P0776 on Hyundai
Pressure Control Solenoid B Performance/Stuck Off
P0776 on Hyundai vehicles indicates pressure control solenoid b performance/stuck off. Au7o has documented this code across 1 Hyundai model — most commonly on Sonata. This code means the transmission's Pressure Control Solenoid B is not performing correctly and is behaving as if stuck in the 'off' position. Pressure control solenoids regulate the hydraulic fluid pressure used to apply clutches and bands and to control shift quality, so when one underperforms the transmission may shift harshly, slip, flare between gears, or feel inconsistent. The transmission control module sets this code when the fluid pressure or response it measures doesn't match what it commanded from that solenoid. It generally indicates a hydraulic performance issue with the solenoid or its fluid circuit rather than just a wiring fault. Typical repair costs on Hyundai range from $600 to $4,500, depending on the specific model and root cause.
Common Causes of P0776
- •Stuck or failed pressure control solenoid B
- •Low, dirty, or degraded transmission fluid
- •Clogged solenoid screen or valve body passages
- •Sticking or worn valve body components
- •Wiring or connector problem at the solenoid
- •Internal transmission wear or pressure loss
- •Faulty transmission control module

- A6MF Six-Speed Automatic Valve Body Bore Wear Causing Shift Flare and Harsh Shifts2011-2019
The A6-series six-speed automatic fitted to the YF and LF Sonata wears the aluminium bores that house the solenoid pressure-reducing valves. The worn bores leak line pressure internally, so clutch apply pressure falls and the transmission either flares (RPM jumping between gears as a clutch slips) or bangs into gear once the pressure command finally builds. Reports of the wear appearing by 40,000-60,000 miles are common. Symptoms are frequently misdiagnosed as a bad solenoid pack and the solenoids replaced without addressing the bores, which returns the fault within months. This is distinct from the wet dual-clutch (DCT) shudder complaint on the turbo and hybrid variants - the A6MF is a conventional torque-converter automatic.

What does P0776 mean on Hyundai?▼
P0776 stands for "Pressure Control Solenoid B Performance/Stuck Off." This code means the transmission's Pressure Control Solenoid B is not performing correctly and is behaving as if stuck in the 'off' position. Pressure control solenoids regulate the hydraulic fluid pressure used to apply clutches and bands and to control shift quality, so when one underperforms the transmission may shift harshly, slip, flare between gears, or feel inconsistent. The transmission control module sets this code when the fluid pressure or response it measures doesn't match what it commanded from that solenoid. It generally indicates a hydraulic performance issue with the solenoid or its fluid circuit rather than just a wiring fault. On Hyundai specifically, this code is documented across 1 model.
What causes P0776 on Hyundai vehicles?▼
Common causes on Hyundai: Stuck or failed pressure control solenoid B, Low, dirty, or degraded transmission fluid, Clogged solenoid screen or valve body passages, Sticking or worn valve body components, Wiring or connector problem at the solenoid. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0776 on a Hyundai?▼
Repair costs on Hyundai range from $600 to $4,500, depending on the specific model and root cause.
