Beck/Arnley’s new premium OE automatic transmission fluid for type T-IV vehicles is a superior quality formulation of high-performance base oils and carefully selected additives, including a unique mix of friction materials for the specific pressure settings present in Toyota, Lexus and Scion automatic transmissions, to help promote smooth shifting in extreme temperatures and prevent transmission shudder. This formula is chemically balanced to help protect seals and “O” rings, and to provide corrosion, rust and wear protection, as well as resistance to oxidation to prolong fluid life.
