External Tranny Filter

[89MustangGX]

Getting ready to service the tranny in my 06 -- my first time, possibly the truck's. I've put together some parts -- I have an 08 Pan, 08 Internal Filter, Case of Mercon SP, and an FT-145 external filter (toilet paper roll).

To my surprise, the FT145 didn't come with a rubber o-ring, though it seems like the same type of filter setup as the oil/fuel filters that do come with o-rings.

Does it have an o-ring? Do I need to change it? If so, what is the part number to order it?

Also, what is the torque spec on the external filter cap?

Thanks,

Adam

I have never replaced my o-ring when replacing the external filter. Oh and I usually go a hair past snug for my torque spec. Not sure about Ford's spec, but mine hasn't leaked yet.

Thanks for the experience.

I would really like to find a torque spec though -- can anyone help?

I just looked in my ford workshop manual and I cant find any torque spec for the external filter...there is a section on changing the filter but no torque spec.

Be careful it's a PITA to get off usually, and I only put them on hand tight. Like maybe 1/2 turn after gasket/oring contact. Now they come off with a reasonable amout of effort, but they don't leak either.

The first time I removed it , it was a challenge to say the least. I was sure the mount or the cap was going to break.

The o-ring IS re-usable - it does not swell w/ exposure to Tranny fluid. I always change it anyway, just to be conservative.

Since the o-ring does the sealing, no torquing is required.

I use an impact wrench to remove it - that works well and the lines do not flex much in the process. I also use the impact wrench to install it, but I do NOT hammer it down. I stop immediately when it bottoms out.

I think I will stop by the dealer and get a new o-ring -- seems like a small price to pay to make sure there are no leaks.

About the torque -- makes me nervous not having a torque value. That's one of the ways I decide I actually did the job right.

Should I figure on about 20 ft pounds -- similar to the oil and fuel filters? I haven't looked at it to see if it is marked or anything, but I'd like something to go by.

Thanks for your help.
