I have a mazda protege 5 famila 2003 and ever since yesterday it has been shifting gears hard and slipping. And if i go to 4th gear it wont move it just revs up all the way. But in 1st 2nd and 3rd it works okay. I checked the transmission fluids and all that and its fine. I even put more in. And it barley started doing this.

Other info you might need

*automatic
* has about 70,000 miles on it


thank you
