My truck is a 09/07 build date.....BUT, I have not yet had a rumble problem (that I am aware of). I think I will start paying more attention to my truck after reading this thread though! Am I correct in assuming that any truck assembled before-on 10/01/07 could or will have this problem?? Or, if I dont have the problem yet, is there a likelyhood that there will not be a problem? I am a little concerned about this
Wow, those are two questions I definitely am not qualified to answer. However, I would not be concerned because I think most of us who have had the rumble problem had it immediately. In my case 2nd day of ownership with less than 100 miles on the ODO. FYI, just so you can know how I could duplicate my issue every time:
1. Drive down HWY at normal HWY speed for a few minutes and come to a stop (light or stop sign).
2. Easy on the acceleration (this is key) to get going again ensuring you keep the rpm's at around 1100-1300, and during the 34-38 mph shiftpoint it would feel like running over a rumble strip.
I also tried it where I accelerated through the 34-38 mph shift point at around 1800-2000 rpm and it would not do it at all. I know some will say well drive the truck a little harder... and that is fine except when you are in traffic. Also, now with my new tranny it is good at any rpm range. OBTW, my truck was 8/07 Indiana build.

I took delivery of my new truck last Friday and it is exhibiting the rumble strip symptoms. My truck is an 07 DC 4x4 with an 09/07 build date. The vibration only happens on occasion and is not very noticable as it only lasts for about a second. My question is should I take it back to the dealer and address it with the svc. dept. with whom I have had less than satisfactory service from in the past or contct Toyota directly to let them know the issue I am having. Any input would be appreciated.
Bowhntr,
I suggest you attempt to duplicate the rumble using PVTUSMC81's guidance. Once you confirm for yourself that you have recurring rumble.... Call service manager at your local dealer directly. If he/she doesn't tell you to bring it in for a check immediately document your call and follow up with a call to Toyota National Customer Relations. There is an (800) number in your owners manual. The problem is well documented and you shouldn't get a run around. Definetely need to take it in.
If information shared on this site is accurate, Toyota has reengineered new manufacture transmissions post 1 Oct. So you should be able to get a new one the work right.
Yea whats he said is true...take it in they should confirm that they no about the problem right away...i see you are in pa as well....seems the 4 of us here are all on the east coast...va, pa, nc......keep us informed of what you have come up with....when i took mine down the other day they even asked me what forum i was talking to everyone on and they knew tundrasolutions from another customer lately soo looks like we are gettin some attention on here LOL....
My main concern is dealing with a service dept. where I have had less than stellar service in the past. We are talking about major surgery on a brand new $35,000 truck, it scares me just thinking about it! I wonder if Toyota will issue a recall campaign if this issue is as widespread as it seems to be? Should I make my issue known to them and then take the wait and see approach. I would rather not have my drivetrain torn apart if the "issue" is later determined to be remedied in a less invasive fashion. This whole thing has me pretty upset as I assume it has everyone else.
Ok, my rumble strip experience is following in line with the others. The tech spoke to the big wigs at Toyota, told him to disconnect the brake light so that the torque converter would not engage and see if the problem went away. It did, so apparently it is a torque converter issue. Toyota told them to replace my tranny. The issue now is that they do not have a "new tranny part number so they are not available. I'm told there is a remanufactured one here in Portland they could put in right away. I've decided against it, partly due to recommendation of the tech who is a cool guy, and will fight Toyota for a new tranny off the line. If what everyone is saying is true that the tranny's have been modified post Oct. 1, why would I want a remanufactured unit put in my truck that may experience the same problem?
Bwalky,
I think there may have been some confusion at your dealer concerning how the Brake light switch functions in association with the TC. Probably doesn't matter at this point if they are willing to put in a new Tranny.
On the other hand, having conferred with many posters on this site and talked to dealer SM, Area Rp and National Customer relations.... Reman is a program Toyota uses to replace tranny's. We have a long list of Toyota representatives who claim, verify, insist that no rebuilt 6 speed transmissions exist for the 07 Tundra. Toyota has not yet begun the remanufacture of the faulty units which is where they would come from.
So far all of us on this site who have had their Trans. successfully replaced have service paperwork that says REMAN ATM. Dealers claim these are all brand spankin new transmissions.
Indeed, we have seen a number of posts claiming Toyota found the problem with the rumble and has already completed redesign, and implemented changes for Oct.1 forward manufacturing. This remains to be seen as I don't think any of us on here can verify that claim for sure.
I can say that I have personnally been in contact with Toyota's Customer Relations in Ca. His name is Salvador. I would be glad to provide his number. Anyway, he basically told me the same thing I have just stated herein. Toyota is not going to tell any of us what the specific problem was or is. Nor will they share with us what the engineering fix is or was. He did tell me that if a know problem with a transmission crops up and is verifiable and it affects other units. All existing units are pulled from stock and basically black listed so they can't be put into another vehicle ... Period.
Toyota does not deplete existing stock of these items and risk having a failure. Just one more reason I have owned nothing but Toyota since 1992.
Hope this post helps some make decision to move forward and get their rumble taken care of.
I get mine back tomorrow and am expecting good things. In the mean time have insisted that Toyota provide me with fact certain that my new tranny is post Oct. 1 mfg including design improvement. We'll see.
o.k. guys how rough/violent is the rumble?i think i may have it but it might just be my b.f. goodrich tires and the trd shocks?can you feel it through the steering wheel?does it shake bad.or can you basicly here it and it sounds like little rumble strips or maybe buckshot mudders?mine isn't bad enough that a service guy could tell i don't think.on a scale of 1-10 how bad?

I used to live there in Salem, did you go to capital toyota? I would take the time to head up to wilsonville toy and talk to them. They are very customer oriented and will take great care of you.
Good luck with your tranny.

From what I have read...it varies. Mine is pretty light...think running over a very run down, worn out rumble strip. Lasts for about 1/2 to 3/4 of a second. Can kinda hear/feel it...though not loudly. Sorry....kinda hard to explain. The first few times it happened with the tech in the car, they did not notice it. I had to point it out ....then they got it. I was driving though...and I think having your hands on the wheel helps you "feel" it.

The general concensus is about the friction surface finish being dimpled on the converter lockup clutch due to a manufacturing defect. This is also the case with the one way clutch sprague in the convertor. I took a look at a torque converter which was taken out of a defective trans at the dealer and was not impressed with what I saw. There are spots on the front turbine side of the converter that are spot welded and could have possibly re-heat treated the front friction surface of the lockup clutch. I'm not saying I know as much as a toyota design engineer, but in comparison to other transmissions I've worked on (ford had a converter problem in their AXOD trans like this) with this kind of problem, it would be a definitive explanation. Apparently our torque converters are manufactured by aisin-warner in the US.

I am waiting for the dealers out here in Oregon get up to speed. I have contacted two dealers and neither has heard of this problem.
This is so true. The dealers out here are a year behind everyone else. I think it might be due to lack of volume in sales. The two dealers I now frequent are Gladstone Toyota and Ron Tonkin Toyota - the latter one having the better, more experienced service department. Once the official TSB on this was released, techs were more in tune to acknowledging this problem. When I experienced some shudder from my transmission the first time, I knew darn well it was a problem with the torque converter and couldn't convince any of the guys out here until the TSB popped up through toyota themselves.

I have a vibration occasionally at idle in gear. Feels like rumble strip but I am completely stopped. I have never had the rumble strip vibration while moving though, has anyone else had a similar issue?

I actually bought the truck at Bend Toyota and have had it evaluated at Beaverton Toyota. The Beaverton mechanic is a good guy and has recommended I push for a new tranny, not a remanufactured one that may have the same issue. I really like the people in Bend and appear to be busting their butts to get through the upper Toyota bureaucracy to get me fixed up. I'm cosidering having the work done in Bend because they deal with many more 4 wheel drive vehicles than this side of the mountains. Still waiting to hear what Toyota will do now that I have a case number through the customer care line.
I've got it also.
Mine was built in August.
I thought it was part of the break-in cycle.
It was bugging me so much I made an appointment today (2 weeks out) without reading this forum.
The guy looked up my VIN and NO TSB for mine.
He stated that fact with an intonation like "we cant help you unless there is a TSB on your VIN."
Going to make a few phonecalls tomorrow to customer service line.
I love the truck otherwise.
On a positive note, my dealer sent me a loaf of bread by mail. Nice touch , or a bad cliche if this goes poorly.
