P0751 on Kia
Shift Solenoid A Performance/Stuck Off
P0751 on Kia vehicles indicates shift solenoid a performance/stuck off. Au7o has documented this code across 1 Kia model — most commonly on Amanti. 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 Kia range from $1,500 to $3,500, 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 Kia by Model
Kia Amanti(1 issue)
- Automatic Transmission Failure (5-Speed)2004-2009
The 5-speed automatic transmission in the Kia Amanti is prone to premature failure, particularly affecting the torque converter, forward clutch pack, and valve body. The transmission was shared with the Hyundai XG350 platform and struggles with the 3.5L V6 engine torque output. Symptoms progress from harsh shifting to slipping to complete failure, typically between 80,000-120,000 miles. Regular ATF changes can extend life, but the transmission design has inherent durability limitations.

What does P0751 mean on Kia?▼
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 Kia specifically, this code is documented across 1 model.
What causes P0751 on Kia vehicles?▼
Common causes on Kia: 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.
