97 Stratus doing funny things

My girlfriends father put a new transmission in her 97 Stratus. Now when i go to start it, turning the key to the ON position makes the starter run for about 5 seconds. After it stops cranking it wont turn over again until you shut the power off and turn it back to ON. Moving the switch to start does nothing. Also, on the dash, it says the car is in drive even though its in park and will start. Any Ideas?
