I have done what ronald said. I also installed a shift kit, due to a line pressure problem caused by a failing pressure solenoid. If you are having a hard jerk from takeoff, you are having a traction control sensor issue. Trust me I own a 2004 Impala ls. i have been pulling my hair out since i bought it.
Good Luck.

All of the shifting solenoids are in side the tranny, by the sounds of if you might be able to try a service on the tranny, new filter and fluid might help alot. try that first before spending alot of money.

2005 chevy impala wont shift from park

I would begin by checking the brake lights to see if they are working. Find a piece of wood to wedge between the seat and brake pedal or have a assistant get in the vehicle and depress the brake pedal while you observe the lights to see if they are functioning. If the brake lights work then the issue is with the shift interlock solenoid or the wiring to the solenoid. If the brake lights do not illuminate then I would go to the owners manual to check for the fuse location and test the fuse.

My drivers heated seat is not working in my 2003 chevy impala and it also shifts hard.

1.)heated seat is usually the heating elements under the seat cover.
2.)shifting is likely a pc solenoid and valve body.CODE associated with this is a p1811.If your vehicle has high miles or there is alot of debris in the pan of the trans,then I would suggest a reman trans.

two things: Pressure control solenoid first. Second issue is the valve body. These are common issues, but 9 times out of 10 its just the pressure control solenoid. Power steering, could have a leak, that causes air,which in turn causes noise or yes, a noisy pump.

Have a chevy impala 2000 with 3800 in it. the tranny has been shifting hard off the stop. If you gradually depress gas pedal then there is no problem with shifting in any gears, but when yor at a stop, and...

You seem to be on the right track. You should replace the PWM solinoid also, that is the most likly cause for the conern. Make sure the valves move good also, high milage may end up needing a valve body due to sticking valves.
Make sure to check your mounts also, that could be the banging you feel.
Also there should be a code in the pcm if it is banging as hard as you say, p1811 is the most common, but that usally has a shudder also.

2004 Impala - 115,000 miles - has intermittent hard shifts

The dealer should know this! The EPC solenoid (controls pressure) hangs up with wear and causes the harsh shifts.

2000 impala ls trans problem

The problem is a known issue with the 1 to 2 shift at hard throttle. The fix is a repair of the entire 2nd clutch assy. in the transmission. There is a TSB about it released by Chevy. It will need that rebuild for the sudder to go away, or you can try and let off it at shift to stretch more miles out of it.
