Customer Ratings & Reviews

I bought this based on Amsoil's recommendation for a transmission rebuild but it meets Honda Z1 standard, not Honda DW-1. The Fuel Effecient ATF with blue cap is what you want if you have an older Honda.

Changed trans fluid in my 16 2.8 Duramax and have decided to use it in my Allison as well.

So far so good. I forgot to order 2 more quarts.

Changed my tranny oil, and before I did, never notice any problem, after changing it with AMSOIL, made a big difference in shifting.

Excellent oil

Bought a 89 Dodge D 1002wd truck, has 100,000mi on it and had been sitting for 10 yrs. Transmission had been serviced at some point within the 100,000mi. Decided to install the Deep pan kit and use the Amsoil product. after 250mi with new fluid , it is shifting smoother than ever.

I have always used ams oil transmission fluid in my 66 GTO.

I have used Amsoil products for several years. I am confident this trans fluid will meet the high standards.

That s product help my transmission big time it took the shudder it had

Product works great, noticed aN immediate difference with shifting when cold. 2014 Tundra, 200k miles service.

Amazing fluid for my car don’t have those hard shift anymore will definitely buy more

Good to use in a transmission smooth up shifts and down shifts

Mon camion

Used on my wife’s Sante which had a replacement engine under warranty. At 160kms the transmission shifts smoother than before the service and drives like new.

I did a full fluid replacement on my 2023 Cadillac XT6 9 speed transmission at 43000 miles. Transmission was starting to shudder with the factory fluid. This fluid fixed the shudder issue instantly by 95%. It worked so good I changed my Silverado 6L80 fluid over as preventative maintenance.

Dont waste your money didnt notice anything different in shifting or how my car drives, everybody claims AMSOil is the best and you will notice the difference in shifting, well there is no difference dont waste your money

On two of my cars, in cold weather, in temperatures as low as 40 below C, the tranny would chatter until it warmed up. I replaced the oil with this 100% tranny oil, and in both cars, I no longer hear chatter noise from the tranny. That is saying a lot to me. Also this oil last longer between tranny oil changes. Highly recommend this oil if you want the tranny to last longer.

We changed our ATF over to the amsoil full synthetic at 80,000 miles. I can't say the truck shifted hard before, but I will say it shifts noticeably smoother, and quicker now. We pull a trailer with a couple of bikes in it so I will be watching to see the difference then.

Very satisfied. Thanks

Just did a 3x3 fluid change on my Acura tl and used this fluid and finished off with the signature series and this bad boy is ready for another 30k miles I can’t recommend this fluid enough for your services
