P2828
Pressure Control Solenoid K
Transmission
Generic OBD-II
Medium
What it means
P2828 flags a fault with transmission pressure control solenoid K, which regulates hydraulic pressure for a clutch or shift element. The problem is usually electrical — a failed solenoid, wiring, or connector — or the result of low/dirty fluid. It typically shows up as harsh or erratic shifting and can put the transmission into limp mode until repaired.
Medium
Can I keep driving? Drivable with care — shifting may be harsh or the transmission may drop into limp mode; have it checked soon.
Common symptoms
What you'll notice
- Harsh, delayed, or erratic shifts
- Transmission slipping or not engaging a gear
- Limp mode (stuck in one gear)
- Check-engine light on
Common causes
Most likely first
- Failed pressure control solenoid KLikely
- Open or short in the solenoid K circuitCommon
- Damaged wiring or corroded connector at the solenoidCommon
- Low or dirty transmission fluid affecting solenoid operationLess often
- Valve-body or transmission control module faultLess often
How to diagnose & fix
Work through it in order
- Scan and read freeze-frame data to confirm the solenoid and conditions.
- Check transmission fluid level and condition first.
- Inspect the solenoid K wiring and connector for opens, shorts, or corrosion.
- Measure the solenoid's resistance and command it with a scan tool.
- Replace the solenoid or valve body as needed, then clear and re-test.
FAQ
Quick answers
Is it safe to drive with P2828?+
Short, gentle trips may be possible, but harsh shifting or limp mode makes it unreliable. Have it diagnosed before extended driving to avoid further transmission wear.
Can I just clear P2828?+
It will return once the solenoid K circuit or performance is evaluated again. The underlying solenoid, wiring, or fluid fault must be repaired.
