P0742 Chevrolet -

Question

I replaced all 4 solenoids in the Transmission and changed the filter there are no metal fillings or any foreign material in the pan or fluid but i still get the code PO742, What would cause this?

Answer 1

Hi there,

Since you have changed the solenoids and have checked the fluid etc, it's highly possible you have internal mechanical issues with the transmission or wiring. Here is some more info for you.
