After filter and oil change the transmission shifts smooth again. Shuttered before which it doesnt do anymore. Would buy again

I have a 2016 EcoDiesel, Amsoil Products are my go to for protecting and performance. I Tow a 7,000lb trailer and want the additional hi-temp protection when towing. I also use 5w-40 6x diesel oil for the same reasons!!

Orders always come in fast. After switching to amsoils transmission fluid my truck shifts noticeably smoother. Great product

I tow a lot over the Rocky Mountains and I need the best transmission fluid out there Since I switch to amsoil I have had no issues with temp. Amsoil fluid is by far the best out there for any job

Amsoil is awesome, I use it in all my vehicles.

Did a drain and fill on my 2011 Hyundai Elantra, only got about 40% of the fluid changed but the difference is there. Shifts are definitely smoother, impressed. I will do another drain and fill in the spring to get even more of the old maxxlife out of there.

I’ve been using this for years in my 08 F150 transfer case and it works great.

I have used this transmission fluid on my 2013 Lexus GS350 from the first fluid change at 40,000 miles. I now have 217,000 miles and the transmission is PERFECT. It is MUCH BETTER than Toyota's WS fluid in my opinion. It is more robust, the inside of the transmission looks like NEW. AMSOIL FOREVER!!!!

vraiment intéressant1; le contenu est de qualité supérieur et que dire du contenant, vraiment utile. Pas besoin d'utiliser une pompe manuel!

Purchased to refill the Transfer case on our ‘22 Durango AWD. Easy to use. Seems to help make our SUV run smoother. Very pleased.

I Trust Amsoil with my new to me F150 for all new fluids throughout.

Put the stuff in my 01 3500 Silverado with an 8.1 Allison transmission transmission has never shipped it better I regularly keep up on my services and this time I went with AMSOIL. Nothing beats it.

Great product

This was my first time using any amsoil products and I got the ULV transmission fluid. It has a noticeable difference on shifting feel, it made my van drive better and downshift smoother. I will be using amsoil for all my lubricants and considering I have a mechanic business I will be ordering a decent amount fluids. I recommend everyone use Amsoil products!

Great replacement for Nissan Matic J. At near 297,000 miles, the transmission is shifting like butter. Very happy with the outcome of using this oil for the long run.

Dealership wanted $200 for fluids for my transfer case. Amsoil cost me $75, shipped to my house, and it comes in the convenient squeeze pouches. Literally saves you time and money, can't recommend enough.

Laggy shifts and hard shifts completly gone back to smooth as can be shifts. Brought it to ford three times and they couldn’t figure it out

Squeeze bottle is nice

Awesome product! Awesome service!

If you're running a ZF 9-speed transmission, AMSOIL Signature Series ATF (blue cap) is a fantastic upgrade. If you're hesitant to move away from OEM fluid, it's perfectly fine to stick with it. But if you're on the fence — especially if you're tired of rough or inconsistent shifting — this fluid is worth the switch. Not only did it make my vehicle run smoother and shift more confidently, but I trust it to provide long-term protection thanks to its superior formulation.
