Yeah, ive never seen the alternator do anything to the transmission but if you start missing power to the computer systems on the vehicles now, it will definately make stuff act weird. Also, I see alot of problems that come in to the shop where scanning the Powertrain Control Module doesn't even help. Or any of the computers on the vehicles. I would check connections at the computer looking for water intrusion of some sort.
