2022 JEEP GC HEMI 2ROW TRANSMISSION PROBLEMS

Took delivery 4/4/22. Now has 6700 miles. Transmission 100% of the time vibrates when under slight load instead of down shifting. Will always come out of this if sport mode is selected. However running around in sport mode city driving gives me 11.2 miles per gallon. Dealer tells me they all do this and there is no update available. Anybody have similar problem and was there a fix?

I think you're dead on. Can I defeat MDS permanently with out a tuner ecu that voids the warranty?
sport mode or Pedal Commander
  1. FUEL SAVINGS: With Eco mode's significantly slow response, Pedal Commander can increase your Jeep Grand Cherokee L MPG > save you up to 20% in fuel economy. You can use the Pedal Commander throttle response controller as a fuel-saver device.
  2. QUICK & EASY INSTALLATION: Pedal Commander is a simple plug-and-play device that takes only about 5 minutes to install. Pedal Commander is also Bluetooth-compatible, so you can control the unit using our free Pedal Commander app.
  3. WON'T VOID WARRANTY: Pedal Commander will not void the warranty on your Jeep Grand Cherokee L or leave any traces behind on your ECU.

They sold the pedal commander for the Ram diesel trucks. It was figured out by Chrysler and warranties were voided!
