Just got back from dealer. ECM was re-flashed and all seems to be working fine. No signs of the 1st to 2nd shift shudder so far. One service manager said they have seen a few T4R's with this issue. A different service associate said he just had one in yesterday with the same issue and that was the 1st one he had personally seen. Until yesterday, he wasn't even aware there was a TSB for this issue. Sounds like this particular service staff needs a to have a little technical pow-wow on some current issues. He seemed surprised I knew about it. This is a great forum. I will post more if any more issues arise...Cheers:surfer:

I don't know exactly which TSB applied to my VIN. We looked up the Assembly line roll off date and saw it was NOV of 2009. From an earlier post it appeared mine fell after the VIN's listed, but maybe there is another TSB out there. I mentioned the TSB listed from the other thread 0166-10 (I believe that was the number) and he seemed to know what I was talking about. But again, I am not sure if that exact TSB is the one applied to my VIN or if there is another one issued later. There obviously is an issue because he said "No problem, we'll just reflash that for you and take care of it" I didn't meet with the usual..."There's nothing wrong, that's normal" song and dance. Just glad they didn't fight me on it and took care of it. :beer:
Harper, where did you find the diagram about changing checking the AT fluid?
Check out my sig!!
Just got off the phone with service department. TSB 0166-10 informs dealers to reflash ECM to fix hard shifting issues with ALL 2010 4Runners. I asked him if this dealt with specific VIN numbers etc. and he said from what he could see this applied to all 2010 V6 models with no specific range of VIN numbers annotated. Hope this helps.
If you pay the shop labor rate, they will wave sticks at it and paint it with chicken blood while singing Bob Marley songs. Just tell them you want it applied and they will do it, but it might cost you.Do you think they would re-flash mine with the 0166-10 TSB even if they said mine supposedly already had it done? Because I've heard people say that sometimes just doing that can make a difference. I'm not sure why, maybe do to just resetting things.
Just wondering if any of the 2011 owners have had the shudder resolved? Mine has done it from day one, with a light take off it will shudder at exactly 10mph every time going from 1st to 2nd. It is a shudder that is like three quick vibrations; you feel easily in the stering wheel. Service rep said it was breakin probably; although he said the tech could not experience it during a test drive. I suggested BS; but agreed to wait until the 5k sevice like he recommended. Now it has been two months and 3k miles since then and it is as obvious as ever to me. Maybe he meant the truck would break me in by 5k!

Mine isn't really a shudder from first to second. If I have it in park for a few hours, when i put it in drive I can feel a little pop (for lack of a better term) in the brake pedal area. I sort of half feel it, half hear it. It's weird. It seems to be doing it a little less. It's almost like a relay or a valve cycling on. 2011 SR5 with 800 miles on it.
I have a 2011 and it is rolling up on 5k miles. I am experiencing the shifting issue. Matter of fact I was playing around with it a bit today to isolate when it did it. If I floor the gas pedal it will shift from 1-2 normally... light acceleration I notice it slips causing a shuddering feeling into 2nd instead of shifting. Under manual shift conditions it shifts normally. I plan on taking it in and asking them to fix it in a few hundred miles (my 5k visit). I also notice a delay in the response of the gas pedal under similar conditions. If I slowly accelerate it can take up to 1 second for the car to respond. Feels like play in the gas pedal before the car reacts. Anyone else experiencing this?
