Howdy! I'm new to the forum but not new to car forums in general. Usually this is the place to go for good information and experience.I hope to get a Vibe for my wife in the next few years as a replacement for her Civic, but for now my in-laws have one.The drive in downtown Chicago and with 52,000 miles they have never changed their ATF. I can tell it needs it and I offered to do it for them. I finally found a filter for the MU4 tranny but now I find out that you have to buy the T-IV from the dealer. Is this true? Can I use something else? Is there something better like a Lucas or Red Line? I have never had a Toyota so this ATF spec was new to me.Any ideas? Thanks in advance.Paul

Yes, T-IV is only available from dealers. The only alternative to T-IV I know of is Mobil ATF 3309:

Do you think the Mobil is better or just a substitute? Anyone else have any ideas? I saw someone say something about AMsoil. Is this better? I don't have any experience with them.Paul

Don't know if the Mobil is better, just AFAIK it's the only other commercially available ATF that meets the T-IV spec. Can't go wrong with either the OEM stuff or Mobil. Others have used Amsoil, etc. without incident, but using something that doesn't meet the T-IV spec is a dice roll in the long run IMO.
