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

WS non synthetic. Lucious Garage says it's only 30 grand. REDLINE D6 is two classes better. This is a Group 4/5 true synthetic based fluid. Beware of $20-25 per gallon ATF from big-name oil companies. It's Group 3, meaning it's made from natural gas or dyno oil with no synthetic base. You get what you pay for. Use Redline or AMSOIL ATF. Your Prius will shift smoother, make less noise when regenerating and last longer. Too many Prius trances die due to a lack of fluid replacement. And the easiest way is to change the ATF transmission. Without bowl and filter. Drain and filler plug only.
