Getting ready to change the external tranny filter and fluid this week,and seen my ford filter doesn't have an o ring.do I need a new one or can I just order. New from ford.

 

If you got the MC filter it doesn't come with one. I haven't changed my o ring yet with no probs. I'm no pro and don't know how many changes you should go with out replacing the ring

 

I wouldn't change it without the o ring. I have several vehicles that I change out an oil element filter and every time I didn't replace the o ring... A leak.

 

+ 1 .

 

What o ring do you order then? Wonder why the filter doesn't come with one

 

I see this one comes with a ring. http://www.dieselfiltersonline.com/N...z-09-C09b.aspx. Is this a ok replacement to motorcraft?

 

Ntz makes that filter for ford it's just repackaged,I think the part # for the oring is 3c3z-7j126-aa

 

Picked up the NTZ from local Napa.It came with the o-ring.Around $20.00.#17026

 

Because someone took it out of the pkg. I haven't seen any suppliers shop without an o ring, especially Motorcraft.

 

Yeah I ordered it from diesel filters online. Just got on and looked and they say right their that they don't come with the o ring.

 

Dieselfiltersonline does ship with o-ring for the NTZ filter. I have purchased 2 from them.

 

Yeah I saw that. I got the MC filter. I will be ordering the other one today

 

The o-ring does not come w/ the Motorcraft filter for some reason.

 

I would go ahead and use the MC filter with old O ring and if it leaks then go to Ford and get their $5 O ring. Most it'll cost you is 8 oz. of fluid. Coat the old one with a little grease and put her on. Wrist tight is plenty. The O ring does the sealing not the threads.

 

Yeah I changed the filter last week. Hasn't leaked yet. So I'll just keep an eye on it.
