1st gear transmission jump

my wife thought I was being an ass in my driving when the car did this! I told her it was not me and I was thinking also that the tranny needed a 'reflash' reset as it was originally delivered in Germany! Long story short - it was the fuel pump! We got it 2nd hand but had the sense to buy the used car warranty which did cover this. The engine ran fine and usually did this lurch/jump thing after a rolling stop too. Test the fuel pump and replace the fuel filter as this is always a good idea when changing the fuel pump as well. Its an easy fix and you can find the youtube video online. Last resort would be to reflash the tranny as you suggested but check the fuel pump pressure first. Good luck!
