Installed this in the 10 speed AT in my 2019 F-150. Shifts nice and smooth, a pleasure to drive.

Have this ATF in both of my vehicles. Shifts very smooth. Also noticed some improvement in MPG

It made a world of difference. Shifts better and seems to stay cooler. Used in my 2007 31 foot, E-450 Class C motorhome Torque shift Transmission

My 2019 GMC Sierra 1500 developed the dreaded 8 speed shudder after a couple years and 23,000 miles. I read the GM bulletin and made an appointment with the dealership. They were out about a month and a half. After more research and watching Don Smith’s video I decided to do a complete fluid and filter change. I asked a coworker about whether AMSOIL was worth the extra money and he said it was all his racing friends used. I decided to bite the bulletin and do a complete Amsoil fluid change, engine oil, rear end, and transmission fluid and filter. Flushing the transmission through the cooler lines was a struggle but well worth it. The truck drives better than new. It is quieter and smoother. My wife noticed it immediately. Very happy with my decision to go with Amsoil.

Had this fluid changed for about a month. Can tell my Allison trans is shifting much better so far. I am very happy with the signature engine oil and gear oils I've bought as well. May have to change out my heads soon so I'll know more when I do that.

All I use in everything

Changed the ATF on our 2020 Ford Ranger at 20K miles. Got rid of the dreaded lag downshifting in higher gears that most owners complain about. Upshifts and torque converter lockup is much smoother. Amsoil has the best lubricants on the planet. I have converted all our vehicles to Amsoil products. You get what you pay for!

I shoulda coulda would’ve used this trans fluid sooner if I new it would make such a big difference on my jeep Jku it shifts smoother and quieter so far happy with everything amsoil

Purchased with 136k and transmission had some shutter and hard shifts. Changed fluid with Max-Life and Lucas Fluid Conditioner, got better but still shutter and erratic shifts. Did a fluid change with Amsoil Fuel-Efficient 10k later and it got way better. Now at 156k did the second change with Amsoil and all trans issues are gone.

Needed a service on my 16’ tahoe transmission, went online and found by vehicle the right fluid I needed, works great!

Best assurance i know of. I sleep better known its my vehicles are all maintained

Shifts are smoother Wanted this oil for its high heat ratings as I will run our car to Mexico

Have a 2017 Chevy Colorado with 8 speed transmission. Had torque converter and fluid replaced under warranty for transmission "shudder" at 9000 mi. Now after 5 yrs, 32,000 mi, out of warranty, "shudder" had returned. Decided to extract fluid from transmission pan, replaced with Amsoil Signature Series Fuel-Efficient ATF (Blue Label). "Shudder" is now gone!

Transmission runs smoother and quieter

Transmisión shifts smooth

Second time I have changed my transfer case oil. This oil seems to outperform the OEM oils. Changed at 5,000 km and now again at 133000 km. I always follow the fact that oils are cheaper than new parts. You can pay me now, or pay me later. Most people only change engine oil, and never think of transfer cases, diffs, and transmissions

Received the item super fast!

Recently did a transmission fluid change on a 2012 ram 2500 Cummins, you can already feel it shifting smoother while driving and shifting gears. The bags make the change easier being able to hold them in an orientation that doesn’t spill all over the engine or driveway.

04 dodge ram 1500 with 545rfe trans 280000 miles is new again with the help from amsoil. i have used other brands in same trans and can tell a difference with amsoil.
