I know of no reset, did you check all of your wiring, especially by the starter? Remove the crank position sensor, was it installed correctly? What are your symptoms, does the car crank at all, do you have clicking indicating a discharged battery?

It cranks but there is no power to the computer and the sparks plugs.and it sounds like the fuel pump is not getting fuel

So the fuel pump doesn't buzz/prime when you turn the key? Sounds like something isn't connected electrically. When you replaced the transmission did you disconnect the battery? I would start pulling fuses to see if any are blown.

Dme problem. Trace power from fuse . Then check if u have the same voltage going to dme, .
