Driving approx 35 mph, there was a loud pop and noise then the car started grinding and transmission locked up. No gears, car locked up and came to a halt. Could not go backward or forward when put into gear, just had a loud grinding sound. Sound was so loud I thought the transmission had fallen out. Before this happened I noticed that when the car had been turned off for a while then started and put into reverse there was a loud clunking sound, almost as if you had tried to put the car into gear without putting your foot on the brake first and it would leap into gear.
