    Good product; awkward packaging
    By  DAVID R,  a  Verified Buyer  from  Colorado  on  February 21, 2021
    Package would be good for adding to differentials, but try pouring into a long funnel for transmission, while holding the funnel with one hand and attempting to pour a flimsy bag of oil with the other hand. For this purpose, I would rather use a solid quart container.
    Bottom Line
    Yes, I would recommend this to a friend.

    Transmission oil for Toyota tacoma
    By  Harley Rider 808,  a  Verified Buyer  from  Hawaii  on  February 21, 2021
    Amsoil you guys are awesome! I flushed the transmission in my 2011 tacoma and added your oil and I can honestly say it shifts WAY BETTER THAN WHEN IT WAS NEW! It's shifts smoother and quicker which definitely helps automatic transmission clutches last a lot longer! The truck feels like it actually has more power. Keep up the AWESOME WORK GUYS!
    Bottom Line
    Yes, I would recommend this to a friend.

    Smooth
    By  JOEL,  a  Verified Buyer  on  February 21, 2021
    Used in 2015 gmc sierra 6.2l 8 speed. 45k . Had been serviced under warranty at 30k due to torque converter judder, judder came back at 45k ( only 15k since service) . Changed fluid with amsoil this time. Judder is gone again, but furthermore, shifts feel more positive now. Took only a few miles of city driving for adaptive shifting to adjust for the different and non worn fluid. Truck has never driven this smooth!
    Bottom Line
    Yes, I would recommend this to a friend.

    ATF goodness
    By  TODD,  a  Verified Buyer  from  nevada  on  February 20, 2021
    I used this oil at 30,000 mile service on a 2014 Chevy Cruze 1.4 turbo . Seeing as these do not have a serviceable filter for the transmission, I installed a remote unit. I change the fluid and filter every 30,000 miles. I now have over 211,000 miles and have no problems with it. I use AMSOIL for all the fluids on this vehicle as it is my primary commuter for work. This is by far the best oil I have ever used.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great ATF
    By  LEROY,  a  Verified Buyer  from  Florida  on  February 20, 2021
    I do some heavy towing with my 2500HD duramax with an Allison. So far so good. Expect great things from the best.

    So-Atf
    By  CHRISTIAN,  a  Verified Buyer  from  Dana point  on  February 14, 2021
    I purchased this transmission fluid for my ram 2500 daily tow vehicle, and at 67000 miles without a transmission service of severs duty, I changed the fluid and filter as per manual. Not thinking there would be any changes to notice, I was pleasantly surprised when I noticed more crisp gear shifts and less lag in transition. I also noticed that my transmission temperature is roughly 3 degrees cooler. (Just my observation) I highly recommend this product for severe duty vehicles.
    Bottom Line
    Yes, I would recommend this to a friend.

    Exactly what I wanted
    By  LAYTON,  a  Verified Buyer  from  Beeville Texas   on  February 13, 2021
    Put this in my 68RFE and it’s a game changer, I now run cooler and tow more.. other companies will say oil is oil but that’s not 100% true. Give it a try! You will be happy you did!
    Bottom Line
    Yes, I would recommend this to a friend.

    Happy Tundra
    By  ERIK,  a  Verified Buyer  from  Binghamton NY  on  January 30, 2021
    I followed Don Smith’s YouTube video on how to properly flush a second gen. Tundra transmission using Amsoil. Time well spent. Excellent, even smoother shifting , all the time, with a drop in operating temperature. I now rest easy knowing that my transmission is protected by the very best!
    Bottom Line
    Yes, I would recommend this to a friend.

    By  DANIEL,  a  Verified Buyer  on  January 28, 2021
    Just started using more Amsoil products to service my 2014 Silverado after 91000+ miles. It was due by the looks of fluid that came out of it. Must say the Amsoil products look good and are very slick. Time will tell how well they perform over the long haul.

    Yes, I would recommend this to a friend.
