I own a Chrysler 300 touring. It’s 2006 and its automatic transmission. I was driving on the highway and I reached 60mph then I heard a sound and a rough push and suddenly the car started loosing speed. It didn’t loose power. Luckily I was getting off the highway and turned on the hazard lights, I made it into a neighborhood and let the car reach 0. When it did I pressed on the accelerator and it started moving. Anyone know what’s the problem?

Did the Check Engine light come on?

You say it doesn’t lose power, but it slows down. I think what you mean is the engine runs normally, but the power isn’t getting to the wheels. If that’s the case, I think your transmission is toast.

Check the transmission fluid level, and if the fluid shows signs of wear & deterioration, schedule a proper transmission service.
