Transmission seems to go in low gear when braking

My car has 181186 miles.
My car has an automatic transmission.

Check you transmission fluid level with the vehicle in park while warmed up. Add ATF F fluid if necessary.

Your vehicle is also known for Idle Air Control (IAC) valve or vacuum leak issues. The IAC valve is located on top of the engine and will cause the RPMs to drop or raise. It is easy to change if you are having the symptoms.

A vacuum leak can be determined by spraying your engine (top side) with a flammable liquid like brake cleaner and listening for a change in the RPM. If you hear a hissing noise while hitting the brakes, you have a bad brake booster. A proper diagnosis of your transmission with special tools can help you narrow the problem down.

There could have been something that went wrong with your transmission. Try driving in 1st, 2nd, 3rd, and reverse to see if the vehicle will move. If the vehicle only moves in 4th gear, then the counter shaft has burned...
