I have a 2003 Bonneville SSEi. It has 39000 miles on it and the transmission has already been slipping on me, but only every once in a while. it has slipped 5 times going from 1st to 2nd in the last 3 weeks. It is not throwing any codes and there are no metal shaving in the pan or the filter. Any ideas of what is going on? I really appreciate any help anyone can give me!
The dealership diagnosis is they don't know. They can't get it to throw a code and it will not do it while they are driving it. They have driven it 30+ miles and still know nothing. They don't think it is anything mechanical since it is intermittent and are thinking it is an electrical component. Bottom line they won't do anything till they know for sure.
