Check your engine mounts. It is possible that they are worn and/or broken.

Looking to do a motor swap in a 98 sunfire...what motors fit?

It is true, you can only put another 98 2.2 liter in it. They did come with a 2.4 liter but you have to swap the motor, transmission, wiring harness, computer, and God knows what else. I would go with the 2.2 liter and check into some performance aftermarket parts for the 2.2, computer chip, performance exhaust and so on, somewhere like Summit Racing.

1999 Sunfire GT has started to shift violently with a noticable jolt going from park to drive or neutral to drive while upshifting also seems more harsh.200000 kilometers on car. Cruise control quit...

I recommend you test the tps. Procedure at the link below. The resistance should change linearly as you open the throttle. If it skips and jumps, it is bad.
Repair Guides Electronic Engine Controls Throttle Position Sensor AutoZone...

The signal is on the dark blue wire. Just put your red probe in the back of the connector on that wire terminal and hold your black probe on engine ground.
