I didn't know Amsoil made a 75-110W gear oil. The 2012 owners manual states 75-90w for the getrag 226mm rear end with fiction modifier. I used Amsoil 75-90w severe gear oil and no friction modifier was needed as many differential oils already have the right amount included. Amsoil being 1 of them. I also have the Amsoil multi-vehicle ATF in the transmission and everything has gotten smoother to me. I tried Redline and didn't notice any improvement.So I decided to change out the gear oil in the rear end and change out the atf in the 6060. I used severe gear 75-110W in the rear end (with their slip lock friction modifier) and then the amsoil synthetic equivalent for the ATF in the manual trans. I feel like the trans is just as notchy as ever, it didn't help and may even be a little worse. The rear end has always howled (3.92) I am sure it is from getting pounded from having a kenne bell supercharger up front, but I was hoping to quiet it down maybe. Nope. Now it is starting to clunk when I turn the car every now and then.
Thinking I should go in and change it all back out-chrysler locking differential stuff and mobil 1 gear oil for the rear and mobil 1 atf for the trans. Feel like this is "snake oil."
Go get a bottle of mopar friction oil or ford and put in it. It may stop the clunk. cheap insurance that its got the right stuff in it. ive read labels on the stuff u buy with it in there. its just for topping off as far as im concerned.So I decided to change out the gear oil in the rear end and change out the atf in the 6060.
