I did a trans flush when I drop the pan everything was clean with a little bit of a aluminum color light flakes normal wear so far so good it's been about 4 weeks

If you've ever had to change tranny/diff fluid in a tight space, you know how much of a pain it can be, even with a fill pump/hose. These easy packs make it super convenient to do the job as you can roll/crumple the container into any shape you need. I also like knowing I'm putting in the best fluid in my car that I can get.

At first, I was skeptical about Amsoil. But I"m here to say, once you try Amsoil other products will be mediocre. I like how my 2011 honda Pilot shifts. Very smooth. I intend to stay with Amsoil for all my maintenance needs. I just wish they have sales, to make them more affordable. Bottom line, Amsoil is highly recommended.

The transmission in my truck is known to shift harder than many people like. This definitely shifts smoother.

I have been using it for years in my Volvo and my son's Toyota. 325000 and 169000. We expect to get even more miles in both cars. Shifting smooth, no hesitation or slipping.

Put 8 quarts of AMSOIL Signature Series Multi-Vehicle ATF in my 2004 Monte carlo SS with the 4T65-E and 270K miles. Made it shift smoother and it feel better. Also gave me peace of mind knowing it has high grade ATF in it.

Since flushing my transmission and switching to this fluid I noticed a difference right off the bat. My car just drives smoother and shifts smoother. Like it got rid of all the friction in my transmission and made the engine not work as hard. It also runs cooler. Really unbelievable product. I run signature series ATF and motor oil in my car and it's 32 years old and runs better than most newer cars out there

Few years ago started having flutter noise in 2004 Honda Pilot transmission. Honda mechanic recommended full flush for $300 (It took 12 quarts but only holds 8.2). Have done that a couple times now and also drain and fill. It seems Honda fluid doesn't last long so a friend told me about AMS oil. I decided to try it with just a drain and fill of 3.5 quarts. Flutter is gone! Time will tell but for now I'm impressed.

Transmission temperatures are MUCH cooler after switching over to this fluid. I tow a 3,500lbs trailer and the temps are 10 degrees Celsius lower both towing and regular driving. Stop and go traffic is the worst on my transmission with seeing temps as high as 100 but won’t go over 85 on a hot summer day. 1500 Sierra with a 6 speed transmission, only replaced the transmission filter and refilled 6.5L of fluid. Happier than ever with this product.

Superior product for reasonable price.

This is a great replacement from OEM trans fluid, I could certainly feel the difference right away in how the car shifts and how it completely stopped buckling on certain shifts I would definitely recommend this to anyone looking to replace their OEM fluid

Changed the ATF in three of my vehicles to this product, all three seem to shift smoother than before. This isn't a mechanic in a bottle product, just keeps things running smoothly. Happy customer so far, all the Amsoil products I have used seem to be in a league of their own. I hope the trend continues as I plan to use Amsoil products for any lubrication needs in everything I own.

You can’t go wrong with Amsoil. Whatever lubricant you purchase from them you’ve made the right choice.

Highly recommended

Used in power steering pump. In single digit temps, much less whining on startup Lasted 1 sec. or less! Normally would take about 5 sec. to quit whining with a different brand. Steering seems to feel more solid?

Arrived early, so far so good, just put it in

My 6L50 had a transmission shudder in and I decided to try Amsoil. My shudder is completely gone now and shifts so smooth now.

These days warrantee's run out and most of the cars are made to have issues after 60k miles, that's why if you plan on having a car that runs past 60k Amsoil is the Insurance Policy for your Mechanical parts, I run in my Engine, Transmission, differential. You can afford it so can I because you change it less than Conventional Synthetic because it lasts 4 times as long. I check my oil every couple weeks for Color, Viscosity film between my fingers, and Level. As long as you keep up with those, you're good to go. I know because I check that this oil in the transmission will last 100k+ but I still change every 30-60k miles I ran it in my diesel Semi Tractor Trailer never had to change the oil ran like a dream gave me extra power and longer life.

This stuff works great! Highly recommend!

SIMPLE THE BEST MONEY CAN BUY.
