P0868 Transmission Fluid Pressure Low

Transmission

P0868 means transmission line pressure is too low, which lets clutches slip.

The transmission computer measured line pressure lower than it needs to hold the clutches firmly. Low pressure causes slipping and fast wear.

Can I keep driving? Not if you can avoid it.

Drive as little as possible. Low line pressure lets clutches slip and burn.

Common causes

  1. Low transmission fluid from a leak
  2. A clogged transmission filter
  3. A failing transmission pump
  4. A faulty pressure control solenoid or sensor

Symptoms

  • Slipping, delayed engagement
  • Harsh shifts
  • Limp mode

What to check first

  1. Check fluid level and look for leaks.
  2. Check fluid condition; burnt fluid or debris points to internal wear.
  3. Check for pressure control solenoid codes.
  4. Have line pressure tested by a transmission shop.
