I am running Redline D6 in every car I own, one is my wife's 2014 Rav4 which we use to tow a small 14 ft boat with decks and 25 hp motor. In fact I run a Qt of Redline racing and light weight racing ATF that is a Type-F with no slip agents. I use both to match the viscosity of D6. I also have added a external trans cooler too. I have zero issues. WS is a horrible price point cheap semi-synthetic.
While everyone likes Maxlife and I have use it in my daughters Honda, Maxlife is just a group 3 fluid. I want a group 4 (Amsoil) or in the case of Redline D6 a group 4/5. I did a complete 95% change of the WS by pulling the pan and refilling and getting a long hose and attach it to the "hockey puck" cooler/heater that does almost nothing to cool since there is so so little ares in it. while kneeling by the ignition key I start up and let it suck the fresh oil in the pan and when you hear it to start sucking air I shut it down and refill the trans. I think it took 4-5 of this way till I saw clean D6. This clean out all the [censored] WS out of the torque convertor. I will only use top tier group 4 or group 5 in any of my ATF pumper. it is only $30 more then Maxlife, why bother with group 3 for that money. You get a lot better oil for $30 more.
