Drivable short-term, but fix now to avoid damage.
This code is set when the pressure control solenoid isn't responding correctly or seems stuck in the off position, so the transmission can't properly regulate hydraulic pressure. It often points to a failing solenoid, but low or degraded fluid and wiring issues can also be the cause. Fixes commonly involve a fluid service, replacing the solenoid, or repairing the electrical connection.
$250 – $900
Varies by vehicle and root cause.
Short trips are usually possible, but it isn't ideal. The transmission may shift harshly or limit itself to fewer gears, and driving this way can wear internal parts faster. Get it diagnosed promptly to avoid bigger repairs.
A fluid and filter service may cost around $250, while replacing the pressure control solenoid usually falls between $400 and $900 including labor. The price depends on how deep in the transmission the solenoid sits.
It should be taken seriously. A stuck-off solenoid disrupts pressure control, which can lead to slipping and clutch damage over time. While the fix is sometimes simple, ignoring it risks a much costlier transmission repair.
It means the solenoid isn't engaging when commanded, so it can't reduce line pressure as needed. This often leaves pressure too high, causing firm or harsh shifts, and usually points to a failing solenoid or fluid restriction.
