First off thanks for the continued responses and offers for help, I'm feeling much less alone in this battle!
I spent a good part of the day trying to sort out some of the above and here's where I netted out:
Knock Sensors - Per the service manual, attached
1. I tested both knock sensors and they came back within the correct resistance spec.
2. I ohm tested the wires from both plug ends (each sensor plug to PCM connector) and they checked out ok.
3. I put the car in key-on position, pulled off the PCM connector and tested the corresponding pin on the PCM itself for 5V and there was nothing. Then I plugged the connector back in and tested the same pin by using a piece of thin wire running down through the back side of the connector, still nothing.
The service manual says there should be 5V. If not, there's a circuit short or it's a bad PMC.
So that points to bad PCM?
Scan9495 - Data logging
Wow, this software is really great, I'll certainly make a donation! That said, for the life of me, I couldn't figure out how to record and save the transmission data. I checked the box in the transmission tab for dataloging, but i couldn't play it back. All of the datalogs I made today can be found here (the last one is probably the best): https://www.dropbox.com/sh/84hyxymk0...FtnKj3Rba?dl=0
Because I couldn't playback the trans data I made a video (https://youtu.be/ARK0Uh2pCxs) which should match the last of the data files in the dropbox if you sort by date/ time. I apologize in advance for the video quality. I'll try to stabilize it later when my computer isn't acting up.
The software seems to create two files (DLOG-trans... and DLOG-Save...). I can't open the "trans" file without getting a hex error. The "Save" files open but do not play back the transmission data. Confused yet? I am.
Transmission Observations
I jacked up the tail of the car and did the following:
1. (not in video) When shifted in Park and key-on, I was able to use the Actuator screen feature to actuate all the solenoids one at a time, in both directions. Or at least, I was able to hear them all make a clicking sound.
2. If you watch the video, towards the end, you'll see that I am able to use the command shift buttons to shift gears up and down successfully. You'll also see that sometimes I had to click more than once to get it to work, not sure if that's an indicator of anything.
3. Manually shifting the transmission does NOT change the gears.
Thoughts/ Questions
Given that the knock sensor 5V output pin on the PCM does not work, I'm led to believe I may want to replace the PCM.
I'm not sure what it means if I can command the transmission to shift up and down using 9495, but it refuses to shift manually.
Is that a PCM problem? i.e. The PCM is not sending the proper signal to the transmission.
Or the it a mencanical issue? i.e. The trans is in a mechanical state which will ignore an incoming signal.
Any thoughts?
