Used exclusively in all my Cummins diesel trucks. 300,000+ miles on them. One just recently had transmission rebuilt only for OD issue, and other has never been opened up. Superior performance in the high desert heat where I live, and long service intervals between changes. Always stays red!

Put this in my T case. Old oil was past do. This fluid got rid of some noise in the cabin. Works good. I'll see how it holds up this winter when I use 4x4 the most.

I bought x2 of the 2.5 gallon jugs. Added a deep pan to the 4l80e in my '03 Chevy 2500 and wanted to add fluid and also get some of the old fluid replaced. Kinda doing a partial flush with the Amsoil Dex VI. I'll go back in the transmission in about two weeks or so, drain as much fluid as I can, add new filter and top it back of lf with Amsoil.

Amsoil products work great! The tranny shifts smoother.

I read reports that people started having issues with there 9 speed transmissions. At 52000 miles I noticed the same. I also read that the transmission was
serviceable. lol After buying Amsoil and a ram filter I discovered that serviceable meant 17.5 hour job that. Required removing transmission bolts to break transmission in two pieces.
I choose to drain as much as I could just shy of 4 quarts. Instant improvement with shifting and drivability. Awesome stuff as always.

Used it on a 2004 honda civic transmission feels like its brand new. With perfect shifting. I did a complete drain and fill 5 times. 50 mile increments. Too clear out old now i just do one drain and fill every other oil change around 10000 miles. I am getting my money worth out my highway beater. 260000 miles on trans. And still going

Great fluid, felt a difference instantly when replaced old fluid with this. Smoother shifts both going into gear and when changing gears on down hill grades. Great stuff.

Lovin' it! We'll see how it does over the long haul, but had numerous transmission shift fault
codes, neither led myself or a more experience gearhead to believe the tranny in my Chevy 2500 HD was failing, just had some intermittent quirks. With that, I made the shift to AMSOIL when it was decided upon to change the tranny fuel, especially not knowing if the reseller business had performed the task since the Chevy was nearing 50k miles.
Went with a deep pan and filter, added LOTS of AMSOIL tranny fluid, and no more intermittent fault codes, slightly better gas mileage, better shifting, and lower tranny temps.
Purely not saying AMSOIL is a tranny repair recommendation, but in my particular case it's all relative.

One I call the best of all oil never had problems. I have 2017 Malibu my car rans okay & rougher be for I changed oil I took my car to be tested on a dino, I think I spelled it wright if not sorry anyways found with the oil I had in the car at running at 80 MILES my RPMS WAS 3200, After changing to Amzoil at 80 MILES RPMS dropped 2700 to me that's a big difference the other oil that I can't say is one of top brands.

I put this fluid in my 2013 Suburban for the 100k fluid and filter change. I have noticed that trans temps are cooler on average, and while towing. I also have noticed improved 2-3 shifts, where it was hesitating before the fluid change.

I had a couple of hard shifts and decided it was time for another transmission flush on my Tacoma with 205k. I had 2 previous flushes with Toyota WS fluid which worked great but wanted to try Amsoil this time. 12 quarts and 5k miles later and I haven't had any problems shifting! So far it feels/shifts like it did when it was new. I will be doing a flush on the wife's car soon and will try the Amsoil SS.

I drained and refilled 4 times, driving a few days in between each change. It cleared up the shuddering on my Honda that has 240k miles, giving the transmission a new lease on life.

I have been using Amsoil for 5 years in my 6.7 cummins. Truck runs great. My 2011 ram with 6.7 has 300,000 miles on it. I change the filters every 20k and the Amsoil every 40,000 . The engine has been bullet proof . GREAT PRODUCTD

Full disclosure. I don't know if Amsoil is the best oil on the market because I'm not a chemist. But I do know that I trust the Amsoil brand more than any other in the industry. When it comes recommended by guys that push 2k+ hp through their Cummins, I trust it will be just fine in mine. I will continue to use Amsoil exclusively in every component of my truck because I believe it's the best I can get.

Makes the Taurus shift silky smooth!
Reviewed by Rich:
My job requires me to travel extensively, as I traveled from the mid plains through the divide I noticed some harsh shifting, as the Taurus approaching 60000 miles I decided to replace some of the transmission fluid. On the next trip the following week, I was pleased with the reults, Silky is the term I wanna use.

I spent $6000.00 to make sure my Allison will handle 1000+ plus horsepower and 1600+ lbs/ft of torque and so far Amsoil OE trans fluid has not let me down!! I change my fluid every 50.000 miles and it comes out looking just like it went in, trans performs exactly like it should! I have used Amsoil in this truck since the first time I changed all of the fluids at 25.000 mi. Absolutely flawless performance! 07 (Classic) GMC 2500HD CC with a 6.6L Duramax diesel currently at 700+ hp and 1100+ lbs/ft of torque with 162.000 mi. My son has an 04 GMC 2500HD CC with a 6.6L. Duramax in it with 350.000 mi. and nothing but Amsoil lubricants in it, Stock motor and trans, Body is a little rough, but engine and drivetrain are flawless!!

When I need a product that you don't need very often, i.e., ATF, I will always go to Amsoil because I can trust the product to be what it is supposed to be and more. I will always trust all their products to not only protect my equipment while it is operating but to protect it while in storage from corrosion.

My trans has over 200k miles on it. After the service (I did myself). the old trans feels really strong. I was having some hard shifting when it got hot. That went away. I should have switched to amsoil 150k ago. I use amsoil in my Harley and Indian too. I use amsoil gun oil.

Used lots of Amsoil products over the years, from my Ford Powerstrokes to my lawnmowers. Always had good use and performance from them. Will absolutely continue using Amsoil products.
Reviewed by Jay:
I am not a chemist or engineer, so I cannot speak as to what's inside the bottle. However I am a mechanic and can speak as to what's inside a engine, transmission or differential. I've used Amsoil on and off over the years alone with other bands of synthetic and conventional oils. I've never used anything that didn't work. However, I've found good oils last longer. Being a fleet mechanic I change a lot of oil and get to see what it looks like under abuse. Amsoil always holds up. That's why I use it.

This car does not have a dip stick for the ATF and had about 90,000 miles and the fluid had a burn smell and very black. I had it changed even knowing if it had not been changed they felt it was better not to change it and the car runs great. Due to the fact that fluid was so bad I will change it again.
