I replaced TCM and it's been programmed but my cruise control is still not working and the RPM seem to still be high. It's shifting fine it's driving smoothly yet I don't know what else to do. I have a Chevrolet HHR 2010 LT. Any help or suggestions would be appreciated

 

Any other issues like , is the CEL on? Are the brake lights working? The third brake light should have 4 bulbs all working.

 

Why did you replace the TCM? Do you think it has something to do with cruise control?

 

Million dollar question - Why did you replace the TCM?

 

Probability of learning that is roughly equal to the interest rate being paid by the major banks.
