No start after trans swap, code u1016

[henry2255]

03 Denali, 6.0 AWD... I swapped in a 4L60e from a truck, because I couldn't find a 4l65 anywhere. Now the truck wont start.
Things I have checked already:
Fuel pressure is good
Checked and cleaned grounds and all connectors
Checked every fuse and tested every relay
There are no pinched wires anywhere
The upstrem 02 on the drivers side had bare wires, I repaired it.

There is no spark. At all. It'll crank for 45 years and still not start. The only.code im getting is u1016. Anyone have any ideas?

There is no difference between a 60/65 except 5 pinion planetary gears.

You sure you didn't pinch any wires? Between the bellhousing and block?

There is a small ground wire for the coils that bolts to the block behind the power steering pump. Usually that fixes my no spark issue... Is the crank sensor plugged in? Plug not damagedz etc?
