Hello, although before now while driving it will engage and disengage at either 3 or 4 and engages again. When the vehicle is scanned the codes found in its memory was " pressure control solenoid D Electrical".
I have checked all the wires at the transmission to it PCM for continuity, they all pass.
I want to check for the exact solenoid, but I don't know it. I don't know if I can have a diagram for this and how would I know that it is not the PCM that has issue?
Could I get road test manual?

Good morning,

I attached the location of the solenoid for you. It is in the valve body and the pan must be removed to gain access.

Could you please post the code number for me so I can get the exact flow chart for the code to be sure it is the solenoid?

I attached the possibilities and the flow chart for you to follow to see if it is a wiring or if it is either the ECM or a shift solenoid.

Good morning, sir, from the diagnostic chat, there is none referring to the ECM, what it is the ECM that has issue?
What test could be carried out?

The ECM is what controls the opening and closing of the solenoids by grounding or ungrounding the return wire from the solenoids.

If it is not doing that, then it is the issue.

There is no testing without special equipment for this.

It is working correctly now after the pcm has been replaced. This is one of my concerns, for someone to know that the problem is PCM
