More than likely, we have an issue with the torque converter, but we need to confirm this is an auto transmission, manual, or CVT first.
Next, we need to check the fluid and find out if the fluid is full and in good condition. If it is not, we need to refill it and see if the operation is any different.
I don't expect this to fix the issue but if it changes the issue then we have internal issues with the torque converter.
What I suspect is happening is the converter is trying to engage but it is just slipping or not fully engaging and that is causing the vehicle to jerk.
We need to also check for codes and see if there are any that will point us in a different direction.
Let's start with this and go from there.
