April 18, 2008There is the assumption by many that using anything other than Chrysler ATF+4 in our transmissions will void the warranty.
As I said in my last post I just had a transmission replaced under warranty.
When the job order was made up I told them I had Amsoil in the transmission and wanted that in the new one.
It was no problem at all. It did not effect my warranty and they were happy to put it in the new transmission.
