Isuzu 2014 auto gear change rough is this normal?

No
ask your mechanic to check this?
some cars, we dont your car IN USA , sorry, why ask us?
but some AT cars
have P/N switch
power and normal
power is aggressive shifting and N = grandma.
teenage/grandma mode.

and most modern cars
the transmission has a learn mode!
if the car battery dies, then is corrected.
the trans goes to learn ,so drive it and in few miles
it learns how you drive and how to shift correctly
all modern cars do that


my modern jeep has like 15 learn modes.
the newer the car the more learn modes.
(smart cars)
