Customer Question
Check engine light came...

Check engine light came on, code p0742 came up.

Mechanic's Assistant: Does the light stay on, or does it blink?

Stay on, also car is shifting odd

Mechanic's Assistant: What is the model/year of your Chevy?

Impala,2005

Mechanic's Assistant: Are you fixing your Impala yourself? What have you tried so far?

Only thing I have done is oil change and tires, it only has 135000 miles on it. All I have done is reset the cpu

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I reset the cpu by disconnecting the positive side of the battery

This usually means the Torque Converter Clutch (TCC) Solenoid has failed or valve inside valve body is sticking. Are you trying to fix yourself or want to know what to expect at a shop?
