2005 Yukon getting P0784 code (check engine light on)

Asked by Nov 16, 2014 at 09:01 PM about the 2005 GMC Yukon SLT 4WD

Question type: Maintenance & Repair

it was low on transmission fluid and a quart was added. Check engine light still on b ut only drove 2 1/2 miles after adding tranny fluid. Could this cause error or should I spend extra $ to have it looked at.

If it seems to be shifting okay, I would wait to see if the light goes out. If the code is clear it will go out by itself after a default number of start cycles with no codes.
