On my way home I was going about 25mph, the car started losing power and started to stall. I pulled over and took about 15 minutes and started it back up and it started fine. I made it to napa and one of the guys took a look at it and said it was the accelerator pedal because obviously it wasn't moving. So I got that and had my father put that part on and put it into drive and it still did nothing. I park it back in the driveway as I normally would with the little power that it did have, and the transmission just made a loud thump. My father tells me to start it up and I started it up again as I normally would and the transmission starts whining. This just happened out of nowhere, there were no signs of anything about to happen. No lights were on, no weird noises, and the power was doing completely fine.
