Because of some confusion between the owners manuel and the warranty book I went to the dealer the other day to try and get the answer. My owners manuel says to change the fluid in the Aisin transmission every 30,000 miles, (I am getting close) the warranty manuel says to change it every 60,000 miles. Turns out that the warranty book is right. Under severe service, heavy towing ect, it is changed every 60k. Under normal duty the fluid is changed every 120k. Sounds like they are fairly confident of the Aisin transmission. Good thing the fluid change is 60k, they don't even have any filters in the warehouse in Dallas. The filters cost $101.00, the gaskets for the transmission is not supposed to be reused and a new one cost $48.00, and the fluid cost $9.60 a qt., it takes 8 qts. A fairly expensive operation, don't know what the dealer might charge for doing it. I'll be doing my own.

The transmission has held up well this winter, I hope it will do as well this summer in south Texas when it gets good and hot.

 

What is it using for Tranny fluid....as ATF 4+ is like $5.75 a litre. Filter $101 and gasket $48 sounds like a pirates pricing. 60k miles per service is pretty good with severe usage. ks

 

The part # that is called for on the fluid is the same as the transmission, AS68RC. I'm sure it will be a dealer only item. I'm going to check with my Amsoil dealer and have him see if we can use the Amsoil fluid.
