SOURCE: Gear shifter will not go into park
There is a plastic actuator stick under the shift knob. Remove the "horse shoe" clip from the shift knob and remove knob by pulling strait up. You can twist it right and left a very small amount to loosen the knob, but not much.
Once you have the shift knob removed you will see the plastic actuator stick. Push down on the stick and put shift lever in park. If that works, the shift knob or stick is worn out.
Let me know.

sounds like your CV joints are worn out. If the clicking noise gets worse when turning then its a definite possibility. Also check the CV joint boots for splits as this can quickly wear them out. The dust mixes with the grease to form a grinding paste.

It is possible the crossed jumper cables may have damaged the ECM (engine control module).
You can try disconnecting the negative battery cable for 5 minutes and reconnecting. Start the car and drive over 45mph for 3 miles, and see if the performance improves.
If the car still does not perform properly, have the car scanned for trouble codes. Take the vehicle to your local Auto Zone or Advance Auto Parts and ask them to scan the car for codes, they will do it for you at no charge. Write the codes down and respond back.
Good luck, let me know.

The transmission may be in Limp mode. The transmission is on the same fuse as the MAF, O2 sensors and at
least one other sensor - if an O2 shorts out, it will blow the fuse and
the trans will go into limp-home mode. Be sure the trans has power and
the fuse is not blown before doing anything else.
What is "limp-home mode" ? This is a fault mode in which the
transmission either loses electrical power or the PCM deactivates all
of the electronics. The transmission will default to max line pressure.
The driver will have Reverse and 3rd, with manual 2nd available by
putting the gearshift in 2 or 1 (doesn't matter). 1st, 4th, and TCC
lockup will not be available. It will not hurt the car to drive it like
this for short periods, but use manual 2nd to get the car moving, and
be aware that the trans will generate more heat than normal while
operating in limp-home mode due to increased torque converter slippage
during 2nd gear starts and no lockup in 3rd gear.
Trans does not upshift out of first, speedometer reads zero at all times: VSS failure. Easy fix on rear of transmission, but xmember must come out to access VSS.
Car goes into gear but feels very sluggish like the brakes are dragging,
but it will roll easily (starts out in 4th gear), you manually shift to
2 to get it moving, once it's moving you put it back in OD and the car
shifts 3rd to 4th on its own and locks the converter at the appropriate
time: ShiftB solenoid failed: Easy fix in the pan. Or a wiring problem
from PCM to trans.. or PCM.
No 1st or 4th available; trans shifts 2nd to 3rd by itself in D or OD and locks the converter : ShiftA solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.
Transmission does not shift automatically, only manually. Swap in a known-good PCM, check wiring, check other sensors such as VSS and TPS.
3rd gear starts, can manually shift through all gears. When car has
been turned off for a bit, then back on it will run normally.: VSS
dropoff w/ Hi-stall converter. The rpms are too high, but VSS is
showing no movement. Happens after a tire burning take-off. Doesn't
store a code, will not throw a CEL (I've heard that it will store a
code if it happens 3 or more times). Cure: Reprogram PCM for VSS
dropoff -- PCMforLess knows about it.
Here are just some of the common things you have described with the issues your transmission has. Good luck and keep me posted.

If you can afford a Mercades you should be able to afford to have it repaired..
