Question about 1999 GMC Sierra
This could be a lot of problems. There are a couple things ya have to check, the first being the condition of the transmission fluid, if it is dark brown then it means it is burned. You can do a transmission flush but it may do more harm than good. Second would be to see if the check engine light is on, and works. Turn the key to the on position making sure it comes on and then start the vehicle. If it stays on then you need to see what the code is because the sensors to the computer could be faulty and thus causing the problem. Those are two good starting points.
