Customer Ratings & Reviews

I did a full fluid replacement on my 2023 Cadillac XT6 9 speed transmission at 43000 miles. Transmission was starting to shudder with the factory fluid. This fluid fixed the shudder issue instantly by 95%. It worked so good I changed my Silverado 6L80 fluid over as preventative maintenance.

Dont waste your money didnt notice anything different in shifting or how my car drives, everybody claims AMSOil is the best and you will notice the difference in shifting, well there is no difference dont waste your money

On two of my cars, in cold weather, in temperatures as low as 40 below C, the tranny would chatter until it warmed up. I replaced the oil with this 100% tranny oil, and in both cars, I no longer hear chatter noise from the tranny. That is saying a lot to me. Also this oil last longer between tranny oil changes. Highly recommend this oil if you want the tranny to last longer.

We changed our ATF over to the amsoil full synthetic at 80,000 miles. I can't say the truck shifted hard before, but I will say it shifts noticeably smoother, and quicker now. We pull a trailer with a couple of bikes in it so I will be watching to see the difference then.

Very satisfied. Thanks

Just did a 3x3 fluid change on my Acura tl and used this fluid and finished off with the signature series and this bad boy is ready for another 30k miles I can’t recommend this fluid enough for your services

This trammision fluid drain and fill is supposed to be done every 30,000 miles according to the manual. Until 100,000 I had used the dealership, the transmission was never discussed with me and my lack of knowledge or ignorance led me to believe everything was ok. When starting the the Hyundai and just starting to get to about 10mph the transmission always felt like it slipped, only on cold starts where the vehicle has sat all day/overnight. I added the Amsoil transmission fluid and now no more slip. Super smooth shifts, I stand behind Amsoil and their line of products.

I drive a 2015 Ram 1500 ST 3.6 V6 with a 8 speed 845RE transmission. And this was my first time using a different brand other than the recommended mopar fluid. And Amsoil came thru again! Shifting is way smoother, transmission handles the steep grades I drive daily high revving for 10 miles of steep grade climbs and my transmission temp stays cool and runs like a champion. No matter if I'm hauling a** in low gears or cruising the highway at +75 mph. My transmission is healthier than ever. I'm ditching the mopar for good. Amsoil gots me as a loyal customer indefinitely

this got rid of the jump and hard shift in my wifes 2016 chevy traverse. we like it.

I just started using amsoil in the last couple of months and it is unbelievable . I’ve used the liquid gold for my engine, transmission, differentials, and transfer case. I’ve also used the oil, flush treatment and the gas treatment to clean the fuel injectors. All the different products that I’ve used have worked great so far I am also very happy with the company and how they give you discounts for a nominal membership fee. I recommend Amsoil to everybody.

The oe fuel efficient transmission fluid has totally transformed all my transmissions and others that I have serviced. not only are they smoother but the temps dropped on all and has helped on fuel efficiency by a significant amount. Amsoil products actually do exactly what they say it will do. I'm an Amsoil enthusiasts now!!!

Use exclusively in my Aisin 6speed tranny

Put this in my 2015 silverado 1500 after having some high trans temps and since I have switched to Amsoil it runs 10-15 degrees cooler than it would have before and I have never had the temperature come up like it did the the original fluid.

Brought the mpg's back up in my wifes traverse and got rid of a hard kick on acceleration. I love it in my 17 chevy duramax 6 speed allison. it gets changed again next week. I have run this in it since its first fluid change and now have 150k on it and it shifts nice and mpg's are not too bad for a huge diesel truck.

Works perfectly in the 8-speed Genesis automatic transmission. Smoother delivery of power on a 110k mile engine. Will buy again for all transmission jobs on my vehicles!

One of the best!

Smooth Performance and durability in my high mileage vehicle

After 30k miles, Ive drained and filled with OE-Efficient ATF 3 times. Ever since then, I drain and refill once every 15k miles sknce I drive 30k miles annually and do it every end of May(before summer starts) and beginning of November(after summer has passed). I currently have 180k miles. Every drain and fill, fresh fluid always comes out and I barely have any metal pieces on my magnetic drain plug. At this rate, my transmission will last forever. My car never slipped. Changing gears is extremely smooth like butter. I will never use any manufacturer ATF ever.

good oil

Love amilsoil products been running them in all my vehicles for 5+ years!
