Driving a GMC I am always aware that the transmission is an issue. But my mind is put to ease using Amsoil. My transmission run 10 degrees cooler than it used too even pulling a trailer since I switched to Amsoil.

Great stuff, easy to use keeps engine running smoothly

I have a 21 Ford truck with the problematic 10 speed transmission. Bought the truck used and now has 160,000 miles on it. Changed out the trans fluid with my preferred AMSOIL ATF, and the transmission is running great. AMSOIL fluids are far superior in my book to anything else on the market. I plan on getting at least 500,000 miles out of this truck, so I will continue to use AMSOIL fluids, which I totally believe will help in making that happen.

my 2019 silverado 5.3 w/ 8spd trans 50k miles had a 1-2 shift that would dropout when cold since new- changed trans filter and used amsoils s/s atf , 2 weeks later did another drain and fill, the 1-2 harsh shift went away. i got 62k miles on it now. I will be doing a yearly drain and fill with amsoil ss atf . I use amsoil products in everything I own that uses oil/atf /fuel- and care care products

I use this product in the transfer case of my Jeep Rubicon and it has work well. The collapsible bottle makes it easy to fill the transfer case without a pump.

Ive got a 2011 GMC Sierra 1500 6 speed that i bought new and i change the ATF with Amsoil signature every 75,000 miles. Shes got 365,000 on her now same transmission no issues. Bought it in my 20's so its done a few burnouts and plenty of towing. Stuff must work

I travel 50,000 miles a year- I always use this in my vehicles- can’t assured a breakdown 1000 miles from home. I get better gas mileage, transmission stays cooler, smoother shifting, great product 10 out of 10!!

Amsoil ATF actually restored my car’s fuel efficiency. I don’t even know how that is possible. I notice my car’s highway mpg went from 27 mpg to 30 mpg. It is weird, I just don’t know how it is possible but it did happened. I thought changing motor oil, spark plugs and air filter would restore fuel efficiency, but it did. I am a loss for physics.

For this time around for the PM on my 19 year old truck, I decided to try AMSOIL. The shifting on the transfer case feels so smooth and effortless and highly recommend it.

My 10 speed never shifted this smooth before this. I did two drop and refill transmission refills. I'll do another 3rd one after 500 miles. This will give me at least 80% replacement. I have 110,000 miles.

I had a skip in the transmission in my 2022 Explorer King Ranch with 60k miles. I changed trans, both differentials, and transfer case fluids with amsoil products and it runs better than when I bought it and the trans issues are completely gone!

Excellent delivery time, performing great smoother shifting lower temps.

So far so good.

Specs are impeccable. I've tried several different ATFs for my power steering to combat some whine and groaning, Amsoil is clearly the best, better in my application than OE, Valvoline and Redline. Steering feels the best it has in years. Not cheap, and I wish it was easier to get hold of, but I still want some more of it.

Works well. Shifts smoothly.

Been running in a 6 speed automatic on a Dodge Grand Caravan. Changed to Amsoil at 70k miles. Changed again at 145k miles. Transmission fluid looked brand new. Same dark red color as the new fluid being put in. Transmission shifts smooth. Still working great.

All Amsoil products are great. Changed all my fluids in my 2025 RHO and it runs smooth and quite. I highly recommend these products .

Great oil no vehicle engine problems have over 400k on motor

I just did my first service on my Ford Raptor. I have a 10R80 transmission and the AMSOIL completely cured the trippy shifts. I’m looking forward to changing the fluid in my Honda. Although I didn’t receive my free tire gauge.
