Customer Ratings & Reviews

IMHO this is the best ATF one can use in their automatic transmission.

I use nothing but Amsoil lubricants in my 2016 GMC 2500hd . I put my trust in them to keep her in tip top shape .

Performed a 50,000 mile maintenance on my 19 Jeep Wrangler JL so decided to replace all fluids/oils with Amzoil Signature Series products. Used this in my ZF8 speed auto tranny. The shifts are smooth and enhanced the smooth performance of my ZF transmission. I go deep in the back country across the USA overlanding and need to insure reliability since the conditions are out of the norm with high elevations to high heat. Signature Series seems to work great.

It was time for the first fluid change in my 2019 Silverado 1500 with an eight speed transmission. Pan drop, filter change and then filled/cycled Amsoil Signature Series through oil cooler return line until it ran clean cherry red fluid. Topped off at proper transmission temperature and then drained the fluid from the transfer case and refilled it with Amsoil SS ATF fluid also. Afterwards I could feel the difference, especially in the lower gears as they seemed to shift with a little "bite" from one gear to the next. Truly pleased with the performance!

Je recommande vraiment cette huile, la meilleur que j'ai acheter! Je vois vraiment la différence entre les rapports comparément au autre huile. Et je connais plusieurs personne qui sont aussi satisfait que moi.

Very highly recommend the best you can get!!

Best transmission fluid money can buy

Excellent product. Could feel the difference with my truck after draining and filling the transmission fluid in my truck.

Transfer case fluid change was a breeze with the easy pour packaging. Satisfied customer.

Lexus rx350 2014 138k miles. My. Ar was over shifting/under shifting and shuddering at times in gears 2/3/4. I did a drain and fill with fill and the improvement was remarkable. I'll do another in a few hundred miles. Amsoil saved the day.

Great product recommend it worked out very good for me. I'm going to use it on all my other cars and trucks. 2020 Silverado Truck was shuttering pretty bad and when I flushed it out with a ams ATF oil it went away.

After switching to amsoil transmission shits and drives smoother

Removed transmission shutter completely recommend this for GM vehicles.

I use this fluid in Chevy Cruze diesels with the Aisin Automatic. It improves shift quality.

Transmission shifting so much better now no more jerks on light throttle inputs and that was just 1 gal of fluid swap will drive it for a while and drain and fill again with other gal. This is great stuff

I've always liked this products I used it since 2010

Testing Amsoil ATF in my 2002 F250. Over 375,000mi on truck. 200,000mi on Trans. 100,000mi on engine Truck runs great. Test are all good, then will use in my next new truck.

Testing Amsoil ATF in my Ford NP273F transfer case, and the Hydro boost with power steering system. I am ultra sensitive to changes in how my vehicles run. Rebuilt Transfer case as drive shaft runs on 3 internal bearings in the case. Runs smooth, great, cool temp. Also works great in Ford hydro boost & power steering system. Helped with smoothness & whine.

Tranny love it!

I just bought a 2018 gmc sierra with 112,000 miles. I wanted to exchange the trans fluid before I really started driving it. These trucks are known for bad transmissions. My other truck is a 2011 gmc sierra with 295,000 miles. I had done the trans fluid change a couple times and have used AMSOIL signature series 5w 30 since I bought it. It still runs and drives great. The bed is rusted away and the frame rotted out, otherwise I would still be driving it.
