Output shaft speed sensor?

Let's step back and look at the code that it is setting. Let me know what code it is and we can get some more detailed info about the possible causes. Most solenoid codes could be the solenoid, wiring, or control module but again, let's get the code and go from there. Thanks

Okay. That is the torque converter solenoid and I attached the testing for it. Basically it could be the solenoid but there is also a possible wiring issue or even the PCM. The only way to know is to perform this testing.

Let me know if you have questions but I would run through this testing or have someone run through it because replacing solenoids only to find out it didn't fix it is not desirable. It is one thing if it is a sensor that is easy to get to but this is not the easiest job to "guess" at.

Okay. If they have all been replaced then that pretty much leaves a wiring issue. If you look at the last few pages of the testing that I provided it goes through what tests need to be performed.

Let me know if you have questions but we need to test for an open circuit, short to power or short to ground.

Good morning.

I attached a picture for you to view. Very easy replacement. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Hi,

It is located on the rear of the transmission.

Here are the directions for replacement. The remaining pics correlate with the directions.
