Thanks for the detail on this. I am happy to say that the extra oil in the engine did not cause this.
When you add more oil you will most likely not even notice what it does. If the oil is high enough you will get the crankshaft slapping the oil and this will aerate the oil which can cause oil pressure issues that you most likely will see low oil pressure.
However, it will not cause the vehicle to jump or jerk when coming to or at a stop.
This is caused by a possible transmission issue. This means we need to do a couple things. First we need to start with checking the fluid level and condition of the transmission.
I attached the process below on how to do this.
Next while I doubt there are any codes we need to check and make sure there are none.
If the fluid is ok and there are no codes then we need a little more detail on when this is happening. Are you coming to a complete stop and then letting off the accelerator and it jerks or is it coming to a stop while you are braking?
Does it feel like someone is bumping you in the rear of the vehicle?
If this jerking or jumping when coming to a stop I suspect this is an issue with the vehicle shifting firmly into 1st gear but we need to get a little more info to figure that out.
Let us know about this info and then these questions if this all checks out and we can figure out what to do next.
