|Jeepster09||My opinion is that to get the good gas mileage the computer is always looking for optium gear, therefore it shifts a lot. I don't think you will get rid of this, it is normal. If it only had 2 or 3 speeds it wouldn't shift as much OR GET AS GOOD OF GAS MILEAGE.|

2015 Impala LT2 54,000 miles
I had a 2012 impala before with the same setup and never experienced a problem with it. I went to the dealer yesterday and bought a 2015 with 54,000 miles on it. I was on my way home and noticed a shuddering when going up hills and a slight hesitation in changing gears. The car is back at the dealer now and they are apparently replacing the transmission. Is this common, or did I just buy a lemon?

I'm having the same issue with my 2015 ltz.
What can be done?If i go to the Dealer I can see
them not finding a code for the issue and going through
many return visits.Cant they just admit theres a problem
and take care of it?

|juleshaw2077||Tranny shifts like this becuase it is an old man car lmfao, 7th gen impalas shifted nicer. IF you dont like bogging down around town, or before the on ramp. PULL your shifter all the way down and use manual mode, thats why it is there lmfao. Its a lot easier on the engine/tranny when your shifting (unless your racing lol), than it is to have the torque converter bog down, and not know when to shift. Just my 2cents. MANUAL MODE is also much safer in the city, dont gotta WOT every time you pull out somewheres.|

Same here. Huge improvement in shifting, but still get the "confused" shudder. Too many options I guess, I can't imagine driving one of the other optional 8 and 9 speed automatics out there...

|baabootoo||My 2015 2LTZ has 34K on it, and nothing has changed. Its been to the dealer many times, and the feeling is that it does that to get the good mileage ratings. It upshifts waaaaaay too early, and the converter locks up way too early also; kind of like shifting a manual trans car early, and lugging the engine. The Trifecta tune did make a world of difference.|

Back in the days of 2 speed power glide transmissions it didn't have so many gears to pick from. Our 2014 2LTZ sometimes has trouble picking which gear it likes best while driving about 25 - 35 mph. Driving faster or slower fixes that or else use the manual shifter. Our Impala has always had that slight shuddering while accelerating moderately onto the highway when leaving home. I think it is normal. We have 41,000 miles on it now. We just returned from a 875 mile trip to D.C. and then back home. It got 33.2 mpg going east and 30.2 mpg going back west. The wind was out of the west.
We have had no trouble with the car and are very pleased with it.

|commodus192||I have a 2014 model with the 4 cyl - the bigger of the two. I have the same issue with the weird shifting. Noticed it the day I test drove it. The car is such a 10 in the looks department and other odd and ends but that transmission really drives me nuts sometimes. Especially at lower speeds in traffic - constantly up and downshifting, making the car hesitate and shudder a bit. My 04 Impala with 220,000 miles shifts smoother.|
