I lost all forward gears in my transmission, reverse works perfectly fine. It was showing the code for the slt solenoid P2714 so we replaced the solenoid. After getting everything installed again the transmission still wasnt engaging any forward gears. We disconected the computer and manually shifted the transmission and all the gears seem to be working but with the computer conected its as if we never fixed anything. After conecting the input speed sensor the same code for the SLT solenoid showed back up and its a brandnew solenoid. What am i missing or not seeing that could fix this issue???
Code p 2714 refers to transmission fluid pressure (TFP) solenoid D-performance problem or solenoid stuck off===causes --wiring---TFP solenoid--transmission mechanical fault
with the shifting of the gears manually , that rules out a mechanical problem
question now --did you replace the correct solenoid
did you check for faulty wires at harness connections or at the box
I would talk with an accredited auto transmission shop to identify solenoid D on your transmission and to see if there are any problems that occur on a regular basis in that area of the transmission ( wire insulation breaking down in the auto oil , problem solenoids etc
My bad. I was thinking of a different code when I wrote this. I was getting a code for the line pressure before we replaced that.
Could the compiter itself habe anything to do with the issue at all
the item that has control of the transmission is the TCM it reports to the ECM as to road speed turbine rpms so that the ecm knows when more power is required for a ratio change or when to change the mixture for down shifting
Could be the ECM but at this stage I would concentrate on the transmission controls and wiring
although you wrote the wrong code , the PTF solenoid can play a part in ratio selections

Sounds like the valve body is loose, warped or blown

Sam,
I would start with a transmission fliud and filter service.
I would then have the trasnmission checked out by a transmission shop. The transmission most of the time has the direct drum band is starting to go. The shops can rebuild it no problem, This is a very common failure wiith the trasnmission.
Good Luck

not sure if this is the answer yet but i have the same problem with the same codes i work at an auto parts store and a few of the techs that are customers have lead me in the direction of changing the ignition switch, i am doing it today will let you know if it solves the problem

DTC P2716 - Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT)
If you need to test this electrical components and wiring. Tell me if you need the TSB about this DTC.

i had the same thing with my neon.i replaced both input and output sensors and the ****** filter plus the dash consol.i also cleaned all my contacts on my plugs.none of that worked.i had a mechanic looked at it and he said i had a short in my harness,what a mess!one day i messed with the fuse pannel under the hood and decided to switch the relay on the atx with the horn and it ended up working.
