I've always used Mopar ATF +4. Just take your own container and buy it from the dealers bulk container. It way cheaper that way. Besides, its ATF. Unless you have a diesel with monster power, does anyone really need aftermarket ATF? It's not like you'll get better MPG's, and power. I run RP in my axles, and Mobil 1 in the engine, so I'm not against aftermarket brands.
On another note, with chrysler transmission history, so you want to chance anything in there but the Mopar stuff? I change mine every 15k and the filter every 30k. my trans temp never gets above 150deg in the summer here in Michigan. Just my $.02

 

Cheers for the advice weedahoe and RubberFrog. I guesss it's just the dealers trying to stiff me again, as RP is SOOO much more expensive than the Mopar atf+4 over here.

I use valvoline, same stuff as the mopar atf but cheaper.

 

precisely why i got that this time around instead of RP.

 

My local WalMart sells Mopar brand ATF+4, I think. I'll have to check the price on it next time I'm there.

 

Could i use Royal purple for my 4.7L? because i would love to hop on that train. Would i notice any changes from the regular oil i use now(which is really cheap oil) if i switch to royal purple?

 

I use Royal Purple in my 07 4.7 every oil change.

 

Our Trannys will suck no matter what fluid you put in them!

I used Quaker State ATF+4

no probs

 

is my tranny goin to screw me over later? i thought that was with the 1999and lower model rams!

 

I have a 2006 Mega cab 2WD Hemi (545RFE) with 60k miles. I have a friend that likes Amsoil oil & transmission fluid. The wear tests appear to support his opinion. Any other opinions out there?
