P0780 on Acura
Shift Malfunction (Shift Error)
P0780 on Acura vehicles indicates shift malfunction (shift error). Au7o has documented this code across 3 Acura models — most commonly on ILX, Integra, TL. 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. Typical repair costs on Acura range from $150 to $4,500, depending on the specific model and root cause.
Common Causes of P0780
- •Low, dirty, or degraded transmission fluid
- •Faulty shift solenoid(s)
- •Worn internal clutches/bands or valve body wear
- •Wiring or connector faults in the transmission circuit
- •Stuck valve body passages from debris
- •Faulty transmission control module
- •Internal mechanical transmission wear
P0780 on Acura by Model
Acura ILX(1 issue)
- 8-Speed DCT Shudder and Low-Speed Jerking2016-2022
The 2013-2015 ILX 2.4L with the 8-speed dual-clutch transmission (DCT) exhibits severe shudder, jerking, and hesitation during low-speed driving. The clutch packs engage roughly in stop-and-go traffic, and the transmission frequently hunts between gears on slight inclines, making city driving extremely unpleasant.
Acura Integra(1 issue)
- 4-speed automatic: shift solenoid failure causes D4 light flash, missed shifts, and limp mode1994-1999
The Honda BAXA/MAXA 4-speed automatic in the Integra is notoriously sensitive to fluid condition and shift-solenoid contamination. Solenoid A/B failure causes flashing D4 light, harsh or missed 2-3/3-4 shifts, loss of power in D4/D3, and sometimes speedometer drop-out. Integra often faces delayed or missed shifts and manual downshifting difficulties in automatic transmissions. Shifting problems in the 1998 Integra's automatic transmission can stem from a clogged transmission filter or screen restricting fluid flow. This causes poor hydraulic pressure, leading to missed 4th gear shifts and failure to downshift. While driving, the D4 suddenly lost almost all power, wouldn't shift, and the speedometer stopped working. Codes returned were Automatic Transaxle FI A circuit failure and ELD error.
Acura TL(1 issue)
- Automatic Transmission 3rd Gear Failure2004-2008
The third-generation TL automatic transmission is notorious for 3rd gear clutch pack failure, often between 80,000-120,000 miles. The 3rd gear clutch pack burns out due to insufficient fluid flow and a weak pressure regulator design, causing the transmission to slip, flare, or refuse to engage 3rd gear entirely.

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. On Acura specifically, this code is documented across 3 models.
