P0751 on Hyundai
Shift Solenoid A Performance/Stuck Off
P0751 on Hyundai vehicles indicates shift solenoid a performance/stuck off. Au7o has documented this code across 3 Hyundai models — most commonly on Azera, Genesis Coupe, Scoupe. This code means the transmission control module commanded Shift Solenoid A (sometimes called Shift Solenoid 1) but the transmission did not respond properly, with the solenoid acting as though it is stuck 'off.' Shift solenoids are electrically operated valves that direct hydraulic fluid pressure to engage gears, so when one underperforms the transmission may shift harshly, slip, or fail to change gears at the right time. The computer sets this code when the measured gear ratio or shift behavior does not match the commanded state. It generally indicates a hydraulic or performance issue with the solenoid or the fluid circuit it controls inside the automatic transmission. Typical repair costs on Hyundai range from $100 to $3,000, depending on the specific model and root cause.
Common Causes of P0751
- •Stuck or failed Shift Solenoid A
- •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 mechanical wear
- •Faulty transmission control module
P0751 on Hyundai by Model
Hyundai Azera(1 issue)
- Automatic Transmission Shift Hesitation and Shudder2006-2011
The 2006-2011 Hyundai Azera with the 5-speed or 6-speed automatic transmission develops shift hesitation, particularly a noticeable 1-2 shift delay under wide-open throttle when cold. The torque converter lockup clutch also develops shudder during light-throttle cruising at 35-55 mph. Hyundai issued a PCM recalibration procedure to address the cold-start hesitation. If the transmission fluid is not changed regularly, the shudder progressively worsens and can lead to torque converter failure or internal transmission damage. The Azera shares its transmission with the Sonata and Santa Fe of the same era.
Hyundai Genesis Coupe(1 issue)
- Concentric Slave Cylinder Failure (Manual Transmission)2010-2016
The concentric slave cylinder (CSC) in manual-transmission Genesis Coupes fails prematurely, causing soft or spongy clutch pedal feel and eventually inability to disengage the clutch. The internal seal leaks, allowing fluid to contaminate the clutch disc. Replacement requires transmission removal, making it a labor-intensive repair.
Hyundai Scoupe(1 issue)
- Automatic Transmission Premature Failure1991-1995
Like its Excel sibling, the Scoupe automatic transmission suffers from premature wear and failure. The same 4-speed automatic unit is used, with identical failure modes including clutch pack degradation, valve body issues, and torque converter problems. The Scoupe Turbo model puts additional stress on the already marginal transmission. Manual transmission models are far more reliable and the preferred choice among enthusiasts.

What does P0751 mean on Hyundai?▼
P0751 stands for "Shift Solenoid A Performance/Stuck Off." This code means the transmission control module commanded Shift Solenoid A (sometimes called Shift Solenoid 1) but the transmission did not respond properly, with the solenoid acting as though it is stuck 'off.' Shift solenoids are electrically operated valves that direct hydraulic fluid pressure to engage gears, so when one underperforms the transmission may shift harshly, slip, or fail to change gears at the right time. The computer sets this code when the measured gear ratio or shift behavior does not match the commanded state. It generally indicates a hydraulic or performance issue with the solenoid or the fluid circuit it controls inside the automatic transmission. On Hyundai specifically, this code is documented across 3 models.
What causes P0751 on Hyundai vehicles?▼
Common causes on Hyundai: Stuck or failed Shift Solenoid A, 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.
