Generic OBD-II
Medium
What it means
P2722 flags a fault with transmission pressure control solenoid E, which regulates the hydraulic pressure applied to a clutch or circuit during shifts. It's usually a solenoid, wiring, or valve-body issue, sometimes tied to low or dirty fluid. The car still drives, but shifts may turn harsh or slip, and it can drop into limp mode.

How to diagnose & fix
Work through it in order
- Check transmission fluid level and condition first.

- Inspect the valve body; replace the solenoid if faulty. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P2722?+
Usually short-term, but pressure control problems cause harsh or slipping shifts that add wear. Have it diagnosed before it worsens.
Can I just clear P2722?+
It returns until the solenoid or its wiring is repaired. Clearing alone won't restore proper shift pressure.
