I got my truck about a month ago and love it!! I have done several full throttle launches (racing people) and the torque converter has never shown it slipping when locked up (on my edge gauge). Today I was towing a trailer back from our cabin, going downhill in T/H mode about 35 MPH. I Hit the brakes to slow down for a corner and my truck downshifted from 3rd to 2nd and showed a slip of 27%, I continued to show it slipping until I kicked it out of T/H mode and gave it some throttle, it unlocked and shifted up a gear. The rest of the way home I stepped on it a few times and it never showed a slip again??? It has only done this one other time, again when it was downshifting in T/H mode. So what the heck, Is my edge gauge just getting a bad reading or was it really slipping?? It never heats up and has never thrown a code.. Do I need to worry about it at all?? Any help on this issue would be great. Thanks!!
