Transmission p2716 pressure control selenoid "d" electrical

P2716 Pressure Control Solenoid 'D' Circuit Malfunction
Possible Causes Setting Conditions

• Shift solenoid (SLT) connector is damaged (check pins for damage, moisture)
• Shift solenoid (SLT) control circuit is open or shorted to ground
• Shift solenoid (SLT) has failed (electrical fault)
• ECM has failed the solenoid is under/ behind the transmission pan

jack up the car and check each wheel to see if the the breaks binding

code p2716 refers to transmission fluid pressure (TFP) solenoid D --electrical=== causes wiring---TFP solenoid
check all connections are clean and tight . replace the solenoid.

P2716 -Pressure Control Solenoid "D" Electrical (Shift
Solenoid Valve SLT)
Trouble Area:
1. Open or short in shift solenoid valve SLT circuit. (repair harness wiring)
2. Shift solenoid valve SLT defective. (replace)
3. ECM defective. (replace with a good known one)

have the code checked especially if the car is out of warranty. If it is still under warranty take the car to the dealership . The Pressure Control Solenoid determines the quality and accuracy of the shift points and if you let it go the transmission will not shift properly after a period of time. The pressure control solenoid is used by the PCM to raise the mainline hydraulic pressure during high throttle - this increases the holding force on the clutches and bands and prevents slipping. The pressure control solenoid is controlled by pulses from the PCM and this in turn operates the boost valve insde the valve body.

The problem could be either in the PCM or it could be an electrical problem with the solenoid. As suggested it should be diagnosed by a transmission tech. They can check if the PCM is good by looking at the pulses with an oscilloscope at the connector and they should also be able to test the continuity of the solenoid. If the solenoid is faulty the valve body will need to be removed and the solenoid replaced.
good luck

P2716 Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT).

There are 3 things it could be.
It could be your ECM, shift solenoid valve SLT, or open or short in the circuit. I would just recommend saving the hassle and taking it to an ASE qualified mechanic.
Here is what is happening...
The linear solenoid valve (SLT) controls the transmission line pressure for smooth transmission operation based on signals from the throttle position sensor and the vehicle speed sensor.

There is a Bulletin on this concern, and it is a warrantable condition for 8 years or 80,000 miles so you are still covered by the factory warranty.
The problem is a logic issue in the PCM. The correction is a new PCM with updated software.

TRANSMISSION & CLUTCH
TC015-07 Title:
HARSH SHIFT AND M.I.L. "ON"
DTC P2716 Models:
'05 - '07 Corolla & Matrix (1ZZ-FE) September 20, 2007

Introduction
Some 2005 - 2007 model year Corolla and Matrix vehicles equipped with an automatic transaxle may exhibit a harsh shift condition and a M.l.L. ON" with DTC P2716 stored.
Improvements have been made to the Engine Control Module (ECM) (SAE term:
Powertrain Control Module/PCM) to reduce the possibility of this condition occurring.

Applicable Vehicles
^ 2005 - 2007 model year Corolla and Matrix (2WD) vehicles equipped with the 1ZZ-FE engine.
Warranty Information
Applicable Warranty*:
This repair is covered under the Toyota Federal Emissions Warranty. This warranty is in effect for 96 months or 80,000 miles, whichever occurs first, from the vehicle's in-service date.

This is most likely due to a bad solenoid pack in transmission. You could have tranny serviced and see if it helps. Poor fluid condition makes valves stick in those.

P2716 relates to the pressure control solenoid "D" electrical circuit. I think it's with the transmission. I will research it more.
