My awd warning light will come.on..i know then there is trouble with the awd system....but when this happens i dont have any gears...i put it in drive and it just revs up...same reverse

Hello, it concerns me to hear that your "park gear" isn't there - meaning it won't lock into park? I'm not familiar with that happening, as this is a cable driven shift lever. With the AWD light coming on, it does indicate there is a problem occurring, and based on your description, it does sound like it could be an electronic control concern. Diagnostic testing hands on with a proper diagnostic tool capable of checking this kind of trouble code and monitoring component operation is needed to help diagnose the concern. www.repairpal.com/repair-shops
