I posted a thread under Maintenance to get feedback on long term use/results of Valvoline Maxlife ATF. Please chime in if you used it. https://www.clublexus.com/forums/maintenance/1038321-lllong-term-valvoline-maxlife-atf-good-or-bad.html#post11895058

 

I use Valvoline Max Life transmission fluid in my 2015 RX350 AWD with about 190k miles and my transmission shifts perfectly smooth and quickly. I do not know if the Valvoline Max Life transmission is a better fluid that the OEM WS transmission fluid, but it does perform well as an affordable easy to find alternative to the OEM fluid.

just making the link a little easier to get to.

 

I've also used it for years and it works fine.

 

Maxlife & Wix trans filters a few times, does the job.........

 

you used it for 190k miles? or since

 

I purchased my 2015 RX350 used with 172k miles and swapped the transmission fluid soon after. The Valvoline Max Life transmission fluid has been used from about 172k miles to about 190k miles without any issues in the old transmission.

Note: My 2015 RX350 did have a recent transmission fluid service when I bought it(drain plug was clean) , however it was overfilled and it slipped(hesitated) at around 15mph until I drained the excess amount and added the proper amount of Valvoline Max Life transmission fluid. No slipping or weird shifting after the fluid change.
