I’ve used this in many applications .My hondas absolutely love it .I have been able to totally change they way some automatics feel ,shift ,and stay cool .I was able to bring a chrysler 300c transmission back from slipping in every gear with this magical red juice .I use it for lip balm because it smells so good.I swear buy it and only use this on any transmission I service because it will last and perform every time .I will add Lubeguard on any drain and fill I do .I have used all the OEM fluids in differant applications and this will outperform everything .I was using Amsoil before I discovered Redline .I will sometimes use amsoil 2 stroke oil but that’s it after redline and it is easier to order.Amsoil does make good products especially gear oils but even more pricy and they do not disclose with base stocks and additives they use anymore while redline does and it is mostly Ester based for redline.

I have used this before in my 2010 Yaris and the Transmission performance greatly improved. I now plan to put it in my 2018 Sienna. Red Line makes great products so it is worth the money to me.
Update: I did a drain and fill at about 50,000 miles in the Sienna and it shifts very smooth now. No more “clunky” shifting out of the 8 speed. I plan on just doing a drain and fill of the transmission from here on out every 10,000 miles along with the oil changes since I pretty much have the vehicle positioned to do so at this time. I am very happy with this ATF.

my automatic clutch was having problems engaging causing stalls at many stops. my transmission was having trouble upshifting while accelerating; sometimes the clutch wouldn’t disengage causing a lot of revving without increased speed. i dealt with the problem for about 9 months when i finally ran across a project farm video about transmission fluid. he found that this stuff had the best additive package and it made me think that i needed to try this before i gave up on my old sonata. sure enough, the transmission is shifting like a dream and no more stalling at stops. 3.5 quarts of expensive transmission fluid to avoid paying for a 5000$ transmission is value up the wazoo.

I have an 08 TL and initially in online forums everyone said to switch to D4 when I used D4 on the TL it made the gears basically slam into gear. That was a 50/50 mix of DW1 and D4. Now I saw D6 is the more appropriate replacement for DW1 and I have 50/50 of DW1 and D6 and holy crap does the car feel amazing. I love the feel of the shifts now, they are super buttery but also firm. I definitely recommend at least a mix of D6 and Honda DW1, if not try the full drain and fill with just D6.

I used this in an older car, 1987 Oldsmobile Cutlass 442, and it works perfectly well. I used it in conjunction with a bottle of Lucas Transmission fluid conditioner.

I have not found any products from any other manufacture for ATF, Gear Lube, MTF, and Power Steering Fluid that performs better!
I have tested Red Line products in cars and trucks made by Toyota, General Motors, Chrysler in daily drivers , professional racing cars, daily drivers that where tracked and off road vechiles.
I have tested their products with readily available UOA both in house and third parties. I have done anylytical tear downs. I have had access to OEM manufacture data and testing. If I have to use an off the shelf product and I want the best Red Line is the way to go.
In their ATF line up I have used D4, D6, and C+ ATF. I am currently using D6 in a Toyota.
They have changed ownership not long ago but no reason to suspect their products have changed any in that time.

D6の低燃費って事で購入
外車向けアイシン（スイフトスポーツの採用している）純正低燃費オイルと同じ位の質感
燃費も少し上がった
悪くないけど滑り始めた9万キロ以上のアイシンには柔らかすぎて異音が収まらなかった
滑り始めた車両にはD4の方が良さそう…山登りをしても劣化が少ない気がする
低燃費ATFと普通のATFの違いはかなりあると思う…山とかは普通のATFのが音は好きかな
海外向けアイシンとかは低燃費系のATFを適合検索すると進められるけどD6もD4も好みで選んでいいと思う
距離もどれくらい乗ったかとかも重要…他のユーザーは アイシン製 ATFワイドレンジ AFW+を
使用している人が多いが…それが実は正解なのかもとかなり感じている…前回使用したスノコ国産ATFに
戻す予定です（普通のシンセティックは峠とかを行くと一気に劣化してまさかの1ヶ月でトルク感と異音が戻った…峠いくならエステルベースにすべし）
ATFは物によって継ぎ足ししたら古いオイルがしんでえらい事になるので注意（リキモリを入れたら純正ATFが終わったできるだけ入れ替えるべき）…逆にエステルとかは
そういった悪さが少ない気はしました。
