I'm more than sure that it is the transmission pressure plates. Same problem with my prelude until I got the auto trans rebuilt. It will be a heavy grand or more to rebuild the transmission.
Whenever my D4 blinks, I just shut off the car and turn it back on. The check engine will still be there, but D4 does not blink anymore.

Your best bet would probably just get a 5 speed swap, as this will be the answer you will receive the most.
On the other not, just take it to a transmission shop and get a free estimate.

i had my tranny rebuilt. waste of time and money. though it has never gotten as bad as it was before its still running pretty bad. i suggest the 5 spd swap im looking into one for myself now.

experienced this ..alot spent 2500 dollars on getting it rebuilt. it lasted a year before dying again. then broke down 2 more times after. covered under warranty. keep in mind after the 1st time it broke i babied it and added a tranny cooler.

i ended up getting a 5 speed swap 2 months ago, best mod ever. a 5 speed lude will pull on an auto 5th gen with i/h/e/p. ( personal experience)

tl:dr
fixing the auto trans will just break again, get it swapped its not much more
