Default 07 Cruise Control

Anybody having problems in the 07 5 Speed A/T cruise control? I have
not driven a car with cruise control before. Is it normal for the car
to shift to lower gear on a slight incline driving at 65-70mph with 4
passengers, 2 adults and 2 kids on board.

Perfectly normal considering the weight concerned....You didn't say if it
was a 6 or a 4 but the weight pulling a hill will engage the downshifting
with cruise on....my 86 camry 4 banger does the same thing but with less
weight involved....don't be concerned, its normal, all things considered.
Enjoy your 07, we sure do.....

Sure, if the incline is such that to maintain the speed you've chosen, it's
necessary to downshift. Remember that the cruise control is programmed to
maintain a speed, and if the higher gear is allowing the car to slow down
going uphill, the control will choose a lower gear to maintain that speed.
Think of it this way....if you had no cruise control, and you keep your foot
on the accelerator going uphill at the same pressure, the car is going to
slow down, because of the hill. So you either have to press further down to
maintain the speed ...or slow down. If you press down, the car will
increase speed by its acceleeration...and/or it may downshift into 3rd to
give enough pep to take you to the top.

I see your point. By the way its a 4 cyl engine. and I really enjoy my
07, Thanks!

I looked on the earlier posts, I saw transmission shifting problems too
(not cruise control though but on A/T slipping). I don't use cruise
control on my everyday driving. I remember the issue when I drove from
LA to San Francisco a couple of months ago during the long weekends.
The transmission would downshift until engine speed would reach
3500-4000. The car did that several times, even at higher speeds of
75-80 mph (of course at higher rpms). I really thought during those
times that I should have gotten the 6 cyl and also not used the cheaper
fuel from COSTCO. My wife was asleep and I knew she felt the engine
roar when the downshift occured.

I want to hear from you guys since I will going back to Toyota for my
first 5,000 mile service. The cruise control was the least used device
on my camry.

have an 06 le 4 and it does the same thing. guess you have to pay for
that 33-34 mph highway some way. i don't hardly ever use the cruise on
my 06 because of this. say if i an driving 75 on the interstate and
going up a grade will let up on the excellator a bit and the car might
slow to 70 or so. then going down might get up to 78. this keeps the
transmission from downshifting. know it might sound funny but don't like
the rpms going to 4000 and above. these camrys are geared high. if you
notice at 64 mph your rpms are just 2000 on the 4cyl, which is really
low. thats why they get way up in the 30s on the road. you can get 500
plus miles on a tank on the road.

Sounds normal. The cruise control system doesn't deal very well on
inclines. It has the tendency to open up the throttle more abruptly
than drivers do and that will lead to down shifts.

Yes, this is in part because the engine doesn't produce enough torque
to haul along even on adult. V6 would have less of this problem. Also
if you were to slowly increase throttle manually there would be less
downshifts than letting cruise control do it.

Mine too. Incline requires more power/torque so it downshifts to
maintain the desired speed.
