Last weekend my sister borrowed my car and did a little damage. Her friend got stuck and she tried to help, but got the explorer stuck. She dosen't know anything about cars and just keep spinning the tires until they wouldn't spin any more. Now my car is a little messed up and she is going to pay to get it fixed. The transmission is doing some weird things, when pressed it sort of whines for a second then goes. My friend thinks it's the torque converter, is that a possibility or what else should I have checked out. Thanks for the help.
