I performed an entire Amsoil fluid swap on my truck of 150K miles. It took no time at all to see a 2.5 mpg increase in fuel savings. Will recover the cost of the fluid changes in a short amount of time.

Outstanding, changed transmission and transfer case fluid. Runs cooler, shifts smoother, win win in my book!

i'm a master technician and i use this to fix the infamous Chevy 8 speed judder! no need to do the triple flush....just 7 qts does the trick. best stuff out there!

Same as the oil. I really don’t know how to test the performance. I would be glad to send a sample.

Great product..fast shipping

I was truly impressed with the performance of this oil in my JK17. The shifting is now noticeably smoother, and I wholeheartedly recommend it to anyone seeking a top-notch ATF for their Jeeps. Thank you, Amsoil!

I love this product and I always recommend amsoil to family and friends.

MUCH better than what came from the factory

I recently purchased a very low mileage 2006 Toyota Corolla that had never had the transmission fluid changed(105k) . It was very noisy and rough shifting .I drained the old fluid and changed the filter and refilled it with Amsoils Signature Series Transmission fluid and wow! What a difference it made, transmission showing 20 degrees cooler( per the trans temp gauge) and is so much smoother and quieter.

This is a heads up on product packaging. If the customer doesn't inform the vendor of packaging problems , the vendor doesn't know what to fix. The foil seal under the cap sometime arrives leaking , with only the plastic cap to provide a seal. If the the cap isn't torqued down tight the fluid gets on the other products. Also some of the "bags" of fluid seep out of the seams on the bottom of the bag. I discovered this after having stocked them on wooden shelves , discovering the wet wood under the bag later. I'm not complaining, I'm making you aware that's all ! Amsoil is the Best !

Recently took possession of a 2019 GMC Sierra 1500 w/10-speed automatic transmission. Definitely noticed some transmission slipping and hard shifts from time to time. Have read all about the problems people have been having with this transmission. Changed the transmission fluid out for the Amsoil Signature Series ATF and immediately noticed a smoother, more consistent transmission performance. Would definitely recommend anyone with the GMC 10-speed transmission make this change!

Better than oem

Shipped fast and was correct amount for fluid and filter change. Shifts smooth and should last another 100 k miles. Love all ams oil products.

It gets plenty hot in the summer down in Louisiana. I use Amsoil transmission fluid to keep my trans cool and pulling.

Phase 2 done. Transmission, Transfer case, both Differentials. Cooling system left to do for 100%

Changed transmission, transfer case, and both differentials. Shifting is smoother, especially when towing my RV. Mechanics liked the easy handling of the "pouch packs".

did 3 drain and fills (3 of 7.6 QT) and calculate about 80% of old fluid exchanged. I noticed quieter smoothing shifting after the first one. so far very happy. i feel this fluid is better than the OE mazda fluid.

Ma transmission avait de la misère à se rendre sur le dernier rapport, depuis le changement d'huile, elle fonctionne comme une neuve. De plus les contenants flexible simplifie beaucoup la vie lors de l'entretient. Merci Amsoil!

Drained and filled 2015 honda odyssey, had that low rpm surge. Went away with 4 qts, will drain and add 4 more quarts after some miles. Immediately improved driveability.

Truck shifts much more smoothly, and with way less slippage.
