Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

I used to work for a GM dealer for 17 years.

This can be caused by a shift solenoid at fault or an issue with the transmission valve body in some cases.Cost can run anywhere from around $300 to over $1500 to repair all depending on which component is at fault.Pressure control solenoid is a possibility as well.

The only way to be sure of course as you know,is to have a tech plug in the Tech 2 scan tool to read out the codes then the codes diagnosed from there to locate the fault.

These are some of the common issues for this fault here though and hope this helps.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
