Review on 🚗 Red Line D6 AFT Auto Trans Fluid Gal (30705): Unleash Optimal Performance for Your Vehicle by Shane Popo

Have a 2009 Toyota with WS spec. Switched to Valvoline Maxlife atf for the first time; very nice upgrade from Toyota WS. This time I had 4 liters of Valvoline maxlife left and added 4 liters of Redline d6. Improved gear shift again. If you have a Toyota WS I strongly recommend replacing it with either maxlife or redline d6. There is no comparison. Toyota WS can't handle the heat. Flash point WS 175*. Maxlife flash point is 202* and Redline d6 flash point is 249*. Since heat is a big problem with automatic transmissions, I strongly recommend you switch to a fully synthetic oil like Valvoline Maxlife or Redline D6.
