Check Engine Light and Transmission Won't Shift Correctly on Hyundai Tucson

Problem Description and Possible Solution

If the automatic transmission does not shift properly and the Check Engine Light illuminates, the speed sensors in the transmission may have failed. The sensors are simple and inexpensive to replace.

Every once in a while (once a week, maybe). The transmission will shift hard. Then Check Engine Light comes on, and I'll notice that it'll now stay in 3rd gear. If I manually shift, it'll work for 1,2,3 (can't go to 4th). Usually, when I stop the car, and start it again, it'll shift normal again.
I have had my 2 different sensors replaced. one was a thrust sensor ? the other accelerator sensor? now my check engine light will come on when i accelerate and the car jumps, bucks, and it stays stuck in one of the gears and when i step on the gas it does not accelerate. then with in two minutes it shuts off. I have brought the car to hyundai numerous times and they say they can not find anything wrong but the last time they said i needed new spark plugs and spark wires. and it would only cost 642.00 wtf my car does not have that many miles and who the heck has that type of money nowadays. i have an extended warrenty that runs out next mth. please some one help???? i dont feel safe in my car with my 3 kids.
transmission shifting problems
Transmission not shifting Speed Sensor failed. Replaced
My Hyundai dealership told me it was the fuel filter in the tank, so I changed pump and filter, still not fixed so I changed the accelerator sensor and mass air flow sensor. still accelerates when driving RPM's going up and down. If I drive it by using the manual shift it's OK. Any suggestions.
So far only occasionally but it is getting worse. Car does not shift properly, up or down. It gets stuck shifting between gears, it jerks and sometimes clunks hard when it does finally shift. Hyundai says they will only look at it if they can replicate the problem. I had the same trouble with them when trying to get my door locks fixed when the car was new. They still don't work properly and the driver's door will lock itself while the car is turned off, sometimes they all lock. I've never been able to leave my keys in the car for any reason for fear of being locked out. This transmission problem though worries me. I was told to wait until it got serious to bring it in if I didn't want to leave the car with them for an extended period of time. (are you kidding me, they are well aware that there is a problem, fix it)
3 transmissions later and no clue what problem is yet
transmission shifting problems
Shifts slow from 2 to 3rd gear and then downshift fast when come to a slower speed area
HAD THE SAME PROBLEM TOOK IT TO HYUNDAI and they replaced the ATF-SP-IV-M #00232-19057 and the Harness # 46307-38650
the code was PO713 for tranny temp sensor. Fixed it for free.....still under warranty
When I accelerate and the car jumps, jerks , and it stays stuck in one of the gears then finally goes to the next one. Sometimes clunks hard when it does finally shift. This only happens when I suddenly accelerate. This never happened before. It seems a this is happening to a lot of people. I wonder what it could be???
Speed sensor failed.
Engine light came on - feels like transmission is slipping on acceleration, especially a hill. Just happened yesterday (Aug 8, 2016) so haven't taken it in yet. Trying to see if other Tucson are having the same issues.
Rear axle sensor
Same as others
It works only in 4wd and no more than 25 mph
Low fluid light on and shifter doesn't stay in drive or park
Check engine light came on. It needed a transmission sensor that was under the transmission pan along with a new filter. Also supposed to add new transmission fluid, drive around a bit, and then flush the system.
Low rpms. Trouble shifting. Check engine light is on. Cuts out at 64mph on highway. Will not go any faster. Not fixed yet.
the shift gear does not work and the gear is stuck on 2nd
