About, or after 2000, these was a divergence in the firmware control for Toyota and Lexus RWD & R/AWD vehicles vs FWD & F/AWD vehicles. Because loss of traction on the driven wheels of a FWD is such a more serious, potentially more serious, matter than loss of traction on the driven wheels of a RWD, the detrottling of FWD vehicles is virtually simultaneous with the detection of wheelspin/slip.
On a RWD dethrottling is often delayed a few hundred milliseconds after wheelspin/slip is detected and braking is applied.

But the biggest mistake was actually yours, not having tire chains installed on the rear when clearly that was what was required.
Chains? Well I guess a snow cat would have been even better. If you had read my post, or comprehended it, you would know that 99.9% of the roads were clear and it was 40+ degrees. Absolutely no indication that chains would be required.
The isolated icy stretch was only about a quarter mile long that I came upon quite unexpectedly. Even if I had chains with me, which I didn't, it would have been impossibly dangerous to stop on this very narrow road and attempt to install them.
If there had been any indication of bad roads I would simply have taken my SUV. Unfortunately there are some circumstances that you just can't foresee.

Ncee.... this may not apply to you but you mentioned no sun roof rattle, but you did notice a rattle in the dash. Does it sound like it's coming from the right side ( passenger ) side of the dash? That's what I first heard and thought the rattle was coming from the dash. After I got on the internet and started researching the rattle issues with the avalon, I found a post that someone left saying they heard a rattle on the right side of the dash ( or at least thought that was where the rattle was ) but actually it was from the sun roof. Well, the next time I heard the "dash" area rattle, I opened the visor on the sun roof and pressed lightly against the glass... sure enough, the rattle I thought I heard n the dash, stopped everytime I pressed against the sun roof... I suspect the reason it sounded like it was coming from the dash area is becuase the rattle sound was traveling down the A-pillars into the dash compartment. In any event that's how I discovered it was my sunroof. Dealer said something about sending it to a trim shop where they would have to drop the headliner but since the rattle goes away as soon as the car interior warms from the heater, I elected not to have it worked on. To the gentleman that said they lived in Oklahoma and doubted it would get cold enough for the rattle, well, I live in Louisiana and it gets cold enough here for the rattle so i'm sure it will be cold enough where you live. However since you have an 08 or 09, Toyota may have corrected the problem in the newer models... hope so for your sake... enjoy your Avy... they're very good cars, but hey, I've never owned a car that was perfect.

Right side and sometimes center. I will check the sunroof the next time it happens and see if it goes away. It will be nice to at least know what and where it's coming from.

Ye I've read/heard some "interesting" stories on the bad side of TC.
I've never had TC (I'm originally from South Africa) and heck, I haven't even had ABS before coming to the US.
We had to learn all the manual ways of pumping the brake and so forth (which I truly believe makes one a better driver than throwing them in something that "thinks" for you at 16)
Anyhow, the 07 XLS I got my grubby paws on has no TC, I've had a few wheel spins on icy roads and the car has had that situation where it wants to pull to the side as traction is lost on one wheel, but so far I've found the car to be very forgiving of getting into situations and pretty easy to get the Avalon out of them all.
So far so good my side *knock wood* 
I've never had much experience in RWD though other than a Dodge Charger rental (which I loved the feel of, thing felt like a 10 ton tank sunk in the ground, felt VERY stable), I don't know that I personally would change to RWD just due to my inexperience with it in a climate that gets snow/ice.
Cheers guys

Thank you for that post.
I too have a 07 XLS and have also noticed a rattle at time that from your description sounds very much like mine, I have never suspected the sun roof though.
Next time I hear this I'll put pressure on it and see if it also is coming from there.
Thanks again
Sheldon

Yes, I think you are right about learning to drive without tc. It should make you a better driver. I'll know to disengage tc next time in get in a fix like that ! The Avalon is a great car, enjoy, and welcome to the good ol' U.S.A. !

Visited my local dealer today & the sales Mgr. said there will be an all new 2010 Avalon in the showrooms
Sept/Oct of this year. No details on the car, yet; but he said his onfo is straight from Toyota USA.

On this board see post #23 dated Nov 16th... Japan always knows first as it's the home office where all major decisions are made. Only after the big decisions do the area people, like Toyota USA, get involved. My last discussion on this subject with the dealership connection did not provide anything new, just confirmed a different car...again. All spy pics welcome!
