We changed from a non synthetic transmission fluid to Amsoil OE Fuel-Efficient Synthetic Automatic Transmission Fluid and the transmission acts like its brand new. It shifts much smoother and stays about 10 deg cooler

drained and filled 2 of my primary vehicles with this product.

Changed out the transmission on a ZF 6 Automatic, didnt power flush but charged more than 75% with a new filter/pan. Dropped the operating temp by 10 degrees. This isn’t the signature series ATF but it’s every bit as great and will work amazing. Knowing Amsoil is protection this very expensive transmission is a relief. NO AUTOMATIC OIL SHOULD BE LIFE TIME. Change it with Amsoil and sleep at night.

Very excellent product

Great oil and keeps transmission running cooler which is great cause I pull some heavy loads at times on the farm.

I haven't purchased an AMSOIL product I haven't gone back to yet.

I have found amsoil to be the best on the market after first using it in my Harley. I am in the process of changing out all fluids in my '88 iroc that I have recently purchased this past summer.

Did my 2012 GMC sierra 6 speed and immediately noticed better shifts and lower temps in the trans. 96k and expect 50K more. Did my 2016 fusion and immediately felt better shift quality.

It cleans an engine just like it say. Was very impressed. Not my first use.

I feal if you want your car or truck to last a long time you should give it nothing but the best in lubrication

Purchased for a VW/Audi 09G transmission (Aisin tranny also used in Toyota/Lexus). One of the few lubricants that meets both VW/Audi spec G 055 025 and the Toyota/Lexus T-IV spec. Less than 1/2 the price of the OE fluid and I don't notice any difference in the driveability of the transmission--even in freezing cold winter temps. Can only rate 4 stars for the moment: lets see how it stands up after 50,000 km.

This transmission fluid is the best for my bmw 550i

ITS GOTTA BE THE BEST ITS AN AMSOIL PRODUCT.

Get your self some ! Just drain out or drop the transmission in the transmission pan about 2-3 quarts and replace with amsoil and just that little bit of the new mixed with the old transmission oil you will see a difference/then drive for 2to 3 months and repeat process my Tundra 2006 takes 12 or 13 quarts so I rotate out 2-3 quarts at a time with new amsoil synthetic

Excellent choice for any automatic transmission, just rebuilt a GM turbo 350, and installed this for the oil.

What a great product! I have always maintained my vehicles myself. Generally, I have used typical brands found at OTC / off the shelf products. I recently had read about AMSOIL recoomendations on a Toyota board about how it made their truck shift better / more smoothly. Does it you may ask? Yes it does. There is a night and day difference between the before and after oil change shifting performance of my truck. Thanks AMSOIL!

It's one of the transmission fluid that I have used. I have to be honest about what I do, I'm (OCD) about my cars just for instance my transmission says life time, but I know better no such thing & I have used the transmission fluid when I bought the car new, I change the transmission fluid every 20,000 miles & filter my fluid is always nice red in color all the time, & my oil is changed every 5,000 miles my car has never been the shop as of yet so yes I spend more for my maintenance than most that's me. I do love Amzoil I every product that I can transmission, oil, antifreeze & brakes fluid & grease. I hope others will take this & seriously lookin to Amzoil & try it It's great.

Great transmission fluid works very well/I want 3 more bottles and free shipping would be great

Had questions regarding the type of transmission fluid I should be changing out in my 2011 Buick Regal. The manufacturer (GM) had their 'approved' version yet I was wondering which product would be the most compatible with my cars trans. The fine folks at Amsoil pointed me in the right direction. Using that suggestion did not disappoint. The OTLTP took away the 'fish-bite' along with the downshift flaring I was experiencing before changing. I flushed the lines and ran through twice the amount of product just to be sure none of the old fluid remained in the Buick. That I felt was well worth the time and money. Now I'm not saying that other manufacturers of fluids couldn't do the same but all of Amsoil's products including this particular one have certainly impressed me. Thank you for the terrific support.

Had my mechanic do a complete service/filter change in the automatic transmission in my '95 Ford F-150 recently. This is a stock 2 wheel drive truck, and changed the transmission to Amsoil a few years ago. He determined that the transmission is in great shape especially to be over 26 years old. i just purchased a few extra quarts because i acquired a larger stock Ford transmission cooler from a trailer towing package equipped truck and requires an additional quart. Fine product
