Customer Ratings & Reviews

I use this faithfully in my boats transmission. Stays looking new even after its life expectancy. Shifts are smooth and effortless.

The best transmission fluid that I ever purchased. My transmission was slipping when shifting into upper gears. I drain the old transmission fluid. I open the new transmission the smell itself was so rich. I knew then that this transmission fluid a very good brand. Now my transmission works like new, no slipping whatsoever. My vehicle feels new "yaaaaaaaa'

I was using redline mt90 before switching to amsoil and it gave me a smoother shifting experience. There used to be a metal like sound when switching from 1st to 2nd and it went away instantly.

I like the idea of long interval changes.

New package makes this super simple to install when you’re underneath the vehicle. Well done!

Great Product. It is the only Transmission Fluid that I use

The transfer case in my 89 GMC was a little low due to bad output shaft seal, but not enough to explain the quieter operation after replacing the seal and switching to this synthetic ATF.

So far I can say the shift of my transmission is sooner as if the car was new again, also much more smooth.

This is a new use for me. Just changed it about a month ago in my G56. I added an extra quart and it is shifting smoother. I do notice that I can hear the actual gears as I shift through them more now. I am happy with the performance so far. Time will tell if it is better on the metal shavings side. When I drained the last oil there was considerable shavings on the magnet.

Great product. Has been in all my trucks since 2008. Even at recommended interval and hard towing the fluid was nice and red

Upon installing this transmission fluid. I immediately noticed lowered operating temps and smoother operation of my Jeeps trans.

The "filled for life" ZF 6-speed transmission in my 2011 Land Rover LR4 with 150,000 miles was starting to shutter on hard acceleration and RPM would drift +/-50 on the highway. A filter and fluid change with AMSOIL Fuel-Eff ATF completely cleared the shutter and I don't notice any RPM drift. The plastic bag container was very convenient to fill the ZF transmission with a side fill hole on the transmission.

The replacement of "stock" transmission fluid to this has given me a seat of the pants, better overall shifting transmission and has eliminated the "stuttering" when shifting into overdrive. Highly recommend, as it really is better than the factory filled transmission in real world driving/performance.

I used this product in my Nissan Sentra 1.6 automatic transmission and after changing the filter and replacing the fluid, it made the vehicle run smooth, i can wait to see how much smoother my car will feel once i change the mounts.

Replaced my transfer case fluid with AMSOIL ATF and noticed smoother quieter ride right away!
