I just had my thermostat replaced. My car jerks a bit in stop and go traffic on 2006 Volkswagen Passat

only when it changes gear from 1st to 2nd and back. Does this car need
transmission fluid refill or change? Is this a serious transmission
problem? I am very scared now. When I took it in the engine light was on
but they said it was the thermostat P2181 code.
Please advise.
