Changed engine oil and overfilled it, my car now jerks sometimes?

Me and my friend changed my engine oil but somehow overfilled it, my car now jerks sometimes trying to go into first, the RPMs will go to 3,000 before shifting sometimes. It does the same in reverse. When I go into second and third the shifts are smooth and the car drives fine while in higher gears. Could it be a problem with my spark plugs or coil packs?
