THERE ARE ONLY THREE REASONS:
It was not in park properly.
The car was still moving when put in park
If the first is true it has a serious problem inside the transmission and must be repaired by a qualified person.
If the third is true you need to make sure the car is completely stopped every time! This abuse could easily cause the damage leading to the first example.

I have a 1990 Chevy Lumina and when you hear clunking sounds when going over bumps or dips or if you have ever replaced your strut assembly you should replace the mounts. You can buy a quickstrut online for a lumina. Front is around $180 and rear is around $80. Hope that helps!
you need to put gas in it
At the same interval you check your tires and bring the pressure up to recommended: every month with a new car, and more often if you have a reason to suspect a problem.
Remember to check the coolant when the engine is cold, to get an accurate reading and eliminate the chance of getting burned. Tires too, as they will read high when they are warm.
The firing order for this engine is 1-2-3-4-5-6. The cylinders are 1-3-5 from left to right on the back head, and 2-4-6 from left to right on the front head. The coil pack is 1-4-6-3-2-5 from left to right when viewing from the front of the car.
It's a VATS system. If you know the value of the resistor you can cut the wires going to the lock cylinder and solder in a resistor of the correct value.
Please let me know as well were the abs module is if you ever find it, sssmdg@yahoo.com I also need to know were the flasher module is as well. I have no blinkers or flashers and all the fuses are good
Most oxygen sensors are either on the exaust headpipe just after the manifold or on the manifold. I don't know where it is exactly on the Lumina but that is where you should start looking.
check the transmission linkedge and grease it with your finger with the red grease
look up near the raditor or batt. area i know ford loves to play hid the horn on a lot of the cars.
location is on passenger side radiator , best view of sensor is done by removing headlamp assembly on passenger side. it is approximately 4-6 inches below radiator filler neck
Bad battery, starter, or loose or corroded cables.
If this is similar to the 92 the the low side valve is under the air filter box. Remove the two bolts holding that. It is r134 freon. Add enough so the dryer under the filter box begins sweating. If it leaks out again in less than 3 months you might ought to find the leaking component - tho a can of r134 every three months is tolerable. There is a leak stopper available for small leaks.
The oil sits at the bottom of your engine in your oil pan. The oil takes a minute to build that pressure up and get the oil all through out the valves.
I had a similar problem with a ford explorer once, I checked under the hood and found some air intake pipes/tubes loose and off, this may not be your problem but check that all air intake pipes and tubes are fitted firmly to where they should be.
Look in the engine compartment for the "serpentine belt" path & tensioner diagram. Release the belt tension at the tensioner, remove & reverse operation.
Gm Dex Cool or equivalent. The red color antifreeze.
that is your brakes catching then being pulled just a little bit to the side and losing traction and going back and catching again.
so its catching and slipping and catching and slipping really fast
