It doesn't really shudder
I know that shifting into D when the car is rolling back at 1 mph doesn't have any adverse affect on the tranny.
 
I am just trying to help the person diagnose their problem

YOU are NOT alone!
I just bought a 2008 Sport trim ( with leather and 3rd seat) a month ago and have the same problem. Vehicle vibrates ( fine vibration but annoying enough to notice/ it wasn't there when i first brought it home) while driving at sporadic times. Usually it is when accelerating but most often at 50 mph +. . It ALSO started vibrating ( sporadically) on START UP in the mornings, (after a week of ownership). This vibration is more pronounced than the one during movement-- it is a dull humming vibration as soon as you turn the key. I don't even put my foot on the accelerator.
 I am trying to decide whether or not to take it in to our dealer. I am very dissapointed with that prospect because I have heard so many bad things about Toyota's DECLINE in the service world. I spoke to my car rep. about it before I purchased and he said that they are making major changes and I should not have any problems with service- Toyota is working fast to rectify the issue because they have been taking huge losses with that issue- customers have gone to Honda. I hope he is not wrong. I did not think I'd have these problems so early.
What makes it hard to assess is that it is sporadic. It does not do this every morning.
 Another issue that I am starting to notice ...The ride used to be quiet but there are times when it sounds like there someone left the back window down.
 
Has anyone noticed 2-3 second acceleration lag when accelerating? It just started doing this.

We have only had our 08 Limited for a couple of weeks, but I too noticed a vibration coming through the steering wheel. Occurred around 100 kph and above to about 120 kph. Once again vibration may be not the most accurate way of describing the condition. More of a lower pulsating kind of high frequency shudder. I had the vehicle into the shop for another issue and informed them about the shudder. They reported back that a tire was slightly out of balance. They corrected the balancing issue and rotated the tires. I really don't think rotating the tires should have been necessary. They may have done that to make sure the problem front tire was moved back temporarily. Can't wait to it's rotated up front again. I won't be surprise if the shudder comes back. Just out of curiosity, what tires do you have on your Sport? I have the Toyo "Open Country" A20s and I don't think they are going to last very long.
 
Also noticed that on cooler mornings, as reported by other owners, the vehicle runs surprisingly rough when it is first started.
 
I have not noticed any acceleration lag. I did notice it on the previous incarnation of Highlander. In 2005 I test drove a Highlander and the lag was very noticeable. For that reason, I did not get a Highlander. Instead went to a Pacifica. So far no acceleration lag in the 08 Highlander but there are some other handling issues that are disappointing compared to the Pacifica.

Did you ever find out what was wrong with your Highlander? We just bought a 2009 and it is doing the same thing you described.

Either its not doing it anymore or I just don't notice it anymore. You'll be very happy with your purchase.

I bought a 2009 this weekend. I have been experiencing the pulsations/vibrations at ~45-50 MPH. Very similar to what has been described here - cannot reproduce, happens when I am cruising and stop if I accelerate of decelerate.
 
While picking the car, the dealer kept telling me not to use cruise control for the first 500 miles - not sure if this is related. Will check with the dealer today.

Sounds like we are having the same exact problem. We are pretty certain it is the transmission. Let me know what your dealer says. Ours is clueless since they cannot duplicate the problem.

You are not supposed to use cruise control because you are supposed to vary engine speed to provide proper engine breakin period, and is stated in owner's manual.

We have not been using the cruise control. We plan to take ours back to the shop tomorrow for the second time. It appears this is pretty common for highlanders but it is too bad they cannot pinoint the cause. I have done some research and found that it can be caused by a Mass Air? sensor or water in the transmission.

I just bought a 2009 HL. The car also does what everybody is describing here. Dealership is clueless. It seems that only people with brand new vehicles are describing this problem. I wonder if it goes away as the vehicle breaks in. Ours is not as bad as when whe bought it (245 miles now). It seems like the transmission likes to stay in one gear too high.
