I think it might be the USDM accords that mainly have transmission issues. Mine is the USDM version but I looked up my VIN and my car was 100% assembled in Japan. There were only about 30% or so that were assembled in Japan. My tranny has about 138.4k and I beat on it from time to time and so far it's fine. However, I do have a tranny cooler and I change my fluid ever 10-15k. Last time I changed it, I used DW-1 and it seems to be working nicely until it started to blend in with the Z1. Planning on doing another DW-1 drain and fill this weekend. Hopefully it'll get most of the Z1 out of there. Also, I warm up my car everyday before I drive it and when I park, I put it in neutral first, e-brake up, left off the brake, and put it in park. Rear brake pads are much cheaper than a brand new transmission rebuild.
