I called Redline Oil and Amsoil Tech Support Dept.'s and they told me that they have nothing compatible with Toyota Type T-IV Trans. Oil.....to the contrary....the dealers for both Mfg. quoted me different......just wanted to save someone a huge and a coastly mistake in case you plan on replacing your ATF....just make sure it is Toyota Type T-IV.
Also see the following thread on the 80-series:
