Bumping this up? Updated.
Russ if you are reading, earlier you said to find out and I took her in and got a suggested service (it was time mileage wise) and they stopped but they are back now and more often.
I took it back in and they promptly told me I needed a new trans! The statement was, "My trans guy says he has seen this code before and it will not be long before it stops pulling". He quoted me $3500.00 for a re-man trans. I got my car the hell out of there. No way they had time to check the harness and such much less no description of the worn part(s) or issue.
I have her at another shop for another opinion, they will actually run tests. The tech is supposed to be very reputable and experienced. He looks it over tomorrow.
I have no idea what is acceptable slip or not. I made the attached log today, it starts off me sitting at a light and I eventually get her up to speeds and hold her there at different MPH's.
I have to play it back @0.2x to follow. You guys should be able to tell pretty early in the log.
Is the slip excessive? Thanks
