very good replacement

The product is as advertised, very good. The service is fast and reliable. Easy to order and arrived when promised.

Replaced dark red fluid with this bright red new Amsoil. Seems to work fine! Temperatures good.

2014 ram, 6.2L. Had the trans rebuilt with heavy duty upgrades. Always had a tiny random clunk on D/R. After swapping the trans fluid to Amsoil - no clunk. Smoother more responsive shifts. Cooler temps. Once again Amsoil has the right stuff and you can feel it!

I am in the middle of building a Dodge Challenger and from my friend telling me that for the expected heavy load, this is the best fluid he has ever used! So due to the expected load and my friends recommendation this will be the only fluid I will use! Thank you all so much!

2017 chevy silverado 5.3. 6L80 Drained, pan dropped and new filter. Smooth shifting. I was not having any problems. 39,254 miles on truck

This is quality trans fluid and I have been using Amsoil fluids starting in the late 80's and have never ever lost an engine (max 425k) or transmission (except when I sunk them off road/oopsy) and even then I have no clue if they would have worked as I verified water and had them rebuilt The ATF fluid truly helps the trans smooth out. Why settle for hype when you know this is quality.

This fluid made my Chevy Traverse shift much smoother. Now, I cannot even detect when it shifts into higher gears.

Do your new Chevy or GMC 2500/3500 HD a favor and replace the Transfer Case fluid with this stuff! Just compare the additive package this fluid has compared to AC Delco fluid, it's a no brainer.

If you have a Chevy or GMC 2500/3500 HD with a 10L1000 Transmission, this is the fluid for you! Do a complete flush with this fluid and you will won't even notice your truck shift gears, it's that smooth!

Works great Transmission goes into high gear lock up much better Picked up 2.5 mpg

First time ever using an Amsoil product. I just did one drain and fill. So far my transmission is shifting smooth. I’m feeling a difference already in just one fill

Needed to change my ram 1500 transfer case fluid. Found out it needed special fluid and found Amsoil had the stuff I needed. Fast shipping, great price and they are known for excellent quality products!

This high quality transmission fluid is Toyota approved WS for use in CVT transmissions. I used it for a 2014 Lexus ES300H hybrid and previously in my old 2008 Toyota Prius every 30K miles and sold it with 200K miles and never had a transmission issue. I'm going to continue using it in my Hybrid Toyota CVT transmission.

Love the packing, makes it easy to squeeze in like a capri sun. My transfer case operation is silent and smooth.

20k kilometers ago I had my transmission rebuild. So I run all Amsoil in everything accept my transmission until now and right away I noticed smoother shifting and I feel at ease now knowing what fluid is in my transmission. I highly recommend Amsoil on or in everything gear or engine related. Thanks Amsoil!!!;

Good quality

Only transmission fluid I use in my 2013 GMC Duramax with the 6 speed Allison. Transmission shifts smooth and effortlessly especially during a recent trip in the mountains with a 11k lbs trailer. Only transmission fluids I use in my vehicles.

I did a single drain and fill on my zf9 transmission at 30,000 miles. Shifts smoother. I will do a drain and fill every 30,000 miles or so for life of vehicle. Easy maintenance for long term reliability.

40,000 miles 2019 Honda Ridgeline 6 speed. Transmission was surging under low load and light throttle, you could see the tach raise and fall a thousand RPM. After doing one drain and fill that has completely gone away. This stuff works!
