From what I can find this code has something to do with the gear selection.
I don't know what I missed but its taking this thread off track, my apologies. I'm going to have to do somemore homework, I feel this is something simple that I moved on the valve body.
I also never did opened the valve body, only changed the solenoids and seals.

The TCU comms is actually a good thing. I googled that code.

The good news is that it is a generic code, and I suspect it is what is keeping the car from starting. Here is why. From that page:
"The Transmission Range Sensor is also sometimes called Park/Neutral switch or Safety switch. It communicates with the vehicle's transmission control module and PCM, and is attached to the manual valve of transmission."
It also indicates this for a possible fault which I think it helpful: "Faulty manual shift valve linkage".
Here's why.
Look at this doc and pics on page 6.

Did you verify your selector valve alignment was correct? I have an M-shift and I suspect you do as well, and you have to make sure it lines up correctly as you install the bolts (the lever should have been left in Park and you align the rod, lever, and the plastic piece when you bolt up the valve body). I suspect if this isn't correct, the car won't know you are in Park...which I believe is what the code is saying, if I am reading it correctly. Unfortunately, you will have to drain and remove the pan to check. I bought a new plastic gas container and used it for reclaiming my ATF when I was dealing with my issue so it would l be a less expensive decision to drain and refill. 
HTH and YMMV. |
I agree. See this....
