I had a shifting problem, up and down on a 2019 Silverado 8L90 8-speed transmission. This transmission only had 45,000~ miles on it. Removing the prior fluid, changing the filter, essentially flushing the tranny with the BLUE ATF resolved any issues I was experiencing. The transmission actually shifts better now than it ever did, even brand new. AMSOIL Signature Series ATF is magic! Great stuff and I highly recommend it!

Shifting speed and smoothness improved, which was expected with a new fluid. But I really didn't expect acceleration to improve and it did. The transmission is quieter too, so all around, I'm extremely satisfied after 600 miles with the new ATF.

I am very particular with my vehicles especially my 2010 Camaro 2 SS. I wouldn’t trust anything other than Amsoil products. Been using for years and will continue

Serviced the Transfer case on my RAM 2500. So far all good.

This is best ATF I have ever used it made a world of difference in the shifting!!!!

i did 3 drain and fills out my transmission on my 2007 mazda 3 2.0 4 speed. i changed out about 80 % of the old fluid. i am happy with the performance, provides a little peace of mind. in the future doing drain and fills changing out about 2.85 liters of fluid out of a 7 liter transmission i might have done a couple drain and fills with the amsoil OE fluid and then the final one or two with amsoil signature series.

my 1998 chevrolet c1500 tranny was rebuilt at 275,000 km. presumable the transmission shop put in a decent quality fluid. I decided to do 3 drain and fills out the dip stick of 3 quarts each. i changed about about 7 of the 12 total liters. so far no issues. i will likely do a few more changes and switch it al over to Amsoil. provides some peace of mind hopefully a small reduction in drag of the vehicle.

1st time try in Seems to do very well onn130k transmission. Good stuff

Did a couple drain and fills to my 2007 mazda 3 with 160,000 km. Noticed faster shifting and better fuel economy. Very happy with purchase. Decided to do another drain and fill.

If y’all don’t already know that AMSOIL has the best lubricants then there is no help for ya!!!

Noticeable improvement with cooling and shifting

If this is not the most expensive stuff then it is the most expensive there is! I will use mink oil next time! And I have been saying the thing for the last 20+ years. But this will be the year when I switch to mink oil I promise!

After watching multiple YouTube videos of Eben Rockmaker on AMSOIL ATF signature series. I was curious about how it would work on my 2018 Dodge charger 392 Daytona. I had a drain and fill done only using 4 quarts of ATF @ 30K miles and since then my transmission temps have decreased significantly and shifting is a breeze. Absolutely good stuff, I can feel the protection!

I used this product for my 2011 ford focus steering system an is way better now, I'm really happy with this result.

Great product, had to get oil into a hard fill plug to access. Soft packaging made it easy with zero spillage. Oil is working great, highly recommend.

I have an older car and finding synthetic transmission fluid for it can be a challenge. Happened upon this stuff and tried it out. Night and day difference, feels like a newer car now. Quite pricey, but certainly worth the cost.

Been using Amsoil transmission fluid since 2016. Pull through mountains and flat lands with a 33’ camper, hot or cold weather. Transmission hasn’t had any issues. 2020 pull transmission to have refresh from years of heavy pulling through mountains. Tranny builder said parts look great. 5 years later replaced fuild first time since rebuild. Still smelt good. Stand behind the product.

I had the infamous transmission shudder on my 2018 duramax Colorado and I changed to the AMSOIL ATF fluid, the shudder is no more, and the transmission shifts so smoothly like its brand new. I am very impressed with this oil and will be using this in all my vehicles from here on out!

This is a great product. I use nothing but amsoil in all my vehicles and have since 2005..tranny, differentials, transfer case etc .

My gmc with the 8 speed transmission and it likes to shudder when driving through the gears and now after I have flushed with amsoil the shudder has been greatly reduced.
