    Obviously you do not carry a purse and if you did, you would know the designs of them. Not only my purse, but my kids book bags which also have ZIPPERS on them! My laptop bag which has ZIPPERS on them. Get it now!!

    My door jamb gets dinged every time I unbuckle my seat belt, dozens of those dings quite visible after 10 years of ownership. If it bothered me I would be a LOT more careful with the way I unbuckle the belt.

    You could do the same thing, be more careful, with your zippers, etc.

    Modern day 6(10) speed automatic tranmissions, 6 "hard" gear ratios with the Torque converter in the loop, and at least 4 "soft" gear ratios using the TC locking clutch to bypass the "lossy" torque converter.

    Those "soft" ratios are used for simply cruising along with light loads on the engine. But anytime a level of acceleration, even minor level, is involved, or extra engine loading, traveling uphill, towing, etc, the TC MUST be in the loop. Plus, if you should step on the brake pedal just enough to turn on the brake lights, the transmission will, MUST, unlock the TC.

    10 gears to chose from in order to keep the engine RPM at the most optimal level for current speed/roadbed/travel conditions.

    Like to try that, always being in the most FE correct gear ratio, with a 1o speed manual transmission..?

    I thought not.

    "..it will downshift to slow you down.."

    No, YOU are the base cause of those downshifts.

    Look at the fact, in the Prius, that the regenerative braking system is used to simulate engine compression braking during coastdown periods. Basically putting fuel BACK into the "tank" anytime the driver has no pressure on the gas pedal.

    Would the Prius be just as fuel efficient absent this coastdown hybrid battery charging technique...?

    NOT..!

    Only if the driver used coastdown periods, "free-wheeling" coastdown techniques, highly judiously, focussing CONSTANT attention to the matter.

    Your Camry uses the same technique, basically.

    Doing coastdown periods the engine is COMPLETELY starved of fuel, the injectors are disabled. But now, to keep the engine RPM from dropping too low and stalling, new downspeed gear ratios must be selected, again and again, as roadspeed declines. Once roadspeed has declined to the point wherein the engine RPM cannot be held above "stall" the idle level fuel flow is restored and the transmission is quickly upshifted to remove the engine load.

    If now the coastdown period continues to a full stop only then will the transmission shift into first gear.

    Whole lotta SHIFTING going on.

    Be aware that the above is true, or soon will be, for almost all modern day passenger cars.

    "..cooling power is marginal at best.."

    I'm betting otherwise.

    Have you previously owned a car with the NipponDenso, Denso US, automatic climate control system..? These systems are designed to "moderate" the level of coolness of the outlet airflow once the cabin temperature is near the temperature setpoint. If you want to get an idea of how adequate the base cooling level is then turn it to recirculate, MAX cooling, and lower the blower speed below midpoint.

    On the hand if I am wrong (not likely) you can always go to Home Depot and buy a manual water flow shutoff valve to install in the engine coolant hose to the heater core. Not a bad idea in any case since that way the A/C will not be being used to COOL the engine water jacket....improved FE.
  • As a person that has own over 30 vehicles in my life, and has had a hand in fixing many of them, I can tell you that this Camry is unusual. You may justify the engineering of modern day 6 speed transmission as a compromise for power vs efficiency; however, the Camry doesn't do that smoothly at all. So much so, sometimes it feels as I am driving a stick shift. There is no excuse for a design like this. In fact, other Toyota models (Corolla and Tacoma) do not shift anything like the Camry and the Corolla being a 6 speed as well.

    As far as the cooling, we live in South Florida where it is 90+ degrees and 100% humidity sometimes, and the Camry can barely keep up. In fact, if you are seating in the back seat you are sweating for the most part even at full blast. I finally decided to tint the windows to help the cooling a bit,

    Just a side note to those that respond in defense of Toyota. I have owned 6 Toyotas prior to my Camry. It used to be that if you bought a Toyota, you were going to be satisfied. This Camry is designed poorly and I can't vouch for the sudden acceleration issues that dominated the news a few years ago with this car and, at that time, I thought people were making up the problem. However, after owning this Camry, I think maybe there was truth with that problem. All in all, I don't plan to keep this car.

    2010 Camry (same as 2011) at 95F and very humid day here (80%) has no problem keeping us cool, back or front.

    and the Corolla being a 6 speed as well.

    Corolla has a 4 speed automatic (older design, probably at least 10-15 years old). Corolla still has great efficiency though, and turns low rpms at highway speeds. Don't know about Tacoma.

    Some people complain about the Camry 6 Auto Transmission, but most don't . I have seen some others complain about the shifting of the automatic, but most think it is fine. I have driven a Camry 6 Speed auto for a few days, and found it to be fine - before I drove it, I knew about some complaints about it, but I honestly had no complaints with it. Also, very quiet at speed, just like most professional reviewers say.

    I'd take back to dealer and have them check it out, maybe drive another Camry to compare.

    I first encountered one of these new 6(10) speed transaxles, Chrysler Sebring Conv rental, while on vacation a number of years ago. Reasonably flat terrain yet the tranny just simply could not find, settle into a gear. I found it best to drive it in CC.

    I'm hoping that by the time I need to buy my next daily driver that actual CVT's will be available.

    I suspect the hard shifting is the result of the shiftiness. If so much shifting is expected throughout the vehicle's useful life then the shifting must be quick, solid, and firm, no slippage, frictional surface wear, allowed to "ease" into the next gear.

    In my experience even an LS400's climate control system, even with dark window tint, cannot provide a good level of cooling for rear seat passengers on a HOT day in Tucson.

    The ducting to the rear simply does not have enough volume, CSA, to move enough moderately cooled airflow. But there are a couple of things that will be helpful...

    To cool, COOLDOWN, the entire cabin most quickly:

    First and foremost, DO NOT allow the system to go into recirculate initially. It is best to leave the system in "fresh" mode initially thereby FORCING the SUPERHEATED atmosphere out of the cabin. As most owner manuals suggest it also helps to lower the rear windows for a few miles to help with this matter.

    Now, after the cabin's HOT atmosphere is purged, move the mode to recirculate, bypass the system's MODERATED cooling mode via using MAX cooling, manually close the front outside, nearest the side windows, airflow ducts ("force" more cooling airflow to the rear seats), and now use the blower speed to optimize the overall cooling level.

    In my '92 LS400 I find that if I use the above procedure for quick cabin cooldown on a HOT day then within 10 or 15 minutes (interior surfaces also cooled) I can put the air temperature control aspect back to auto and basically ignore the system operation thereafter.

    Oh, one nice aspect of the LS400 is that I can open the engine hood, disconnect the servomotor drive from the heater core engine coolant/water flow control valve, and then tie the water valve full closed. Basically making the reheat/remix blend door movement, system airflow temperature moderation control, non-functional.

    I have no idea, other than the total idiocy of NipponDenso, Denso US, engineering team, why the design of these automatic climate control systems has gone so far awry from reasonable, sensible.
  • Use your brake to hold car, DO NOT hold it with trans, or you will overheat it.

    You can use left foot on steep incline to hold brake and right to accelerate.

    I'm having same issues with my 2011 Camry. I'm in with you guys. Let me know when you are ready.

    If you don't know the procedure for engaging, activating the "hill-hold" feature you may be intermittently engaging it, or not, resulting in the roll-back randomness.

    Best to reseach this in your owners manual but I beleive it needs a sharp "stab" of the brake pedal, and then release. "Stab": higher momentary brake pressure beyond just the level needed to hold the car on the incline.

    Interesting. I didn't know the car had this function. I'll have to try that. Thanks.

    I am considering the 2011 SE and am pretty dismayed to hear about these issues with the 6 speed auto. Does anyone think that shifting manually in slower speed around town traffic will alleviate some of the problems or symptom related to this transmission?
  • kbetts1kbetts1 Posts: 36
    Manual shifting helps a little but overall it's just a weak transmission system. It feels as if they got the gear ratios in the transaxle wrong and the engine is pulling too high a gear.

    Whatever the case, for a high percentage of drivers it's bad enough for them to wish they bought something else. After six months and 15,000 miles I'm one of the people who wishes I'd bought something else.

    I also read these stories before I bought my Camry, and I am not sorry I bought it. I have used the S shift option on the AT, and I found it fun to rip around curvy back roads, but I'm happy with the AT. It knows what to do to keep the power band where it should, and I have fun just letting it do its own thing when I'm flying around the back roads. I thought maybe having bought a manual transmission would have avoided this sometimes rough shifting AT issue, but I'm ok with it the way it is. I don't think something has to be perfect to be "good enough". I got a great deal on my Camry, and expect it to last, so I'm happy. I still look forward to driving it, after 5,000 miles. Was not able to say that for my 2010 Prius III after 4,000 miles. I had to drive to an airport two hours away, in the early morning, in the dark, in the cold, and I dreaded it! The thing was so light, and hollow feeling. I didn't feel secure in it. The Camry is much more solid, and stable feeling. And the motor is more powerful. I guess it's just a matter of finding what you like. I'm happy with my Camry. I feel very safe, and secure, and comfortable driving it on a long trip. My Camry seems to like being driven a little bit harder. The AT seems to like that better than being babied; it'll lug the engine if I do that. Also, I got 32mpg the first tankful of gas, 30mpg second tank, and 26-27 thereafter, although I have been using the AC since then. I did take it to the dealer for the 5,000 mile service, and got 30 mpg after that. Now down to 26. I wonder if they put something in the gas tank to make it get better milage? I'm alright with 26-27, but would like 30-32 better.

    I wish I came across this site before I bought my camry LE 2011. This is my fourth new car. After just weeks, I absolutely hated this car. It is ridiculous that there are so many problems. The biggest annoyance for me is that it overturns whenever I make left turn. It is really close to impossible to park straight in a parking lot, because it always overturns and the wheel does not come back even when it is released. If I make a left turn and release the wheel, the car keeps going to the left in circles. The back window defrosting is awful. I can see that it would be a big problem in winter. There is a trange loud noice coming out under the hood. The door opens too wide easily, making me nervous at parking lots. I also do not like the key. I accidently openned the truck twice when I turned off the car. It is a poorly designed car. I do not understand why so many of them on the road. That is the fact that influenced my buying decision.
  • Yes, I find the tranny a little odd and sometimes annoying (only driven 1000miles), but if this car gets 100-200K miles out of it, which C'mon all you Camry owners, it will, it was worth the purchase. I traded in a 2010 Nissan Altima 4cyl CVT, and have NO regrets, the CVT was way worse than the 6spd camry, I am more comfortable knowing I have a quiet, smooth, vanilla toyota. :)
  • My family has owned 5 Camry's, a '92, '93, '97, '05, and my '10. Only my '10 suffers from the jerky transmission issue described throughout this thread. It is so bad that I am seriously considering taking the huge hit to trade it in and get a real car. I live and work downtown, so all of my driving is city, and this constant shifting <10 mph is making me incredibly frustrated.

    Has anyone made progress with lawyers/getting Toyota to actually care about this yet? I see posts back over a year, someone must have heard something meaningful back. The dealers here in CO "haven't heard" of this issue and want $100 each time I bring it in to tell me that I'm crazy.

    Mine does the same thing on occasion. VERY annoying.

    During your next trip, move the transmission "+" "-" selector to where a "3" appears near the odometer while in stop and go traffic below 35mph. Selecting 3rd gear will keep the transmission from going to too high of gear.

    When traffic speeds up go back to "D" or normal. I did this and it really helped with the transmission jerking. The same thing might re-train yours to start behaving correctly.

    Drove to NYC, and back, tankful of gas, 30mpg, very disappointing. Comfortable. My transmission acts the same. I guess Toyota has seen its day, and its sun is setting, as is Honda's. They were always the best cars for me, growing up. Many people my parent's age contiued driving American cars, even when their sun had set. I guess things change, and, unless we change with them, we get this these types of frustrations. I've heard Hyundias, and Kias are good.
