Got a 2004 sedona 3.5 just put a junk yard motor in it out of an 02 and got everything bolted back up and started motor and all went well put tranny in gear and nothing. Hubs will not turn at all no matter what gear its in. Lost about 2qts approx during change over and put 2 back in. showing plenty of fluid on dip stick and still nothing. Changed ISC from old motor to new after researching site and still nothing. Any help or ideas would be greatly appreciated. Also does the ECM need to be reflashed to make everything work right with new motor?
