I have read and read and read on forums that all my "symptoms" sound like the TCM, I can order a used one for 65 bucks, for one through nissan here.

If I order a used one, and make sure part numbers all match, does it need to be reprogrammed at a dealer? Our symptoms are a hard "kick" when re-accelerating from slowing or a stop, and an occasional kick when it shifts, tho they are rare. Also have had one instance where the wife was driving, and received NO power to the wheels, rpm's everything like normal, she shut it off let it set for 2 hours or so, started and no issues except for the kick.

The kick is only after it has had time to run and "warm up".
