I had my battery changed and noticing a hard shift when going into second. Could this be that the car is relearning itself.

I had my fuel filter changed and my trans flluid checked still clean and doesnt smell bad.

I had my battery connectors of the battery for almost a hour and reput on.

But when I had my battery changed in the past it didnt see to be a problem at all.

I noticed a slight stall as well that comes and goes but after i take my foot off the gas everything is fine could would you guys recommend a fuel pressure test.

And there is no codes at all.

Thanks for all the replys in advance
