    I've got 5,000 miles on my '09 Access 4 banger auto and was rolling along at 70mph at about 2200rpm on cruise control and headed up a small hill into a 40mph wind. Cruise kicked out the overdrive, then went to 3rd,...... and then went to second gear at 5500 rpm! Suprised or scared the crap out of me! Is this normal? After that, I manually put it in third on the uphills.

    The speed falls off so quickly that the cruise control continues to downshift all the way down to second to get it back. I've learned to manually shift it into trrid when I hear it start to downshift. That seems to keep it from downshifting into second. I upshift at the top of the hill or bridge back into overdrive.

    I have to stop using CC whenever a hill is coming up. The CC wants to stay exactly at whatever I set it at. For example if I set the CC at 65 and a hill is coming it will give a little more gas but if it is still at 63 or 64 it will just floor the pedal until 65 is reached.

    CC will save you gas on flat long stretches but not on hills. When I drive on a hill my speed may drop a few MPH and that is fine. I don't need it to stay at exactly 65, so, to avoid the auto trans downshifting I allow the vehicle to slow a few MPH and I keep the gas pedal at the same spot.

    All cars and trucks I have driven have been this way.

    Your CC will accellerate hard when going up a hill to keep the set speed. The vehicle is not a human and does not the sense of touch. All it knows is that you told it to go a certain speed and the computers make sure you maintian that speed. Very normal operation for the CC. If you are not used it, it will get your attention.

    I have 09 AC manual trans so dont know about the auto, but...
    In my wifes car we can turn off the 4th gear OD when in cruise and living in denver with the mountains all around it has become common for us to just lock the tans out of 4th untill it flattens out a bit.

    On the other hand, when I am driving the car I will sort of use the 4th gear OFF button as a shifter, when I see the hill coming up I click out of 4th, the trans goes to third, momentum is conserved (to a certain point) and at the crest of the hill click back into 4th for the down hill or flat.

    It all comes with knowing how the car will react on hills of differant grades.

    I have a Tacoma Prerunner and tow a 17' fiberglass camper about 2500 lbs and am wondering if the cruise control can be adjusted. I tow at abut 58-60 mph and notice that even on slight grades the transmisson will downshift. It seems too sensitive and sometimes a strong headwind will cause it to downshift.

    I currently just pull the control to coast and use the foot feed till the road levels and then re-engage.

    I would really like to have it adjusted to be less sensitive.

    The Tacoma really pulls the camper beautifully otherwise.
