Jerking motion while driving - occasionally

Chrysler Town and Country 2012 Touring 248000 miles
While driving, mainly slow speeds (40 and under), the car jerks like there is a transmission problem but it is not shifting at the time.
One engine code - a possible inefficient catalytic converter, but that has been on there for a while.
Found this site, thought I would ask. Everything else is great, no problems. The alternator died just recently and was replaced, and the front motor mount was found to be cracked and was replaced.
