Got Redline D4 for my 04 Honda Accord w Auto trans. Did some extensive reading about product on various forums and what not prior to deciding to give it a shot. I'm a big fan of Hondas, but if you're looking at this stuff for your Honda you already know all about the transmission issues. And you probably already know that most people tell you to only use z1 or the new dw1 fluid from Honda. I had a 2000 accord prior to this one, bought it used and did the trans drain and fill 3 times w dw1- 5k miles later I had trans issues. Maybe the fluid, maybe not. Car had 190k. My 04 has 130k and I just purchased it used. When I initially drove it I didn't notice anything with the transmission, but the more I drove it I started to notice a bit of a long shift from first to second, and a bit of gear searching from time to time in the city. I knew the fluid was a little dirty and my first step when I buy a used car is to change oil, trans fluid, diff fluids, power steering, etc. so that tells you a little about my maintenance habits w vehicles and my attention to detail. I only use Mobil 1 synthetics religiously but their ATF Fluid wasn't necessarily "recommended". So I decided to give this Redline a shot. I must say, I haven't driven many miles yet (500 or so) since the change, so time may change my mind. However, with how auto trans work you can usually tell almost instantly if you have a fluid that isn't compatible with your car. Slipping, weird shifting, etc. I am really pleased with the results of the Redline ATF though. I immediately notice little to no gear searching, and the 1-2 shift is much better. Overall the shifts are still smooth when I'm just taking my time, and very quick and precise if I'm giving a little more gas. Granted my fluid was ready for a change, but I think the Redline improved my cars shifting more than new Honda fluid would have. I've seen both results in different cars. I did a 4 x drain and fill using 12 qts of Redline to get as much old out as I could. My advice, forget Honda fluid and buy this Redline. It's a much better fluid. It's synthetic. It works great, and seems to be completely compatible with Honda's fragile transmissions. In my opinion it's the best precaution you can possibly take. I'm really pleased with the results. As I said before, time could change my opinion but I don't expect it to. Synthetic fluids run cooler, don't break down as easily or as quickly, last longer, etc. I plan to drain 3 quarts and fill at every 5k oil change. Overkill? Maybe. But if you own a Honda and are looking at Redline fluid you know why I'm taking the extra precaution.

Works great in my BMW Z3, only need 1 quart.

I read reviews elsewhere that this stuff smooths the shifts so I tried it. I recently acquired an old classic car with auto trans. It’s known to shift more abruptly than a modern car. After changing to this stuff, the shifts were noticeably smoother right away. Really works.
