P0780: Shift Malfunction (Shift Error)
7 vehicles · 3 makes · $150-$5,000 repair
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 2002-2011 Honda CR-V (LX, EX, EX-L, SE), plus 4 other vehicles, with repair costs ranging from $150 to $5,000.

What you can do yourself, and what needs a shop
Reading the code, clearing it, and watching whether it returns is a driveway job with the right scanner. These steps are not:
- Module programming or software updates — needs the manufacturer software or a J2534 pass-through with a paid subscription.
- Replacing a control module — most are VIN-programmed and immobilizer-registered, so a new one does nothing until it is coded to your car.
- Airbag/SRS component work — a stored fault can deploy a live device.
If the vehicle is still under warranty, check for an open recall or technical service bulletin before buying anything — the repair may already be covered.
