6l80e shifts killing me

Is it when you're shifting at full noise? If yes, you're hitting the fuel cut

It's not up to the rev limiter. So it must be trans related.

probably just a timing retard event for the shift.

Thanks. Is there any tables to make it more noticeable? It happens sometimes when upshifting.

Hi Hjtrbo,

Do you know why it would do this even if it?s 700rpm even before the actual hard limiter?
Because i have this issue since changing out a converter.
Thanks.
