I'm going to service my 2001 Durango transmission. I went to the auto parts store and they tell me I need ATF+4, but they don't carry it and can't even get it yet. My question is where can I get ATF+4 and do I really need it? Can I instead use ATF+3, and if I use AFT+3 will I need some sort of additive and what kind and where would I get it?

Thanks,

Dennis

 

use only atf+4 accept no substitute. It can only be found at the dealer.

 

thats BS. the auto store by me sells mopar brand atf+4.

 

I don't think it matters where you get it, use ONLY what the manufacturer recomends. I highly recommend that you read this website about transmissions and trans axles. http://www.allpar.com/fix/trans.html I read this while looking for possible cures for my car problem. It reinforces a lot of what I already knew. A lot to read, but good stuff.

thats cool that they carry it nick but that is few and far between and its still mopar fluid.

 

true. what about that 9 dollar a quart amsoil synthetic trans fluid?

 

ATF+4 must be bought at the stealership only... I would NOT go with +3 if the owners
manual says to use +4.

DC's auto trannys got enough problems now.. DON'T give the stealerships still
another excuse NOT to honer a warrenty.

Why do you think DC no longer has the 7/70 plan, just the 6/60 now?
Mainly it's their JUNK transmissions!

 

amsoil is a great product but thier suggested fluid is thier universal fluid.

 

you can use atf 4 in an atf 3 system but not the other way around. if you can get it at a parts store that is great because you cant get it but in a dealship down here. there are more synthetics that the newer trannys need in the atf-4.

 

I have to disagree as far as the quality of Chrysler's transmissions. Chrysler transmissions are very reliable if you do the transmission fluid flushes every 30,000 miles. I know lots of people that have over 200,000 miles on their original Chrysler transmission. I'd go with ATF+4 just to be safe, it is a better quality fluid with more additives such as anti-foaming which helps it last longer.
