Anaasociate of mine has an MKS 2010, 6 speed auto tranny, says he has some Lagging / Hesitation issues too. Too many gears. I have a 2010 G37X, 7 speed auto tranny, That's worse...Too Many gears for the TC to handle with speed for the right gear and downshifting is delayed (hence the Lagging), because you enter the top gear too soon. With the Infiniti, at 35 mph, she will be at 1400-1500 rpms, probably 7th gear, (if I shift to Manual mode - it reveals which gear I'm in), and I feel the lumbering of the gear box. These theings are affected by many, many, variables at the time you are driving according to the Infiniti Service Manager: outside Temps, barometric pressures (!!), road incline, etc., etc.,,, Yes totally computer controlled throttles, Transmission with Control Modules (that's why they are referred to as TCMs), and of copurse, ECUs (Electronic Control Units [the mainframe & brains of the car]. The lagging/hesitation in my G37X (which my old 07 G35X did NOT have - 5 speed tranny), atimes in stop n go traffic on some days is horrendous, other days it will vary. Man, I miss my 07 G35X - should have bought that car at lease end....Too late now. Newer is Not Always Better... BTW, this was donme to increase the mileage of the Fleet by many Manufacturers - 7ATs, 8ATs, and the 6ATs, by using top gears quickly helps to increase the mileage ratings of the cars.

"...by using top geras quickly..."
Not so much as having enough gear ratios available to most closely, more closely, simulate an actual CVT. Be in the right, most optimal gear ratio for current, all around road conditions. Makes for a whole lot of "shiftiness".
#20 of 36 WHY DOES V8 FORD EAT UP GAS

I HAD MANY V8 CARS AND THIS IS SO BAD ON GAS WHY??

If it is a V8 it is not a 2011 Taurus or any Taurus for that matter. Is it an older Crown Vic, maybe an old police car? If so that may explain the poor mileage.
The 2010 Crown Vic is rated 16 city, 24 highway mpg.

Jimmy, I realize your post is over a month old so maybe you have gotten this resolved. However, if I am reading the description of your problem correctly, it is NOT normal.
Ford issued a Service Bulletin for 2010 and 2011 Ford products with the transmission like yours - TSB 10-21-2. It involves replacing the TRS - transmission range sensor. I had the problem with my MKS. It was very intermittent. Basically, it would attempt to be in the wrong gear at the wrong time. It would even slip into neutral while crusing. Occasionally, it would attempt to take off in a higher gear and then drop back to low, causing the sensation that you describe. Replacement of the TRS per the TSB solved the problem.
If you are still having a concern, have your dealer check this out.

Interestingly, we have not experienced this problem again since I posted in June 2011. Orginally it occurred every other week for a while from a standing start and with time the incidents have completely stopped. I told my wife that I think we were really a little too light footed on the accelerator from a standing start when we first took deliverly of the car in Nov. 2010. We just had the car serviced 8500 mi. at the dealership with no problems other than I got a 4-wheel alignment under warranty just to check and sure enough the toe was out on one side. My experience with new cars is that after the suspension has time to settle/adjust to road use miles, you had better check the alignment.
Bruce, thanks so much for the service tip and I will keep that in mind in case the problem occurs again. So far, we love this 2011 Taurus.

Glad to hear all is well. I may have over-reacted to your post since it sounded somewhat familiar. Still, I suggest you keep an eye on it. Here is the verbiage from Ford's bulletin:
Some 2009-2011 Edge, MKX, Taurus, Flex, MKS
and 2010-2011 MKT vehicles built
3/13/2009-6/30/2010 and equipped with a 6F50 or
6F55 transmissions may intermittently exhibit
slipping/neutral out, 5th gear start from stop,
electronic PRNDL error, backup camera on in Drive
or speed control dropping out intermittently, this
may be due to high resistance in the transmission
range (TR) sensor.
The complete TSB can be found by googling "6f50 TSB." Your original description of the stumble reminded me of what mine did - starting out in 5th and then immediately going back to low. It was very intermittent - maybe 3 times in 2 months. If it hadn't been for the bulletin, my dealer would never have found the problem.
#25 of 36 2011 Taurus Limited A/C operations
Sep 27, 2011 (10:32 am)
I have a 2011 Taurus Limited. My A/C seems to cycle on and off every 10 to 20 seconds
as I'm driving even though the cabin temp has not reached my the set temp. I can feel the
difference in the air as it comes out of the vents. I took it to the dealer. They said the coolant
pressure was ok...the cycling times was ok. I was told that the compressor is suppose to cycle
often to save on gas milage. I would think this would eventually cause the compressor to fail early.

The A/C system has a pressure sensor that will disable the compressor when the high side pressure reaches ~375PSI. Restarts it at ~250PSI as the liquid refrigerant is used via cooling the evaporator.
"I can feel the difference...."
Unless the system lacks a (big enough??) dryer/reservior that shouldn't be.
The other reason for the compressor cycling might be the engine coolant "approaching" too high a temperature.
#27 of 36 Taurus 2011 SHO bucket Seats
Sep 29, 2011 (4:36 am)
I've had my Taurus for about a year with 10k miles on it. Great car, but I think my driver bucket seat is starting to list to the right and back. Nothing out of the ordinary from a driving perspective. Mix of highway/city driving with drivers between 150-200 lbs.
Anyone having similar issues, seeing reported problems on this? I'd appreciate context or links as well if applicable.
