Customer Ratings & Reviews

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.
