I purchased a 2017 Chrysler Pacifica about 1 year ago. Sometimes when I start from a stop, or when I'm accelerating the transmission jerks, or pauses between gears. It almost sounds like the engine cuts out. I have taken it in for repairs, and was told that the transmission fluid needed to be flushed and replaced. I did this and it didn't help at all. I really depend on this vehicle, and am a single grandmother. Please help! I need some direction...

There are software updates that address this.

I know you're the electrical Guru but this link I downloaded as it pertains to stalling and power steering but I heard something to this effect about the '17's and up electrical issues with transmission issues also. The negative ground battery terminals on the bottom of the engine that hook to the frame get corroded and causes lots of other issues to..

How do I get the updates, and how much can I expect to pay?

Find out if other local shops can do it rather than the dealer to save $

Thanks! I will try that.

Thanks! I will try that.

Try your local transmission shops to they might have the program

I did the software update on my transmission, would not advise. I am now experiencing so many issues, all transmission related. There is a major issue going on with this year and model, I wish they would recall it.

Did they reset the transmission to relearn after the update? If not there is a video here I posted on how to do this.

Software updates are critical. If there was not a need for then the engineers would not waste their time developing them. I get every update for my vehicles when they are available.

Solved the jerk with a KUNFINE Car Electronic Throttle Controller, ($80) or you could use another brand (Pedal Commander $350) or another $80 brand. The controller ends the problem when set on ECO 3 or higher, or F1-2. Take a picture of the connector on your gas pedal and send it to the seller so they send you the correct connector. Adaptive memory reset only worked for a few days.
1) Turn the start switch to run, but do not start the car. All trouble lights are on and the fans in the heating and cooling systems are on if that was the position they were left in. Wait for chimes to stop.
2) Push the gas pedal all the way to the floor and hold it there for 10 seconds.
3) Turn the start switch to off with your foot still on the gas pedal.
4) Release the gas pedal, but do not put your foot on the brake pedal
5) Wait for 2 minutes before starting, or exiting your car.
IMO the problem is a bug in Chrysler's programming of the ZF 9HP48 transmission to respond to the gas pedal, but a controller will compensate for it. I never had to take it to the dealer. After three months I begin to occasionally feel hesitation so I plan to reset the transmission again.
