    LBZ Hard shifting!

    My tuner has looked through my tunes a few times and everything seems to look okay he said. Is there Anything in the trans that could cause hard shifting but not throw a code? Internal filter and fluid was changed about a month ago spin on was changed about 3 months ago!
