Red Line Synthetic Automatic Transmission Fluids are designed to provide excellent low-temperature shiftability and improved thermal stability over petroleum ATFs. These fluids provide a much lower viscosity at cold temperatures for quicker shifting and their balanced frictional characteristics provide smooth and consistent shifts over extended drain intervals. The superior stability compared to petroleum ATFs also allow high-temperature operation without varnishing valves and clutches, which leads to transmission failure.

By Mr. Perry on September 19, 2022
My car was starting to shutter (maybe slip?) when I was going steady at ~55mph and the engines rpms were low (presumably 4th gear, it's a 4 speed automatic). It wouldn't do this if I stepped on the gas and the car downshifted.
After flushing my tranny with this fluid, that shuttering has not happened. Also, my first and 2nd gear shifts are MUCH smoother, sometimes they can only be noticed by watching the tachometer.
I have driven about 4k miles since flushing my transmission, and I haven't had any more wonky transmission behavior!!!
How I did it/instructions for the Mazda Tribute 2003 (same for Mercury Mariner and Ford Escape ~2002-2006 I'm not 100% sure of those years):
I connected the fluid output of the transmission (going to the radiator) to a 3/8" ID fuel hose and put the other end of the hose in a 5 gallon bucket. I poured in 12 quarts in with the car running and in park. When I started the car it gushed out ~4 quarts. As you add more it flushes more out. This is how I have seen it done in many YouTube videos, hopefully it is flushing the old stuff out! I would think it would have to be. Anyway, after adding 12 quarts and letting it empty itself until it couldn't anymore, I turned off the car, reconnected the output of the transmission to the radiator, and topped off the sump area (3-4 more quarts were need). I drove around a bit, came back and checked the level. I used my manual for further instructions on perfecting the transmission fluid level (this is equally important if not more important than having fresh fluid!!!), and one week later I drove 1 hour to my parents' house, parked in their garage (you want a surface that is almost perfectly level. A small grade makes a huge difference in my car!) And with the engine hot, running and in park I checked the fluid. I needed to add a bit more. You want to actually drive at decent speeds before checking your fluid. If you let it idle for a long time it gets hotter than it would be if air is constantly flowing through the radiator! What I did was I turned my car off when I got to my parents house, got ready in about 1 minute to check the level and add fluid if necessary, started the car again (didn't want to run it for that minute for fear that I would further heat the fluid and get a false reading), and then I checked the level, added, checked, and added again until it was 1/3 up the hashed area. The dipstick says not to add more if it's in the hashed area. I wanted it to be at least 1/3 of the way up since I had driven on a cold day.
Hope this review helps!!
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.
