Customer Ratings & Reviews

I demanded satisfaction and Amsoil came though. This stuff is as dynominal as black bear diners thick cut bacon. It's as if it were delivered straight from the gods on a golden chariot. The shifts are so silky smooth it puts kellygold butter to shame. To sum it all up in one word SHIFTTASTIC! Signed Dab O Doubloons

It is very important to have a good transmission in the car. My Honda Odyssey 2016 has 250000 km runs and probably will need transmission repair soon. I want to prolongate life time of the transmission and that's why I'm going to use best quality transmission fluid. It is a bit expensive but savings of repairs are more important. I hope it will lasting long-term.

I have used Amsoil products for many years. The reason is simple. The product is the best you can buy in my opinion.

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.

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!

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!

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.

I do some heavy towing with my 2500HD duramax with an Allison. So far so good. Expect great things from the best.

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.

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!

Super easy bag, makes filling a breeze!

The container made the fluid change really clean and easy.

The item came to my doorstep within a week was packaged well and then it was easy to use on my Ram 3500

When I changed this out on a used caravan, I noticed a drop in temp of around 4-5 degrees.

Best quality

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!
