Done a l98 /6l80e conversion but keep getting code p1825 in the tcm and is stuck in limp mode i ve swaped the range switch over -no good tryed a different tcm - same code, disabled code in tune and then we have no drive at all i noticed the tcm has a p/n out put on pin 3 i wonder if this needs to go to the ecm and then the ecm sends a signal back to the tcm via can bus?

Might be a mis-alignment between the transmission selector lever and the transmission range switch.

It feels like it dropps on to the gear nice against the detent i might drop linkage off to confirm they have modded the column selector to mate up to the 6l80e
