I know this clunk same thing happened to me, also i learned the front end needs an alignment everytime the front trans cradle comes out and back in.All this info compiled together is great. Thank you!
My EX kept "clunking" when I would take off in Drive and sometimes when turning a corner. I complained about this off and on for 3 years. They would tighten the struts and the problem got better for a little while and would start again. As I was nearing the end of my extended warranty, I insisted they fix the problem. Honda replaced both struts and it still did not stop. I had the mechanic ride in the car to experience it first-hand. After the very first clunk he asked if I'd had the transmission replaced. I said yes and that the noise started shortly afterwards. Apparently the suspension was not seated properly after the tranny was put back in. He made the necessary adjustments and I've not had a clunk since then. Just something to keep in mind if you're hearing clunks from the front.
