How the product is refined surpasses any transmission fluid sold out there today. Excellent product that will protect your transmission.

The best transmission fluid I have ever used. Can totally tell the difference in how my 97 f350 7.3 drives and shifts. And I have the peace of mind of using amsoil in my truck.

I replaced the OEM GM fluid with the Signature Series fluid and no more shudder, my transmission shifts smoother and runs cooler!!

I have used Amsoil products in several of my vehicles and have NEVER had an issue with performance after installing. Two vehicles had noted over-due transmission fluid changes; one over due by 96k and the other over due by 164k ( Yes, that's right ). After removing the pan, thorough cleaning, filter replacement and at least one additional drain = NO! transmission issues due to the fluid change. Don't let mechanics convince you to never change your fluid, if the transmission is operating normally and you are careful and keep the pan and filter dust and lint free, I am convinced you will have no issues after the fluid change. I have full confidence in Amsoil products. Install the best and expect the best protection, reliability and fuel mileage.

My transmission started slipping between shifts and was getting worse. The transmission shop said I needed to rebuild the transmission. I did a complete exchange with AMSOIL ATF and I haven't had a problem since. That was 90,000 miles ago!

Works for my VW, Ford diesel truck and my Isuzu Trooper. Can’t beat the Preformance and the convenience of just needing one type of fluid for all my vehicles.

Very fast delivery. Most convenient container that I have ever used... never wasted or spilled a drop.

Easy to use and put in. I seem to gain some fuel mileage. I did this on my 2002&2003 Tahoe. I did change all fluids with Amsoil products.

It’s great AMSOIL pays attention and correctly tells you to use this for your transfer case in a 2002 Ford Explorer rather than gear oil or the same transmission fluid that you use for a pan drop because it is a different fluid. As always great quality.

I would never have believed how good it was until I used it.

I got this for my 98 Honda Accord it had a hard shift of each gear. Sometime when turning I would loose power and it would just start revving up before it would go back into gear. With in 1 day of using AMS transmission fluid the was so much better shifting not even hard and no problem around turns now. Will do another drain in 1 month and put fresh fluid again.

I have heard a whole lot of good about the Amsoil products. my wife has got a Jeep Renegade and it was time to change the transmission fluid so i tried Amsoil Synthetic Transmission fluid And as what i heard it works as advertised, I have noticed more of a snap when shifting into gears, then before. Very good product

Definitely worth protecting your transmission with the best.

I've put this in my 2017 Chevrolet Silverado in place of the Dexron VI from GM and I must say it's a vast improvement! The shifts are smoother and the transmission temps are lower. I highly recommend this to anyone with the newer GM 6 and 8 speed transmissions, you'll be happy with the results!

Not much to say, I only use the best materials, fluids available on my machines, so I am pretty much Amsoil dependent. Which can only be a good thing.

easy to use containers

So far I’ve used Amsoil’s gear oil and transmission fluid and I can tell you I feel the difference! I’d highly recommend their products and great customer service. 👍🏽

Smoother shifting, smoother running in all RPM’s, I’m very impressed with my transmission working absolutely perfect on AMSOIL signature series full synthetic fuel efficient transmission fluid.

Have been using this product close to 40 years.

Highly recommended to use this brand in transmission. Last longer and better lubricant..
