    6l90 question

    what would cause a 6l90 to shift itself in manual mode at 5300 rpms, but not in sport mode or drive? first time this has ever happened to me actually.

    i believe it was being triggered by the "hot" tabs for some odd reason. can't see where in trans diag, or engine diag this parameter is listed

    got it figured out. nothing to do with the trans, but engine tm kicking in on a single tab option.
