09 uplander 3.9 l trans issue
It has 88,412 km or 54936 miles.
When I put it in drive it takes too much time to engage. If I put it into low it engages normally. I first noticed the problem when I hit the throttle hard from a stop . It revved up and then banged hard into gear. It seemed to be slipping at times. Shifting it manually it seems to work fine. There are no codes. I put my cheap scanner on it and in the trans section for live data it shows 0 rpm for the Output Shaft Speed Sensor as I'm driving it.
Has anyone else encountered this? I've tried online for info on this with no luck. I don't know where that sensor is and can't seem to find any info without having to spend money.
Any help is greatly appreciated.
