Whenever I drive my car, I get the amber warning lights of " HDC not available system fault, gearbox fault, and traction control not available drive with care. " but the car shifts normal and drives normal.

Yep, this happens when one of the ABS wheel speed sensors goes out. You will need to run the ABS codes to see which one it is. Please follow this guide and I have included how to change out the ABS sensors in case you need them:

Have you seen all these symptoms before? I didn't realize the ABS sensors would throw a gearbox fault.

It could yes, but we should run the codes to see what comes up.
