    Cts-v 6L80 trans slip tune help

    I have my 2012 CTS-V running strong but noticing the trans is slipping at the top of a gear. What adjustments are needed to prevent this? The trans seems fine and I wouldn't have noticed this without logging Trans Slip.
    Thank you

    Going to assume commanded and current gear are not the same while that slip is reported...

    This is just a brief error in how its calculated. When it commands a shift the gear is set to the next one before the shift even starts to happen... IF you were at that RPM and truly in that gear thats what the slip would be. It would be very very noticeable if the slip was that bad.

    That makes sense and is great news! I have other issues with the trans tune but this was my biggest concern. Thanks!
