2002 envoy stalled going down road started right back up but had no speedometer wouldnt shift and abs and brake light came on

First thing you need to do Jen is have the systems control module tested for fault codes.

Blown fuse or relay

clutch

Check the small wire on the positive side of the battery cable.

More than likely. one of the front wheel speed sensors has gone bad. I believe the computer uses this input as well as the speed sensor on the transmission to determine shift points. In order to find out which sensor is bad, a technician will need to hook up a high-end scan tool.

Dead Battery

the speedo and odometer are both worked from the VSS ( (vehicle speed sensor)
check for the reason of metal on the sensor end
could have an internal problem that is not allowing the shifting down so have the transmission check out bat an accredited transmission shop

I had the same problem with ABS light and speedometer, I was told that it is the transmission control module. It has not yet stopped shifting but I have had times where it just wont stay running. It will start and then stall. Hope this helps.

See if you can find out if there is a code for the check engine lite and the abs, those can be related if the speed sensor located on the top of the rear axle is intermittantly failing. That sensor sends the speed signal to the pcm and the abs controler witch will also turn off the cruise control.

Could be your Speed sensor that would make the abs light come on because its not sensing the speed you are traveling. I have no Idea why when your gas gauge is on empty it won't shift. May be its the speed sensor and it was just happened to do it right when you where on empty. Does the speedometer work right or is it erratic? Let me Know this sound like and interesting problem I would like to work on and trouble shoot. Your ECM may be going too. There is so much going on Its hard to tell. But I would make sure the speed sensor is working properly first, Ok Talk at you soon. Thanks Bear001... Oh Yeah make sure all fluids are up and in good condition
