1st time posting. I own a '97 tl. Driving home with wife when my car started making rattling noise which sounded like it was coming from the transmission or near front middle of engine. Then the car stopped suddenly. Will not go forwards nor backward after shifting gears. The engine runs fine. Front wheels are locked. Wrecker had to drag car on bed. Front wheels were crying. Any ideas what the problem may be?? Thanks!!
