Customer Ratings & Reviews

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.

Great place to buy oil and free shipping if you have membership. Great reviews from all I have read.

Makes my transfer case fluid changes so easy.

Super easy to use with squeeze packs. Similar price to OEM why not use it !

Best product I ever used

Have been using this product for years in my 2002 Toyota sequoia. I just drain and replace. 192k miles and still shifts like new.

Vehicle I own is a 2014 Silverado , did the transmission oil and filter change using AMS oil full synthetic ATF , highly recommend I feel like the trans torque converter has better engagement and gears shift smoothly.

Replace transmission oil and filter along with transfer case oil, always use amsoil products in my vehicles.

everyone of the amsoil products are great...in short, they are products that you can trust. I never worry that the amsoil product i am buying will fail or fail me. The service from my supplier is also great. I can count on instant shipping with no delays.
