has anyone experienced this before i have 2011 maxima sv 85k, KM on it, i find that when i go from D to Ds only half the time the rpm rises up into the 3000 rpm and then when i brake to a complete stop hard or not hard i feel a jerk and its distracting almost feels like someone hits the gas a little.

Has the cvt oil ever been changed?

This is normal. You are experiencing engine braking, which the CVT simulates downshifting in a manual vehicle using the engine force to slow the car. Then you are also experiencing the torque converter locking around 11 mph causing another jerk.

Here are my findings/experiences so far.

• Shifting from D to Ds:
  • Under 30MPH - No jump to 3K RPM.
  • 30MPH and up - Jump to 3K RPM and then back down as needed.
• Braking while in Ds Mode:
  • Gentle braking to normal stopping - No "downshifting".
    Your "normal stopping" brake pressure and speed of depressing the pedal may vary from what Nissan has determined to be the "normal/average" driver though.
  • Hard braking such as a emergency stop or "some-id10t-driver-just-decided-to-swerve-into-my-lane-and-didn't-bother-to-signal-or-check-their-mirrors-for-any-objects" braking - CVT will simulate the "downshift" for more engine braking and preparation in case you want to use all 290(+) horses to quickly merge over to another lane and keep up with traffic and avoid a collision with anything.
• Torque Converter:
  • Locks up at around 16MPH.
• Going downhill:
  • D Mode:
    • The engine will downshift smoothly to utilize engine braking and prevent you from speeding up going downhill.
      You will feel a slight pull back sensation, but nothing major.
  • Ds Mode:
    • The engine will downshift more abruptly to utilize engine braking while downhill; for that sports car feel.
      You will definitely feel that downshift.

How many jerking sensations (you dirty mind you...) do you feel?
Any more than 2 while stopping might warrant a trip to the dealer for a checkup or at least posting more questions for us to try and help.

The TC unlocks when you come to a stop...
