I have a question with the 60,000 mile service for a AT transmission, I have a 2005 5.9L 4-speed auto. It says to refill AT and replace the filter for the trany, I have talked to othere that have the same and said they have never changed there AT trans fluid or filter becouse its a sealed trans, and then others that have said it is a must. I guess my trans is the 48RE, correct me if im wrong, so my question is do I change the trans fluid and filter or not.

 

Definately change it. Get the old dirty fluid out and some fresh in. It's a very easy do it yourself project.

 

You have 2 choices.
1) never change it and be mad when it dies.
2) change it. Would you not change your engine oil. Why does Dodge recommend changing it if its not required....

 

True true its as good as changed,
