Any 6l80 experts around?

[67Steven]

I am working on my l92/6L80 combo trying to get the trans to stop whining, and I may have tracked the culprit down, but need someone to verify I am reading it correctly.

According to this diagram http://www.lt1swap.com/pictures/6Lx0...p%20Signal.gif

1. The red/white wire 1840 should be hot at all times, correct?

2. Orange and black 6399 should be controlled by the ECM?

(Pin 59 I believe since I am not running a BCM and not a manual trans) If I do not connect this to the ECM, I get a CEL P2534 with 'lost trans signal' every time I start the truck and I have to clear it every time. I originally had the OG/BK wired to switched 12v, but kept getting the P2534 CEL.

I researched and found this video:http://youtu.be/SLGXIJNUwJ4 from this thread:https://forum.efilive.com/showthread...n-engine-swaps which led to the conclusion above. No more CEL.

Right now, the wires are reversed, OG/BK hot all times and RD/WH switched by ECM at the trans pigtail. Which leads me to believe that this is keeping the trans solenoid pack powered at all times when it shouldn't be, thus producing the whine.

I am wondering if by manually turning off (by battery or removing the trans pigtail) the trans signal to stop the whine, if it is not allowing it to do the adaptive learning for shifting?

Or, am I completely off base?

Thanks for any help!
