Thanks for the help. Intermittent automatic transmission sometimes it wont move in any gear.
It was almost a pint low. I added 12 ounces and so far so good. I will take out around town as soon as I can. My shifter worked as designed prior to the motor swap but you never know.
Yes,,the shifter could be out of adjustment a little now .
It might be almost out of position depending on how the detents align up ?
And with a Mopar with a short pan,,,a pint makes a big difference sometimes .
Actually,,,12 ounces is almost a quart,,, and the dip stick could be a little bit off as well .
I hope it fixes your problem .
Good luck .
Edit:
That is a beautiful shifter by the way,,,Awesome !
