2007 PT Cruiser rough shifting

I have a new 2007 PT Cruiser, (non-turbo) with automatic transmission. It
has about 1,000 miles on it.

From a cold start, the trans shifts "hard" from first to second gear, and
the rest of the shifting is smooth. When decelerating, it will also hard
shift from second back into first. This seems to go away after the engine
and trans have warmed up to operating temperature.

Is this normal? If I disconnect the battery cables to reset, will it
"re-learn" it's shifting pattern?

Thanks for any advice you may offer.

No it will not have any effect on the trans shift points. You only had this
vehicle for a few days, are you just not used to it???? What was the vehicle
you had before this one? There are no TSB's out for any issues on the trans
and if the trans developed a problem the check engine lite would turn on.

I had a Nissan Maxima prior to this vehicle. The hard shift only happens
from a cold start (cold being a relative term here in Hawaii), and it is a
definite hard, lurching shift from 1st to second. Second to third is
smooth. In addition, the same hard shift occurs when decelerating, or
applying the brakes to stop. The problem goes away once the engine is up to
operating temperature. There is no check engine light (of course).

I would let it go another thousand miles after checking the AT fluid level
and see what happens. Wierd shifting in a new Chrysler is normal.

 

drive it another 1k the vehicle is still learning your driving habits and it's
parameters then if it is the same have the pinion angle checked
