360 46RE driveline swap, wont shift

Thanks for all of the replies! I know too well about getting bad "new" parts. Again, no problems here re-checking stuff. I'm getting old and have been known to overlook the simplest of things :lol:
This ended up being a little odd.
I ended up going all the way back through the wiring, cleaning the solenoids, new filter and fluid and it works. Shifts nice and firm AND where it's supposed to shift.
The goofy thing is that I'm not really sure what the issue was. All I did was a very light cleaning and since the pan was off I replaced the filter...and the old one didn't look all that bad.

So, the only things the PCM needs to be able to shift the RE trans is the 8-pin ( routed properly back to the PCM) , output speed sensor ( the white one in the trans ), the trans relay ( to power the 8-pin ), and the throttle valve cable.
I'm sure that it also needs the throttle position sensor and some other sensors from the engine, but it's really that simple :lol:
