Just got a 2022 3500 with the Aisin. No where can I see the trans fluid and filter has ever been changed. I’m at 59,000 miles. Good thing is Im not part of the Aisin 2022 failure but I also don’t want to be. I see amsoil is recommended online for everything in the truck but the transmission. Online says only Mopar. Is it really an issue?? Amsoil has the signature series and OE formula. I can’t see why both wouldn’t work and I’ve seen people online use amsoil so…?
