Try using Amsoil coolant, with the Dominator Coolant Boost.

Most Toyota CVT transmissions use standard ATF, NOT the CVT fluid. Be very careful to use exactly what Toyota specifies.

@Jimi i want to try amsoil synthetic . How is it running in your vehicle. Is it any good

@Jimi How long have you been running the Amsoil fluid and which one ?

Make sure Mr Watson is your dealer.

Armando, Amsoil does not make fluid for the manual trans for the Sonic.

Yes, Amsoil ATL Fuel Efficient transmission fluid is Dexron VI rated.

Thank u dan I been searching this answer on the internet for 5 hrs .my 4l60e use devron vi/6 . So is ok for this blue sticker amsoil ATL transmission

@@jimmycontreras4087 My personal vehicle is a 2006 Chevrolet Silverado 1500 with a 4L60, it started slipping around 135k miles last year. I had just became a dealer. I told my wife, ‘instead of us buying a new trans or rebuild this one, lets try Amsoil LV ATF’ I swapped it out, flushed the torque converter, new filter. It now has 155k miles. Hasnt missed a beat. Amsoil ATF hasnt fixed anything but it has a revitalization characteristic. I am sure soon it will slip again, because of the poor maintenance by the previous owner. Ill rebuild it and when I do, ill make sure the builder uses Amsoil LV ATF! :)

Robert, Amsoil ATL (Fuel Efficient ATF) is the correct fluid. Let me know the vehicle you are using the fluid in and I can double check the application. If you are looking to buy Amsoil, I would be delighted to show you how to get the best price and buy for less. My email danwatson@thelubepage.com

Jack, Amsoil ATL Sig Series Fuel Efficient Trans Fluid is WS rated. WS is the Toyota spec for the 2023 8 speed. Email me danwatson@theLubepage.com for information on the Preferred Customer (PC) program for discount pricing.

Emailed you but never got a reply

Jack, you said you emailed me but I didn't see the email. Use my gmail address danwatson2948@gmail.com or dwatson2@cfl.rr.com Sorry Dan!

when in doubt 30,000 us miles / 50,000km is always a safe point to change fluid early if you are using a regular product that isnt synthetic. Most people won't do it that soon tho.

Use Amsoil CVT if you have a CVT trans.

John, NO! Matic P is an Ultra Low Viscosity and some additional specific requirements that prevents one of the Amsoil ATF's meeting the spec.

@@thelubepage Thank you for responding. I hope Amsoil will have Matic P in near future. Or MB 236.17

I think no manufacturer wants their powertrain to last a really long time easily! :D

So ?

Boomer Guy, I'm also a Certified Lubrication Specialist, STLE so I stand by my statements as a Specialist certified by an independent organization (STLE). I can send you a copy of the official Tech-sheet produced by Amsoil that list Toyota T-IV as covered by the Amsoil ATF, just need your email.

@@thelubepage I'm sorry to be so late getting back to you. Since my previous post, I have been using AMSOIL OE ATF in my VW Mk 5 Rabbit, my 2009 Honda Fit and my 2003 Honda Accord. All the vehicles have shown shifting improvement. I also use AMSOIL CVT fluid in my wife's 2016 Honda HR-V with shifting improvement. Thanks again for your info and your response.
