Answer
Could very well be the TCM. Have you scanned the vehicle for any transmission codes, any shift solenoid problems? I would put a scanner on the vehicle if possible- should be free at any auto shops. See if they will check the trans data stream and make sure the TCC is cycling like it should. I would do that before having a trans flush, esp if you have 100k miles and not had a trans flush done in the past could cause problems. yes you need Honda trans fluid- not dexron or mercon. Nissan also has there version of a j-matic fluid. i belive its ATZ-f1 you need. I would double check before adding any. check the trans with a scanner if you haven't done it yet before you spend money on flushing the trans. when you changed the fluid did you do a drain and fill? you might have put wrong fluid in. If your gonna flush it again take it to a shop and have a flush done with a machine. by doing a drain and fill your only really getting about 4 quarts out. a flush will clean all 10 plus quarts in all the lines a Torque converter cleaned out well.
