After 30k miles, Ive drained and filled with OE-Efficient ATF 3 times. Ever since then, I drain and refill once every 15k miles sknce I drive 30k miles annually and do it every end of May(before summer starts) and beginning of November(after summer has passed). I currently have 180k miles. Every drain and fill, fresh fluid always comes out and I barely have any metal pieces on my magnetic drain plug. At this rate, my transmission will last forever. My car never slipped. Changing gears is extremely smooth like butter. I will never use any manufacturer ATF ever.

good oil

Love amilsoil products been running them in all my vehicles for 5+ years!

Recently put a good used transmission in my tundra and used a cheaper ATF (maxxlife) for the first 2-3000 miles along with a Magnefine inline filter and after switching to Amsoil the gear shifts, fluid temperature and cold morning drives have been noticeably improved. When I did the fluid change I cut the Magnefine filter open and the filter was clean and very little metalic buildup on the magnet. I will only use Amsoil products.

I had to replace my transmission temperature sensor in my 2008 F-350 with the 6.4 liter engine. So I went ahead and replaced the fluid and filter as well while doing so. The product is working great, providing a smooth shifting experience.

i have used several different amsoil products for about 20 years motor oil for motorcycles and pickups all my vehicles use amsoil products and only amsoil products any fluid that goes in them is amsoil yes it is a little more expensive than others but as i have learned in life you get what you pay for and amsoil is worth every penny the people that work there are very polite and helpful if you have questions never had a problem with amsoil but did have a problem with one delivery ups notified me a package was not being delivered due to damage i notified amsoil about it and they shipped a replacement package the same day did not wait for the return of damaged package to them when they received they the damaged package they determined that the damage was caused by mishanding during shipping very good company and people to deal with i have recommended them to all my friends

Use this ATF in my Dodge Ram transfer case. It shifts smoother than original fluid. Highly recommend it.

Purchased a 2.5gal jug, plus 2qts. To refill transmission on my 2018 GMC DURAMAX after installing a BANKS Ram Air transmission pan,which calls for a 12 qt refill. Fluid level is spot on and I think the transmission shifts smoother. Will be curious this coming summer camping season when I start towing my RV (6500lb travel trailer) throughout the Southeast where transmission temps reached 188 degrees on several occasions last summer!!!

Just like all the rest of Amsoil products, the is great transmission fluid!!!

I use this transmission fluid in 2018 Highlander 70000mil and 2007 Infiniti M35 176000mil. No problem both vehicles running perfect. I'm using Amsoil long time not just for transmission but for engine to. Grate product.

I’m gonna be honest, amsoil oil is the best around. I use it on all my cars.

I used it in my 2007 nissan frontier 4x4 at around 150,000k and now has 255,000k and still running strong. I bought a 2015 nissan frontier and decided to do the same with this one. I'm sure I'll have great results as well.

I work in a lube shop and we buy cases of this atf mostly for use in dodge transfer cases due to the extreme cost of the Mopar transfer case fluid and the reasonable cost of this, which covers all of the required specifications. I also personally use it in my old GMC transfer case that needs GM auto trak fluid.

Fast shipping and fair prices

Absolutely the best fluid to keep your transmission shifting smoothly and no overheating. Towing a 6,000 lb trailer and shifts are solid, never any issues and trans temp stays under 225 degrees, even pulling hills in 100+ degrees. If you want the best, pay for the quality and avoid any issues.

I've used Amsoil products for some 20 years and used them in place of o.e.m products they are quite reliable and are easy to access.

Did a full fluid swap on my 2012 Silverado 1500 w/6L80e transmission when I bought the truck and it shifted great. Ran it for almost exactly 45,000mi and I do quite a bit of towing my boat with the truck. Might see 180-190°F trans temps on the hottest days of the year when not in the interstate. Just changed the fluid again and it’s shifting notably smoother than it was before the swamp. Can’t say if it is AMSOIL, regular fluid change intervals for it, and some transmission tuning by Black Bear performance but I’m the only person I know first hand that has a 155k+ mile 6L80e that hasn’t needed a rebuild.

This seems to be working good. This is the second year using AMSOIL (OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid) for a Ford EDGE. My Sport seems to shift faster, and smoother, but sometimes its shifts so fast, that it feel like a harder shift like a shift kit would give you. I down think this is bad, you just have to remember, ford has an adaptive shift learning stratagy to optimize performance, and paddle shifting can cause the Trans to act different, if you use it alot. Myself I try not touse it.

Used this in power steering and it is quiet and smooth.

Changed the transmission fluid in my 2017 Toyota Highlander at 60,000 miles definitely seems to be shifting smoother. Will definitely use it again at next change interval.
