Customer Ratings & Reviews

Just changed fluid & filter on my 480LE 2005 Silverado 2500 4WD. Got 118,000 on it, babied by me for the last 21 years. AMSOIL Seems quiet and more smooth first miles. Its had a very loud first gear since new. First gear is straight cut instead if Swirl cut , I am told. Transmission never been apart, other than a billet torque converter about 10 years ago. Original converter was slipping Code P0894. Seems very quiet with the AMSOIL. I will continue to buy from you based on my current experience. Thank you :)

Great product, consistent, high quality, works exactly as claimed. It’s all I’ll use for my lubricant needs, from oil, to grease, to fuel treatment and more.

I saw an oil analysis of various transmission fluids online. Compared to the factory OEM transmission fluid, this provides much more protection.

Excellent product at a competitive price providing very good value. This can be said for the entire Amsoil product line. Only wish there were retailers in my area!

Lasts for longer than usual products.

Hard shift before the transmission is warm has stopped

Ram 2500 diesel truck transmission temps are lower and shifting is barely noticeable. Time will tell how my transmission fares.

Bought because oil reputation on oil will see seems to be great transmission seems to shift easier and smoother

So far so good 4x4 operation has been smooth and reliable. My transfer case is working better than ever. Would recommended

After using the other products from Amsoil I wouldn't think of putting anything else in my truck.

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…
