I have just sold my 2005 Bonne. At 88k it'* transmission died.
My owning GM product is history now. In order I lost transmissions on:
1998 Olds 88
2001 Pontiac Montana
All had less than 95k miles, all went without warning.
So.....time for something new.
But I truly appreciate the great information you all have given me, both specific to my needs and good general info.
