First let me say hello to everyone out there!! Hello!!

Now for the question.

I have a 2000 Bonneville SSEI. The problem is when you put it in drive, there'* nothing...like you have it in neutral. It happened all of a sudden, no slippage or no signs of a burnt up tranny. Is there a sensor or a wiring harness that may have went bad or come loose to cause this? Every gear work except Drive and 3.

Thanks in advance for your help.

Sounds like the linkages need some adjustment. Check the linkages. You will need someone to shift while you watch it move.
