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.
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!
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.
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!
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
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.
Yes, I would recommend this to a friend.

2020 Ram 3500 with a 6 speed AS69RC. Shifts allot more quiet, cooler oil temp and sureness in making shifts. I have used this in various vehicles with very good results. It is also a very good oil for the transfer cases for 4X4 and makes them very quiet too. This was a fluid change only per maintenance schedule. I am doing oil analysis for this transmission.
Highly recommend especially if you have waited to long for a flush or change. I run in all my cars and trucks helps with smoother shifting and etc. I have a 2012 chevy cruze the tranny started slipping in 3rd gear I believe started using amsoil ATF fluid and 25k later its still running down the road.
