99 ford contour jerks like it is skipping out

Mostly occurs at high speeds and climbing hills. Could it be a transmission problem? Or a fuel pump?

are you up to date on your maintenence? you are due for spark plugs, or you may have a coil going bad…

I don’t know if you have a tachometer on that car, but if you do, if the needle does not go up suddenly when it jerks, then it is most likely not the transmission.
