Just like the Title says.
You folks that have them. Lets here about it. How many miles you got and what's your fuel mileage.

 

Aisin is doing fine, 229,000+ miles, no problems. Fuel, 10 average, loaded and unloaded w/ 40 ft Pro-Trak. 15-16 w/ no trailer. Really don't know what mileage has to do with transmission. Don't use Amsoil in the Aisin or do it at your own risk.

 

Thank you for your reply.

 

Whats the deal with Amsoil and the Aisin? Is it a WS fluid?

 

I don't know what a WS fluid is. I called Amsoil before I changed the fluid the first time and got a service rep. He told me to not use the Amsoil automatic transmission fluid in the Aisin transmission. I was planning to use it. I use it everyplace else.
