I have read that all of this is normal with the new automatics by many (all) car makers. Just do a little more searching here. The "lurch" forward while braking is not an acceleration problem, but it is the tranny downshifting.
 
Rollback on a hill? Again, most (all?) new automatics do this. Have you ever driven a manual? Same procedure applies. Get off the brake and on the gas quick, or set parking brake. Or like I do with my manual transmission, use your foot on both brake & gas at the same time, so there is no lag between getting off the brake and on the gas. But since you have automatic, you could just use your left foot on brake when on a steep hill.
 
I don't think you have any problems. However, I will say I am glad I have my 2010 Camry with a stick shift!

The "sling-shot effect", or the feeling of being bumped lightly from behind, is the result of the transaxle UPSHIFTING once roadspeed declines to the level that the full fuel cut costdown technique must be terminated.
 
As you coast down in speed with the gas pedal fully released this technique inproves FE. The engine is fully STARVED of fuel but kept turning above stall speed via sequentual downshifting of the transaxle as roadspeed declines. Once roadspeed is too low to sustain the engine RPM fuel flow is restored and the transaxle is upshifted to alleviate/reduce the engine load.
 
It's that final upshift that gives you the feeling of slight acceleration or "unbraking".
 
Look at your owners manual for a description of the ESes "hill-hold" technique.
 
With the advent of so much use of the torque converter lockup clutch it has been possible to make the TC much less robust, not as much drive, torque, to the driven wheels with the engine simply idling.
 
The hill-hold technique has now been widely adopted to combat the resulting "roll-backwards" (or forward) issue. On some models hill-hold will only be engaged with a little extra push on the brake pedal after coming to a full stop. Hill-hold uses automatic TC, Traction Control, braking to hold the car in place.
 
As a result, once hill-hold is engaged, you will often experience a slight delay in gas pedal engine response to give the brake system time to release.
 
Then there is the 1-2 second "re-acceleration" downshift delay/hesitation.
 
Remember that final coastdown full fuel cut final upshift...?? If you happen to try to accelerate just as the transaxle begins that upshift sequence then DBW will be used to delay rising engine RPM until both the upshift completes and then the required downshift can be completed.
 
There are quite a few instances wherein this "re-acceleration" issues raises its ugly head, delayed engine response to gas pedal depression.
 
Most because the transaxle has for some reason selected the wrong gear, or is in the process thereof, and now some driver action, "re-acceleration, say, requires the use of DBW to delay the application of engine torque until the proper, "newly" proper, gear ratio is estabished.

1. From Park Gear slams into drive with force when foot is on brake
 
2. When taking off faster, shifting up seems smooth, but not always
 
3. When slowing down with foot off gas, gear downshifts with hard jerk into lower gear about 25 miles per hour.
 
4. When taking off easy, gear slams in hard into second gear shift sometimes.
 
5. Shifting up and down is not always smooth whether vehicle is cold or warmed up.
My car is one year old with less than 10,000 miles and is currently at the dealer. I'm told there is an internal transmission problem and the transmission needs to be dropped and checked out.
has anyone else have this problem?

#292 of 304 AT Problem solved on 2012 model by flbntz

Apr 12, 2012 (5:28 am)

I drove a 2012 Camry L, and the rough shifting a lot of us have complained about on our 2010, and 2011 Camry's is not there. I still like my 2011, though. 16,xxx miles, and no problems. Very comfortable. Maybe get a job 38 minutes away, not worried about the commute at all.

Got the job, 30.12 mpg, back, and forth! Think part of the problem I was getting with my last job, and mpg was that the speed limit was 65 up and down the 15 miles of highway I was traveling everyday, back, and forth to work, and now it's 55. Also, a longer commute, and longer days mean less city driving. Whatever is doing it, I'm liking it. Plus, this car should hold up to high miles. Figure I'll be doing about 20,000 per year, unless I move closer. I like my Camry.

I have a 2011 camry . My complaint is the hard shifting in between gears.Hot or cold the tranny shifts hard as it drops in. The dealer said its normal/ a natural computer problem. Unless alot of peole complain they will not address it. He agreed when we drove it but said the computer giving the signals to shift, down shift etc.. is not as fluid as it could be....I would not buy this car. I have 4 toyotas.

Well my 2011 with the "normal hard shifting problem" left me stranded on the interstate last night. This past week I noticed the engine almost dying and then revving back up. I thought maybe bad gas? no other problems till last night. Everything fine on drive to restuarant. When we got in the car check engine light on, ABS light on and the transmission would not shift out of 2nd gear. Read book and it says make sure gas tank is full??? Not sure what that has to do with it but filled the tank. ABS light went off but car would still not shift out of 2nd gear. Called Triple A and had it towed 75 miles to the nearest toyoto dealership. Should have kept my Honda with 170,000 miles and no problems!!! Seems like this is a consistent problem with Toyota and wonder what kind of run around I will get on Monday about how normal this is???

#296 of 304 Transmission problems intake related? by kbetts1

Dec 01, 2012 (2:39 pm)

I modified my intake (removed the carbon filter). The problem with shifting went away and I had significant more power (no downshifting on hills) and 2mpg increase. It didn't happen right away because the computer had to learn the new air flow. After 2000 mi I'm convinced.
 
I think the Canadians and other none 50 state cars don't have the carbon filter and I was wondering if they had the same problems we've experienced
