You think so??? I told him the same thing....but he said he had been easy on it all day but was kinda hard on it the night before!!!! when it failed to 3rd he was only running like 30 mph in traffic.

The code is caused from the clutches slipping (c2 or c3) ,turn the power down or build the trans not many other options .
