Depending on what code you have on the check engine light. Usually replacing one of these units fixes the "limp home mode". Replace these parts in order.
1. Transmission service.
2. Input and output speed sensors.
3. Transmission control module.
4. Transmission solenoid pack.
But do not replace any parts prior to check the check engine light.
