2015 Highlander Lmtd
Great DIY video. Not to highjack your thread....I just had to reply to the above post.Toyota doesn't make transmission fluid (or any other fluid)...it's made for them by one of the tranny-fluid companies. I've never heard of any bad things about the WS (World Standard) fluid. Could you show me. I found ONE link and it was highly questionable.
The WS fluid Toyota sells is a very high quality - full synthetic fluid. It is expensive. The compatible fluids are just as expensive.
My 05 4runner had nothing but WS fluid. Sold truck with a little over 300k miles. No tranny issues. Wifes Lexus also - only WS fluid. Now has just under 200k miles and no transmission issues. This tranny place that changes my tranny fluid and almost all the local dealerships send their vehicles to for tranny work, only uses WS fluid for the Toyotas/Lexus vehicles. All others they use compatible fluids.
Probably won't have any problems using any other compatible fluid. But I really doubt Toyota's WS fluid is junk.
Toyota WS is not Synthetic ATF. The bottle nor the MSDS indicates the fluid is synthetic.
If you want a compatible synthetic fluid that meets or exceeds the WS specifications buy some Valvoline Max Life ATF. It is 100% synthetic and has been in all my vehicles for years. Not one vehicle has had a transmission issue. My 05 Honda Accord had 150,000 miles with MaxLife ATF from 20,000 miles. My 2015 Highlander also has been using it from 15000 miles. My 2011 Tundra uses Maxlife ATF as well....none of them having any transmission issues. It's worked so well for me my younger brother changed his 2016 Sequioa and Tundra transmission fluid from WS to Maxlife ATF.
