Welcome to this forum! I've moved your thread into the Aerostar section. If both A4LD transmissions are set up to be used in a 2WD, then it should be an easy swap. You already have the 3.0L bell housing. Both vehicles have a column shift, so the shift bracket is the same (although some brackets that are used on Explorers are slightly different from what I've read). The floor shift brackets are different. Either way, the brackets are easy to swap if necessary.
