If I read these posts right it is my driving style--not giving the car enough gas causing vibration rather than the transmission---I guess the next question is why put in a 5 speed automatic in newer Camrys when the 4 speed automatic in my former 02 Camry had worked just fine--same gas mileage, better smoother shifting etc.??? Thanks for your input..

Just keep giving the car gas from what you say will help--any comment on my post of 2-16 on why go to a 5 speed auto from a 4 speed when the 4 speed was just fine--now I see some cars are 6 speed automatics--just more stuff to go bad????? I appreciate reading all your responses--------------

With the advent of CVT's Continously Variable Transmissions, it has become obvious that more gear ratios can/should mean improved FE. The new 6 speeds often have 8 or even 90 forward gear ratios using the lockup clutch in other than OD.
 
With a "strong" V6 it is not at all unusual these days to have both of the top two gears be OD ratios.
 
The idea, for best FE, is to keep the engine at the lowest possible RPM at which it can just barely produce enough power to move the car along smoothly at any speed you happen to want to "cruise".
 
On the other hand if you choose to accelerate "briskly" then the transmission needs to be able to put you well up into the engine's torque range, again, at any speed.

Another question--What advantage is the DRIVE BY WIRE system on the 08 Camry compared to the 02 Camry--many thanks-----

The '02 Camry also had drive-by-wire, as do most cars nowadays. This means the throttle is fully electronic, with no cables or mechanical linkages to bind or break.
 
I have to agree with you to a certain extent about the 4-speed vs. 5-speed automatics, because I have one of each ('04 and '05, both 4-cylinders). The 5-speed can get annoying in city driving, with too-early upshifts into 5th in which the engine appears to "bog down" or lug. If I'm going 40 mph or below, and there are inclines, I will often just lock out 5th. On my 4-speed, I don't have to do this.
 
Interestingly, the 4-speed consistently gets better mpg on long highway trips than the 5-speed -- this makes no sense to me, but that's the way it is.

DBW eliminates the idle control valve and bypass port, the cruise control servo, and allows dethrotting with TC, Traction Control, rather than fuel starvation via injectors.
 
The latest thing seems to be the engine/transaxle ECU "watching" the rate at which you release the gas pedal in order to determine, hopefully, your intent. Fast release, no shift (remain in low(er) gear ratio for engine compression braking), slow release, upshift to enter cruise mode.

Good post---I guess my concern is if you change something make sure it is much better--not just to make a change--do you think the CVT is the transmission of the future? I drove one--very smooth--any downside????Also on various message boards on vehicles it appears many people have negative comments on the Camry transmission shifting etc. Just hope it does not affect resale value in the future. We will see what the April issue of Consumer Report says of the 07-08.

Thanks. It looks like the CVT is falling out of favor for many manufacturers, except for Nissan, which is using CVTs in many of its models, and of course, for gas-electric hybrids like the Toyota Prius and Camry Hybrid.
 
More gears in theory will give you better fuel economy. But one problem I've read with CVTs is that they tend to make the engine stay at high revs in many situations, which makes them objectionable to some people because of more noise.
 
The Camry with the numerous transmission complaints is the 6-speed unit in the Camry V6. The 5-speed auto in the 4-cylinder model has been much less problematic, and I'm not aware of any significant complaints with the CVT in either the Prius or Camry Hybrid.

Just Bought an '08 Camry... by valentinecamry

...2 days ago. Any suggestions...tips...gulp...warnings? My wife and I just replaced our 10 year old Accord (without power-anything) with the Camry...so we are a little late on the technology other folks take for granted...
 
So far, it is as good as what people tell us about Camry's...although my family bought a lemon of a Camry about 15 years ago and since then, they have became a Honda family...we're finally breaking the mold...
 
Originally, we were crazy enough to think about getting the Scion XB..but rationality got the better of us...
