After my trans burned up and the shop put in some cheap crap in it (they only have to worry a year) I decided I want to put synthetic ATF in it.
I went to the parts store and they had 2 brands. Valvoline +4 which was the same price at Mopar dino brand of about $4.68.
Then they have Mobil 1 "multi-vehicle" ATF which only states "Mobil Multi-Vehicle ATF is also suitable for use in both newer and older Chrysler applications " at a price of $6.xx
While the Valvoline bottle states "Designed to meet the specific requirements of Chrysler, Dodge & Jeep vehicles."
Though I know Mobil has good reputation with oils, my gut feeling had me go with the Valvoline.
And anyone here used Mobil 1 5W-40 Turbo Diesel Truck oil? Good for Cummins or too light?
