P2714 Code: Pressure Control Solenoid 'D' Performance/Stuck Off
Transmission pressure solenoid D isn't regulating pressure as commanded – a classic source of harsh shifts.

Modern automatics set their hydraulic pressures with variable-force solenoids that the transmission computer drives with a precisely controlled current. On Toyota's Aisin-built U660E and U760E six-speeds, pressure control solenoid D is the SLT solenoid, which sets line pressure for the whole transmission; on other units, D may control a single clutch. P2714 is a performance code, not a wiring code: the circuit tests fine, but the transmission behaves as if solenoid D isn't doing its job – shifts that are too quick or too slow, slip where there shouldn't be any, or a pressure switch that disagrees. 'Stuck off' on a line-pressure solenoid means pressure stays near maximum, so engagements into Drive and upshifts, especially 1-2 and 2-3, bang hard. Sticking from wear debris in the fluid and worn valve-body bores are the usual reasons.
Can I keep driving? The car usually drives, but harsh engagements and bangs on shifts wear clutches, mounts and driveline parts. Drive gently until it's diagnosed and have it checked promptly if it goes into limp mode or starts slipping.
How to read P2714
- P Powertrain
- 2 Generic (SAE)
- 7 Transmission
- 14 Specific fault
Symptoms
- Hard clunk when shifting into Drive or Reverse
- Harsh, banging 1-2 and 2-3 upshifts, often worse once the fluid is warm
- Flare or delayed engagement on some shifts
- Check engine light, sometimes with a flashing O/D or transmission warning
- Transmission holding one gear in limp mode
- Slipping feeling under light throttle in some gears
Possible causes
Ranked by how often each cause is behind this code (editorial estimate).
- Pressure control solenoid D (SLT on Toyota) sticking from varnish or wear debris
- Worn or contaminated fluid, or low fluid level in a transmission without dipstick
- Worn valve-body bore or sticking pressure regulator valve
- Clutch wear causing ratio errors the computer blames on the solenoid
- Outdated transmission software or corrupted adaptive values
- Intermittent wiring or connector issue not severe enough for an electrical code
Diagnosis step by step
Check fluid level and condition correctly
Many of these transmissions have no dipstick; the level is checked at a fill/overflow plug with the engine idling and the fluid within a narrow temperature window – on Toyota U660E/U760E roughly 95 to 113 °F. Dark, burnt-smelling fluid or glittering particles change the whole diagnosis.
Tools: OBD-II scanner, Towels & shallow pan
Look at commanded solenoid current and shift data
In live data, compare the commanded current to solenoid D with fluid temperature, throttle and shift times. A command that changes normally while the shift feel doesn't respond suggests a sticking solenoid or valve rather than a control problem.
Tools: OBD-II scanner
Run a line pressure test
Connect a pressure gauge to the line pressure test port and compare idle and stall readings in Drive and Reverse with the manufacturer's specification. Pressure that stays high at idle confirms a line-pressure solenoid that isn't reducing pressure.
Check for software updates and reset adaptives
Ask a dealer whether updated transmission calibrations exist; several have been released to improve shift quality on Toyota six-speeds. After any repair the learned values must be reset so the computer doesn't keep compensating for the old fault.
Tools: OBD-II scanner
Drop the pan and inspect
Look at the magnet and pan bottom: fine grey paste is normal wear, but large metal pieces or lots of friction material point to internal damage. On Toyota U660E/U760E, the SLT solenoid is on the valve body and can be reached once the pan is off.
Tools: Towels & shallow pan, Torque wrench
Replace solenoid or valve body
With clean fluid and no major debris, a new solenoid D usually cures the harsh shifting. If the valve body bores are worn, a new or remanufactured valve body with solenoids is the lasting fix.

Notes by brand
Toyota
P2714 is a well-known code on the U660E and U760E six-speed automatics used in the Camry, RAV4, Highlander, Avalon and Sienna, usually with harsh 1-2 or 2-3 shifts. A sticking SLT solenoid is the most common cause; a software update, fresh WS fluid and, if needed, a new solenoid or valve body typically resolve it.

Emissions / smog test impact
Will fail
On most vehicles P2714 turns on the check engine light, so the car fails an OBD smog or emissions check. Reset the adaptives after the repair and drive until the monitors are complete.
Frequently asked questions
Is P2714 an electrical problem?
Usually not. The circuit for solenoid D is fine – that would set P2716 instead. P2714 means the solenoid or the valve it controls isn't producing the expected result, which is almost always mechanical or fluid-related.
Will a fluid change fix it?
Sometimes it helps, particularly when the fluid is old or low, because fresh fluid can free a lightly sticking solenoid. If the shift quality doesn't improve within a few days of driving, the solenoid or valve body needs attention.
Can harsh shifting damage the transmission?
Over time, yes. Excessive line pressure slams clutches on, loads mounts and axles, and can crack or wear parts. It's worth fixing even if you've got used to the bump.
Why is it called 'stuck off'?
It describes the solenoid's output, not the valve's position. With a line-pressure solenoid 'off', the transmission defaults to high pressure – that's why the symptom is harshness rather than slipping.
