I have a Dodge 2500, 2006 5.9, with Auto trans.
The manual does not show the capacity of trans fluid.
I did a search of the forum, but didn't come up with that particular number.
Anyone know?

 

Pan drop, filter change, and refill is 4qts according to the FSM. Get 6 qts to be safe though. It has always taken me more than 4qts.

If it's a rebuild and tranny is dry, then anywhere from 14.5 qts to 16.5 qts.

 

I just did a pan drain and refill this past weekend, was about 4.5 qts.. luckily I installed a drain plug on the previous service..
