P0776 on Opel
Pressure Control Solenoid B Performance/Stuck Off
P0776 on Opel vehicles indicates pressure control solenoid b performance/stuck off. Au7o has documented this code across 1 Opel model — most commonly on Insignia. 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 Opel range from $150 to $2,500, 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
P0776 on Opel by Model
Opel Insignia(1 issue)
- Insignia A Aisin AF40 Harsh Shifts / Shudder2008-2017
The Aisin AF40 6-speed automatic in Insignia A (2008-2017) develops harsh shifts, shudder during lock-up, and delayed engagement, typically by 100,000-160,000 km. Root cause is degraded ATF and worn solenoids; Opel's "lifetime fill" claim is widely disputed.

What does P0776 mean on Opel?▼
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 Opel specifically, this code is documented across 1 model.
