Hello. Something went wrong with my transmission. I made a stop, and when I tried to move forward, I felt a very strong bump in my transmission. The car stopped working after that. The car won't move forward, park, and reverse. It feels like the car is on neutral. However, when i do try to reverse or park, the car makes a weird rattling sound like gears grinding each other. I used my scanner, but it could not detect anything. . . . Also, when I switch to standard gear or mechanic gear, the dashboard does not the change (eg. 1st drive, 2nd drive, 3rd drive , etc). My car is 4 x 4 wheel drive.
