Experienced Toyota / Lexus Aisin 8-Speed (AB60F / A960 / Aisin 8F57) specialists since 1987. Free computer diagnostic, lifetime warranty on rebuilds.
Toyota's latest 8-speed automatic family (including the Aisin 8F57) is found in current-generation Highlanders, Siennas, and Lexus crossovers. It's a newer unit with a strong track record so far.
