Royal Purple is what I run in my stock piece of crap transmission. My tranny temps seem to be running abit lower but there is no programmer currently installed on my truck.

Did you take the transmission out and drain it? If it's still in the truck, then your transmission oil change will be 4-7 quarts, not 17.

1st dodge.......

if u looked in the book at the capacity of the trans that the whole trand w torque converter and everything. with just a pan drop and fluid fill you will only need a few qts.

any full synthetic fluid will be fine. I dont see how u can justify the over twice as much cost from one full synthetic to another.
$3-5 sure but over 2X no
