Question

I have a 2004 Pontiac Grand Prix GT that is throwing a P0730 code. What could be the problem with transmission?

Answer 1

Hi there

This code is for incorrect gear ratio. This code can be the result of dirty or low transmission fluid, a problem with the shift solenoids or some type of mechanical issue inside the transmission.
