you need to have your car checked to see if it is the if the speed senor on top of the transmission is bad . my cousin had the same problem and i scaned her car and that was the problem.
Incorrect gear ratio, the transmission is slipping.
its probobaly broken get it a service
I think it;s called the shift solenoid in the transmission!
I am having the same problem and have not taking the car to the shop yet
You need to have the transmission computer checked for trouble codes. When the computer detects a malfunction it sets a code and defaults to second gear.
Trouble code P0733 means: A/T Additional Gear Ratio Error In Third Gear
On top of the steering wheel gear cover
check the brake pedal switch
The transmission computer has deteced a malfunction and set a code. Have the system checked for codes.
Your 2000 stratus has a governer in it's engine computer that limits rpm in high gear, thus limiting top end speed if that's what you mean.
It requires a special tool to pull it off.
Replace the fuse, located in the fuse box under the hood..
