Customer Ratings & Reviews

Great product, been using it for years. I definitely like the extended change intervals.

I tried to purchase the manufacturer-approved transmission fluid for my wife's 2024 Telluride, but none of the dealerships or warehouse outlets carried the Kia-supported fluid. This AMSOIL product covers the specific type required. At 4 quarts, it is an exact replenishment of the fluid volume that is drained. One drain, clean the drain plug magnet, replenish. Drive for a short period of time, drain, clean the drain plug magnet, replace the filter, replenish. It's that simple.

Chevy Silverado started to get the Transmission Shudder, Complete trans Service stopped it.

This fluid is too expensive. A company this big can't figure out how to properly ship their product? Three of the five bottles were open and leaking. Shop rags included were soaked in transmission fluid. After over a week, I received my order a day after receiving an email saying the package was undeliverable. Not likely to do more business with Amsoil. Not worth the extra expense or trouble!

My 10 speed transmission has never shifted better. I started to have issues with rough shifting with or without towing. Since I put in AMSOIL fluid I haven’t had an issue and the hard shifting has ceased

Used synthetic trans fluid to do a recommended power steering fluid flush and change on Gen5 4Runner - worked great and rack is again smooth as silk.

Flushed out my old toyota ws fluid and used amsoil atf in my 23 4runner. So far I'm really liking it. Shifts good.

Using this in 87 corvette 700r4 transmission. Made shifting very smooth and on last change left zero particles after 50 K miles.

You can never go wrong with Amsoil…

After doing a transmission fluid and filter change on my 2019 Silverado, transmission shudder stopped

I had about 116k on the 2021 10R140 F-350 transmission. Of that 116k, about 10-12k was heavy (26k trailer) pulling, maybe 20k moderate trailer pull, and the rest highway/in town driving. I started to notice some “shuddering” between gear shifts, and began dreading what I was about to witness when I dropped the pan, per stories from some friends and family. But, the pan drop and filter change was a pleasant surprise, as I did not see any metal particles, shavings, etc.. So I changed the filter, topped it off (about 8-9 qts) of Amsoil ULV ATF, and went back to driving. It shifts like a hydrostatic transmission now - smooth as silk. It is a world of difference. Pulled another 24k pound load a few days later, and same result - smooth. Before the fluid change, the transmission was hesitant on cold mornings, almost reluctant to do much of anything; I had to warm it up for a few minutes before it would engage. Now? Put it in gear and go. It performs like it did when I bought it. I’ve used Amsoil products for over 25 years, and they cannot be beat. These trucks cost too much and have too much potential for quirky problems to be running anything other than Amsoil, a superior product line that has consistently delivered more protection for decades than the big box store retail shelf or OEM brands could ever dream of offering.

I did my first transfer case fluid change this more. I cannot give a review yet, but I’m sure it’s better than the Mopar brand. I love all the Amsoil products I’ve used and will continue to use.

Replaced my trans filter and used the specified oil for my 2010 f150 at 120000 miles. I also installed an extra capacity pan requiring 9.5 quarts this made it convenient. The oil itself really made a difference you felt the difference in shifting way smoother

It’s the Best I can find

My car shifts smooth as soon as I got my transmission flushed on my car. Takes off very smoothly as well.

best oil in the market

Is the best oil I have bought it works great in my truck thank you

delivery was quick, product showed up as expected, filled my transmission in my F350 diesel

This product is rock solid on performance. Works well and last a long time even in hot Texas driving for long distances often.

Great gear oil and easy to use
