Q: Is my transmission going in my car?

asked by on April 24, 2016

Everytime i start my car it revs itself up to 4rpm and holds for a moment then drops down to 1- 1 1\2. As soon as i put my car in drive it will either "chug" and not allow me to accelerate or as soon as i press on the gas my car will go and basically drive itself(same in reverse only with othe the chugging). When i do drive my car bounces between 1 1/2 and 2 rpms. There are also points were my breaks are great or almost dont work. I have just replaced the o2 and speed sensors and the thermostat almong with unplugging the battery.

My car has 170000 miles.
My car has an automatic transmission.
