is there any recomended length (time/ miles) to change you tranny fluid?
i am going to change the tranny fluid i was just wondering if they are all the same or is there anything i need to run since its a diesel... thanks

 

Depends on service duty. If it's all highway w/ some stop and go, every 30-40k. If yo do a lot of stop and go and towing, every 15-20k. ATF+4 is the required fluid. Mopars' is Valvoline, but you can run pretty much any brand of ATF+4.

 

nice thanks for the info and when i am cheking the fluid the truck has to be running or something like that right?

 

Yep! Running in neutral

 

20-30 thousand miles.
