Did they fix your problem? I have similar problem at 119,000 miles but dealership is saying no error code generated. Very frustrated and it seems to be getting worse.1Pettinger wrote: ↑Wed Jun 28, 2017 7:20 amPurchased a 2011 QX56 with ~100k on it several months ago.
Problem: on gentle to moderate acceleration, the engine revs up and down about 250rpm. Between 4-5-6 it will actually shudder somewhat if acceleration is gentle enough. Behaves MUCH better when accelerating more aggressively. Generating P181B code (Transfer Case Control Module).
Steps Taken: Checked fluids, which were OK in level but maybe a little dirty. Assured by my regular mechanic that dirty fluid could not possibly cause this symptom. He hooked up OBD computer and checked the voltage coming through the computer that controls the transmission system (located behind the glove box) and no voltage variation was seen. Timing chain recall done at 103k.
I'm absolutely DREADING taking it to the incredibly poorly reviewed dealers here in Jacksonville, FL, but also understand that this may be the only solution I have.
Would really appreciate hearing from folks that may have had the same problem and what they did to fix it. Torque converter? Solenoid? Transmission computer? Thoughts?
Thanks!!!

Yep, thats the stuff, on my other post, i actually posted a pic of the package I bought at autozone. I drained 6qts of fluid from my pan, so I bought 6qts and I used the entire tube of shutter fix. On my other thred it shows a video on how to remove and add fluid for at QX, it is very helpful. Good luck sir!raven69david wrote: ↑Tue Feb 21, 2023 5:52 pmThis stuff?adamruiz2001 wrote: ↑Tue Feb 21, 2023 5:12 pmSee my post on this thred for the fix for a tranmission shudder...

How much did you use? How much transmission fluid did you buy from the dealer?
Thank you very much Adam. I have a follow-up question. What did you use to add fluid back inside the vehicle? What size were the drain/ fill plug sizes? I’m getting ready to do this but seems so simple I can’t stomach Infiniti charging $350 for this or $175 for a garage to do it.adamruiz2001 wrote: ↑Wed Feb 22, 2023 7:03 pmYep, thats the stuff, on my other post, i actually posted a pic of the package I bought at autozone.
