didn't perform the Tsb correctly

My Nissan keeps telling me that it doesn't apply to my car but yet I feel the sluggishness too.

Go to another dealer. !!

sluggishness isn't a symptom of the TSB. You need to report the symptoms of the TSB. Tell them you feel a vibration when the torque converter locks up at 30-35 mph. that's the point at which there is a "booming" or "vibration".

I think the flashing has also made it such that the torque converter seems to unlock faster than before too possibly leading people to perceive an added snappiness.

It appears that it doesn't matter what I tell them, they're simply looking at the year/date of manufacturer for what model year, month it applies to.

As far as the sluggishness, I used that phrase because supposedly this TSB makes the car take off faster to 40 than without it.

I will go to another Nissan at Lunch to see if they can apply it there.

Having the 2011 maxima, do you think that this TSB was already applied considering the fact that this TSB has a date of 12/18/09?

Confirmed. Got car back today. Very noticeable difference.

Set up an appointment to have the TSB-138 and the Nav/Callwaiting issue worked.
My 2010 has a build date of 12/09 and hope like hell the reflash will apply.
I figure the reflash to kinda equate to when you first drive the car before it warms up. It has that nice (higher RPM) acceleration. After warm up the acceleration suffers, especially after slowing (in "D") at lower speeds and THEN getting on the gas.... bog city.
I don't actually hear the so called "booming noise" that is mentioned, just a lack of response from the CVT and you almost need to half-way bury the pedal to get it to respond.
I find myself using the the Ds and M mode to compensate for this CVT issue.
Also, it would be interesting to know what Nissan did to the later model 7th gens to aleviate this problem. It obviously wasn't anything like this fix as the newer models do not suffer the 1-2 MPG loss often seen with the TSB-138 reflash.

It's a subjective measurement. I've never seen any hard numbers proving this. I, for one, didn't "notice" any difference other than the fact that the torque converter lockup doesn't occur until a higher speed is achieved and the engagement seems is somewhat slower.

I took my maxima 2011 to the dealer and they placed the computer on it and they came back telling me the car is perfect I dont need anything. I still dont know if indeed the 2011 is fixed or I need to go to another dealer and make my case in another way. They made me test drive another maxima which I found the problem even worst on it than on my car.

Ok, went in to the dealer today to get the Nav/call waiting fix done on my 14K 2010 and also the TSB-138 for the CVT slugishness issue.
Before any work was attempted we went for a test drive with the service tech driving.
He agreed he did feel some (a little he said) of what I considered was the hesitation concern and said he would check to see if the TSB138 applies.
The service person reported back the they completed the Nav/call waiting fix and then said that yes, the CVT had an issue and they were going to order parts (valve body, etc.) and that I would get a call when the parts came in.
So just a reflash the CVT wasn't going to be done. I haven't had any other issues with the tranny so this is kinda puzzling.
Has anyone else experience this?

Now I'm wondering if this is just the dealerships way of making a buck from Nissan to do this "valve body" work or did they really find somethig that required repair? Which is what one would expect.

Also thinking if everythig is done and corrected as they say I could actually be benefiting from a CVT repair that will likley include...

1) A valve body relacement to bring the CVT up to the 2011-2012 configuration and not lose the so-called 1-2 mpg of just a reflash.

2) And of course get a complete CVT fluid flush and refill out of it when all is said and done!

Input please...

Got the car back from the dealership on Sat with the new valvebody installed in the CVT. It does accelerate much better.
The tech said it now has the 2011/2012 configuration. No TSB-138 reflash
was accomplished.
The dealership is holding the repair order open so I can drive the car for a couple of days in case I notice any other issues with the repair.
I plan on stopping back in to pick-up the repair paperwork this week.
I will report back on what the NTB number was. I think the tech said it was NTB11-002A....?

My dealership wouldn't do the TSb because they couldn't duplicate the issue.

eesjunin

weird...mine trusted what i told them...plus they checked the vin and agreed that my vin was in the TSB range...I would force them to show you the tsb and vin numbers that are affected...and see for yourself

Go to another dealer

i know this is a old thread but i think newer guys like me with a 09 will find this interesting, so i'm responding to this to get it back into the discussion

Just bought an 09 SV with 13k and these symptoms. Nissan tech ran VIN but it doesn't qualify. What next?

dr_2010SV

I was told when I had mine done that the NTB11-002A valvebody replacement applied to the 09 and 10 models.
Also the tech still has to drive it and be able to replicate the problem.

Like WHIT says ^ above...go to a another dealer.

Got this done today and my car does take off with alot more response and so far gas mileage hasn't changed much. But I was struggling to get above 19mPG on average on my car but come to find out I had a "fuel gauge leveler" problem and since I'm cool with the service guys, I'm getting a whole new fuel pump assembly just in case because I am almost out the warranty 59k. So I will get back to the thread when I can get an accurate reading!

Sorry to bring an old one back but if I reset my ECU (unplugging my battery) will this erase my TSB on this? Thanks!!
