Have a Tundra with 2500 miles. My garage is under my house (live on a lake so it is bermed for the lake) When I first start to go up my driveway (approx. 35 degree ramp up to the street) and the truck is cold, sometimes the transmission will "slip" and bang into gear. After taking to a dealership they can't make it do it (so they say) I left it for a week. Still does it every now and then but I am concerned that I will have problems after the 60,000mi. warranty. Asked them for an extended warranty,they (Toyota rep.) said no. I am now going to arbitration where I am sure they will say no, then to court. Love the truck but something is wrong. Even my wife felt the bang and said none of our other cars do that. By the way, they put a new torque converter in it to no avail. Why would they do that if they couldn't find anything wrong. ANY HELP WOULD BE GREATLY APPRECIATED!!!!!

Update to my engine knock...toyota tech had the dealer pull the engine so they can change the lower end bearings. I am getting my info from the customer relations manager so there could very well be some confusion on what toyota wants them to do and what he is telling me. From what is sounds like the crankshaft bearings is what their targeting. The service manager is fighting to get them to send them another shortblock. I don't blame him for wanting the short block, a lot of labor going into changing the bearings and it not fix the problem. Truck is sitting in a stall w/o an engine...I consider it great progress...this would have never happened with Ford or Dodge, they just ignore problems until you go away.

i have the early 07' (jan 07' production) tundra limited 4x4 dc w/ the 5.7 and the 6spd, which had a low speed and high rpm shudder in the trans. The dealer just replaced the torque converter which solved that issue completely. They told me that my truck was one of the first 700 to roll off the line and all of them with the 6spd possibly had defective converters (so toyota rep says). At least i can say i did get 36K out of the trans before it started its bad shudder, but it did take two trips to the dealer to solve, which was pretty annoying.
No problems with the 5.7 motor at all though. It is noisy when cold, but if i let it warm up for a minute or two its fine, even when its in the teens. (mobil-1 0w does quite it down more)
I have 39K on it now and just noticed a wierd noise and feel coming from the front end. When driving around 30-35 mph on a slightly curvy road, i can hear a humming noise and feel some kind of grinding coming through the steering wheel. It almost feels like the front axle is binding up, as if i had it in 4wd on dry pavement and tried to turn hard (which i've never done in this truck). It really has me concerned now because i'm over 36K w/o an extended warranty. (i love that feeling)
Has anyone had an issue with the front end in the 4x4 models? My truck is driven 70/30 highway/city...

Sitting at a stop light, the engine revs from 5-600 rpm to 7-900 rpms. It fights against the brakes. Also, when coasting at about 1000 rpm and coming down, the vehicle will lunge up to 1200-1400 rpm. THis has happened 3 different days, I have 6,000 miles on it.

Not my windshield but barley bumped my taillight and it broke. They are really thin plastic. Be careful....I also got rear ended and needed 4k in repairsmnew bumber,a few dents,new trailer hitch. So they gave my an 08 Silvarado that was way more comfortable!! (not as fast though!)

A couple of possibilities . . .
First, your A/C might be cycling on and off, which may slightly raise the idle to compensate. Both of my cars idle slightly higher when the A/C compressor is on.
Second, many vehicles have grade logic and shift to a higher gear when you tap the brake and are slowing down. Even if it doesn't, the RPMs are going to rise slightly when the vehicle shifts as it slows.
This behavior could be entirely normal.

I just purchased this truck today and on the way home, the ride felt a little bumpy, is that normal?

Mine is similar, it seems like the system that is designed to help slow the truck down actually pushes it forward in a surge sometimes. I have found that my truck stops quicker if I push the tranny into Neutral during coast down.
Right now my truck is getting a new engine in it for a knock. The truck I am driving is a 4.7 Ltr and it is smooth as a baby's butt...if I didn't need the 5.7 to pull my camper I would be very upset when comparing the two engines. Trust me though, the 4.7 cannot compare to the 5.7 in horsepower.

I have a similar "knock" that I posted about on the "mud" blog. Seemes pretty noisey on cool/cold mornings, and after about 5-10 minutes goes away. Sounds like a bearing knock to me. Took it to the dealer who said was normal (injector noise) and sent me on my way.
I have seen many reports of this noise, and have a couple of friends that have these and say they have no noise. I guess I will have to wait and see, but want to take it in a few times in case it does create an issue down the road, I will have some recourse (hopefully). I told my dealer (American in Albuquerque) that some were reporting problems and they kind of shrugged it off. I would like to point them to a dearler that is actually pulling an engine due to the problem.
Where are you and what dealer has your truck?
