Customer Ratings & Reviews

Instant improvement on shifting and operating temp.

Most automakers insist the customer use only their OEM fluids, which work fine at first. But over time that smooth shifting gets rougher, often after only a few thousand miles.. Not so with AMSOIL Shifting is smooth and positive, operating temps are lower, and fuel mileage increases. I would not use any other fluid!.

I did a trans flush on my 08 E350 4matic after 95k miles. The stuff that came out was black, burned and smelled like totally burned gear oil. After switching I feel a real difference in the way it shifts. Much smoother and it doesn't shift hard into 2nd when in stop n go traffic anymore. I love it. Worth every penny.

Been using your product for many years and I always brag to people how excellent your products are.

I put this in a toyota corolla, toyota says not to put anything but toyota products in the trans. I didn't have any problems before, and I still haven't had any problems, I really can't tell any difference, works great !

I have a 2004 Honda Odyssey. I have been using Signature Multi Vehicle since the 2nd year of ownership with excellent results. I bought it new in 2003. Unfortunately I bought the newer Signature Fuel Efficient (blue cap) version ind installed about 6 months ago. Immediately I noticed a shudder. I switched back to MV (red cap) and have restored flawless operation. 170,000 miles on a Honda auto transmission. I owe that to Amsoil.

The car has more than 235,000 miles, the shifting is a bit hard but I knew about it since is an old transmission, and it has been like that since I bought it in Feb of 2016, but is noticeable less than the fluid that it had before. I wanted to use Amsoil to protect it as long as I can own the car. Is an 2002 Subaru WRX Wagon, all original, engine, turbo, transmission, everything. And my goal is to go past 300,000 miles with everything original, all with the protection of Amsoil. The color of the fluid still looks cherry red, for the few months that I had put it in my car. Most of the driving has been city driving, stop and go traffic, and I cannot complain. Great product.

I use it in my automatic transmission in my Sierra 4-wheel drive and my transfer case and it will waste the temperature all the way around better lubricant

With this fluid in our Subaru Impreza Outback Sport transmission the automatic shift operation became very apparently smoother first time/ongoing operating .. Will be using in my F-150 5.0 soon ..

Now with 458,000 miles on the original auto trans, I can't imagine using anything but Amsoil ATF. Nuff, said!

I recently purchased 2 cases of Signature Series ATF for my 2006 Volvo V70R. My previous Volvo, a '98 S70 GLT, which I bought with 60,000 miles, was serviced with Amsoil ATF and made a big difference in its shifting quality besides the expected increase in protection. I have used it in all my automatics as well as some of my children's vehicles. I haven't done the flush on the V70R yet, but it is scheduled with my Volvo independent shop next week. It is a "sealed" transmission and has a specific process making it challenging for a do-it-your-self person.

My trucks manual transmission calls for automatic trans fluid So I installed Amsoil The shifting is now smooth and quiet.

I used this fluid in the transmission of my truck as well as the transfercase.

It has helped quite things down Greatly on cool start ups. Great product.

I use this oil in the transfer case every 50,000. It has a distinctive red color when put put into the unit, and then has mild discoloration when changed. The unit switches in and out of 4WD just as it was new, no hesitation and no worn out internal parts at 100,000 miles. I trust the quality of Amsoil transmission fluid along with all Amsoil products. I ordered the quart bottle pump for the fluid transfer and worked great, very little leak from pump, which means no wasted fluid on the floor of my garage. I am a lifetime customer!!!

Replaced auto trans fluid in my F150 2012 F150 4x4 Ecoboost. Only Amsoil in my vehicles.

Switched to this in a wranglers 42RLE at 108k, This was its first drivetrain service so I was expecting a little slippage but instead its shifting super smooth. Couldn't be happier!

I used this product in my race car with stock unknown milage trans and put down 450+ WHP for a good amount of races. It was this fluid that helped this trans stay together and last. Will continue to use with new rebuilt trans!

I use this transmission fluid in my daily driver diesel truck and will soon be using it in my 70 chevelle. Ive been using Amsoil engine oil since 2008 and its all I use in my vehicles. So this past summer Ive been switching my vehicles to Amsoil transmission fluid.

Put this in my Chrysler Crossfire, and im no expert but the transmission shop said, "Amsoil is good stuff and that i take care of my car." Mind you months later after my purchase, car is shifting butter smooth.
