I’ve been using this fluid for the past 5 years in a dedicated track car (C6 Z06) with a T56 and now a TR6060. Both transmissions are running carbon blocker rings and this fluid by far has been the smoothest shifting fluid I’ve tried. I will also note during heavy track abuse, just switching to this fluid has dropped trans temps about 15 degrees.

When it comes time for a transmission service this is my fluid of choice, recommended by the manufacturers and works great!

This is fluid that I use for mine and for customer’s vehicles that are wanting a fluid that meets the TES 295 standard for Allison transmissions. If you have a GM vehicle from 2001-2019 equipped with an Allison 5 or 6 speed transmission, then this is the fluid I’d recommend from the Amsoil product line

Quality products , quick shipping top notch as always

I have always used this oil in my aliison transmission has worked great

Love it

Truck loves it: smooth shifts, lower temps, over all happy with purchase.

I swear by all amsoil products in all our vehicles...my wife's tahoe..my hd work truck..my equipment and my toys...I was figuring out my options of either a rebuild or getting a new tranny..transmission wasn't quite shot but I was noticing some sloppy and rough shifting after a long plowing session...I took a shot and tried it..and it 100% turned it around..Allison transmission.. filter change and put in new fluid..almost immediate results..was amazed..drove for a couple weeks and did it again..transmission is better than it ever was...runs wayyyy cooler and I also gained some serious mpg back...

I use it in my 6 speed t56 (Corvette) and have had great luck with all AMSOIL products. This Vette is used for racing only.

I use this in my motorhome and my pickup.

Smoother shifts lower temps. Everything could ask for

I put this in my Tremec 6060 and it made it shift like a tractor. Put my regular fluid back in it and it works fine now.

The trans appears to be working much smoother.

Manual transmission in my CTSV

it made my ZF 6 speed behind my Duramax. shift much easier and smoother

There is so much time spent on testing this product,That's why I feel that I can completely rely on the Amsoil line of products.

I use this trans fluid for street and track use. During track use in Florida I see temps hovering around 250 F on my transmission. During inspection of the fluid after the track day... it looks like new. I've been using Amsoil products for 25 years now and would NEVER use anything else on the track!

I be installing this trans fluid in a 2001 Silverado 8.1 that has an allison . This is a 1ton Dually that pulls a fifth wheel travel trailer. Looking forward to it running cooler and smoother. I have watched several you tube videos on how to change it So as soon as it's not cold outside I'll give it a try.

I became an Amsoil preferred customer after first finding a dealer and buying the product for a year for all my 3 vehicles. I liked it so much i recommended it to my friends and family. My three sons all use Amsoil and they contact me in AZ. I place the order for them on line, have it shipped to them and they pay dear old dad for his experience. I have been successful teaching my sons and grandsons the value of preventative maintenance and using Amsoil products.

Used this in my allison transmission and it actually runs smoother. The best part about it is transmission runs about 20 degrees cooler than it did before.
