For some reason my tap shift was randomly not complete a gear change on first try. Then would fail more n more often, finally it failed all together, I bought a brand new steering wheel, the only way to get new shift buttons. And STILL don't work! Ordered a new clock spring but have not received it yet. All other wheel controls work fine. Any ideas? Maybe a TCM reflash? The TCM on my year is inside trans pan. Maybe a reflash would work? Help!!
