Most Reported On
P0780 is an OBD-II diagnostic trouble code meaning “Shift Malfunction (Shift Error).” P0780 is a general transmission code indicating the control module detected a shift malfunction — the transmission did not change gears correctly or did not achieve the commanded gear during a shift. It is often a 'parent' code that accompanies more specific solenoid or gear-ratio codes that pinpoint which shift failed. Symptoms can include harsh, slipping, delayed, or missed shifts, and possibly limp mode. It is generally drivable short-term but should be diagnosed promptly to prevent transmission damage. This code is most commonly reported on 2004-2008 Acura TL (Base, Type-S), 2016-2022 Acura ILX (Base, Technology, Premium), and 2000-2003 Lexus RX, plus 2 other vehicles, with repair costs ranging from $150 to $5,000.
