Check the crankshaft position sensor. It's located on the bellhousing and should have been replaced when swapping trans, only because it can be damaged or misaligned when doing the swap. It sounds like it's shorted. It may have damaged the transmission controller as well.

I would look for pinched wires around the bellhousing. It crapped out after the transmission was replaced? That should be a clue.
