0x00008D IKE: EGS signal line disturbed [solved]

[aureliusmax]

UPdates: Requested a return for the replacement valve body as it's the wrong one, As per RRPhil.

To do:
remove the new valve body from the transmission, and install my old unit.
buy and install a genuine bmw transmission filter, as per RRPhil claiming often times secondary brands can have the filter element sucked inside.
measure all the solenoid and pressure regulator resistances in my existing valve body for reference.

determine the canbus waveform and voltage specifications for my vehicle. start to troubleshoot the circuit and remove modules connected to the canbus until the poor signal / issue can be identified.

update the graphic in the previous post with correct pin numbers and resistances for resistance tests.

I have not been able to make any progress on this issue, very frustrating and this is the first time i feel like I've been defeated as a mechanic, don't know what to do next except park this thing in storage. need to know for sure before sinking money on any replacement part. I absolutely, 100% and for a fact need to pinpoint the issue. Going to try these 'expert for hire' auto mechanic websites, and get a mobile bmw tech who can give a second opinion on the issue.

I did make some notes from my weekend work attempting to give one last try at troubleshooting before having to move the vehicle to storage lot.

Dispite any other code, this one is the issue and is either caused by another code, or this code causes the EGS module to lockout and not sent power to the mechatronics and throw a fit.
0x00008D IKE: EGS signal line disturbed

Tried in sequence order to disconnect other modules on canbus, clear codes, restart car, failsafe mode message appears, and then re-scan for codes.
Disconnected: EGS, IKE, and DSC/ABS I didn't try to disconnect the DME, I didn't think of doing that because how would I start the engine.

I will try it down the road but for now I need the community here to come together and give me their opinions.
