Mitsubishi Repair: AUTOMATIC TRANSMISSION, shift linkage, motor noise

Question
I HAVE ALMOST 180,000 HARD MILES ON MY 2000 MITS MIRAGE 1.8L, ONE DAY I WAS DRIVING HOME NORMAL AND I WENT TO PASS, MY TRANSMISSION FELT LIKE IT WENT INTO NEUTRAL, I LOST ALL GEARS. NOW I HAVE A WHINNING NOISE FROM THE BELL HOUSING AREA AND WHEN I SHIFT INTO GEARS I HEAR A ELECTRIC MOTOR NOISE FROM THE TRANS AREA - WHEN I UNPLUG THE HARNESS THAT IS CONNECTED TO THE SHIFT LINKAGE THE ELECTRIC MOTOR MOISE STOPS. PLEASE HELP ME FIGURE OUT WHAT IS WRONG WITH MY TRANNY.

Answer
Forrest,
It sounds as if the solenoids in your transmission may be shot, or even the transaxle control unit is malfunctioning.  Unfortunately, there's not much more I can help with without running diagnostic tests on the transmission itself.  I would recommend having a transmission shop inspect your transmission.  My guess is that they would recommend a transmission rebuild or replacement.  
Good luck!
