P2534 error

[Lennart]

On the second ignition cycle I will get this DTC on my L92/6L80E conversion.
Tested the voltage at the tranny, all seems fine.
For now I disabled the DTC processer in the tune, will try to hook up the BCM
next.
Has anyone come acroos this on conversions?
Once the DTC is set the tranny will not shift right. Clearing the DTC will work,
it will come back on the next ignition cycle, though.

I am having the same problem with my swap. I put a ly6/6l90 in my chevelle. I made my own wiring harness and I incorporated the bcm and gauge cluster. My trans not only shifts funny on the second start but also makes a grinding noise.
Have you found a solution or do you still have it disabled? Have you had any problems since disabling it? Any info and advise you can provide will greatly be appreciated

I still have it disabled, seems to work just fine. So far we have not added the BCM, though.
