P2715 Pressure control solenoid D stuck on

Pressure control solenoid D stuck on

P2715 in short

P2715 means the computer sees pressure control solenoid D staying on when it should be cycling, so hydraulic pressure is not regulated properly. A faulty solenoid is the main cause, with dirty fluid and valve body faults behind it. Slipping, harsh shifts and overheating are possible; get it checked promptly.

Pressure control solenoids set the hydraulic pressure that applies clutches. Solenoid D is one of them.

If the computer sees it stuck on, or pressure higher than wanted, it sets P2715. This can cause harsh shifts, slipping and heat.

PartsAvatar rates it serious: continued driving risks damage that is far costlier than a solenoid.

Most likely causes

These are general causes for this code across vehicles. None is specific to one make or model.

  1. Pressure control solenoid D stuck on

    Common general cause
    Why it ranks here
    The code is about this solenoid, and both references list a faulty solenoid first.
    What would change this
    Rises if the solenoid does not respond to a command or pressure stays high. Falls if it cycles normally.

  2. Low or dirty transmission fluid

    Common general cause
    Why it ranks here
    Several of the cited references list a wrong level or contaminated fluid among the first things behind this kind of transmission fault, and it is also the cheapest thing to check.
    What would change this
    Rises if the fluid is low, burnt or contaminated. Falls if the level and condition are correct.

  3. Defective valve body or blocked passages

    Possible — needs testing
    Why it ranks here
    PartsAvatar lists the valve body and fluid blocking passages; TroubleCodes.net lists mechanical faults.
    What would change this
    Rises when the solenoid tests fine but pressure is still wrong. Falls when the solenoid is faulty.

  4. Damaged wiring or a corroded connector

    Common general cause
    Why it ranks here
    The cited references list damaged wiring or poor connections in the circuit as a common cause, and the fault is electrical in nature.
    What would change this
    Rises if a scan tool shows an intermittent signal or a connector shows corrosion or damage. Falls if the circuit tests normal.

What to test first

Start at step 1. Each result tells you what it means and where to go next.

  1. Read every stored code and freeze-frame data.

    Low riskTool: scan tool that reads the transmission module

    • IfOther transmission codes are stored with it

      It meansWork from the first code stored, since one fault can set several.

      Go to step 2

    • IfIt is the only code

      It meansCheck the fluid and the wiring next.

      Go to step 2

  2. Have the transmission fluid level and condition checked, following the maker's procedure for your model.

    Best left to a shop

    Warning:Many transmissions are checked hot with the engine running, and some are sealed with no dipstick. Let a shop do this.

  3. Have the wiring and connectors for the circuit inspected and tested, and ask whether a software update exists for your VIN.

    Best left to a shop

    Warning:Testing circuits and software updates need shop equipment; let a shop do this.

Symptoms

  • Check engine light
  • Harsh gear shifts
  • Transmission slipping
  • Transmission overheating
  • Engine stalling on some vehicles

How to fix

  1. Have a shop scan the transmission module for every stored code and freeze-frame data before any parts are replaced.

  2. Ask a dealer or shop whether a transmission software update or bulletin applies to your VIN.
