The P0730 code on Honda's can be caused by a few different things. If the car is performing properly, ( smooth shifts up and down) it's not internal. I have seen this code pop up when the engine was running hot, overheating the trans. fluid which in turn causes the torque converter to slip. The other is worn out transmission fluid. Check and fill the radiator, then do a dump and fill of the transmission. Get yourself 4 qts. of Z1 transmission fluid from the dealer and change the trans. fluid. While the car is up, check the electrical connectors at the transmission as well.
