Name is***** goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back,

This could be one of many issue with the trasmission management system .

The only way to find what is malfunctioning is to be hooked up to a diagnostic scan tool ,
this tool will do a scan of the system and see what has malfunctioned and give you a code, from the code you will then know what has to be checked and then repaired or replaced .

This could be anything from any of many sensors .

Don't think you have a mechanical problem but most likely a sensor malfunction ,

A wheel speed sensor,vehicle speed sensor, the mode switch malfunction could cause thisbut a scan is needed so no sensor or parts are replaced that don't need replacing .

If you need further assistance with this issue then please let me, get back to me with the reply button and not the poor or bad service, this way i can get back to you or suggest another expert if needed.

Kind regards Greg
