Windell, I would be concerned about the vehicle speed sensor in your Cadillac. If your transmission doesn't know how fast you're going, it doesn't know when to shift. And also - the speedometer will go to zero. Check the sensor and wiring at the sensor. Have a professional diagnosis performed. Good luck, -Dave
