4R70W Front pump gaskets

According to my Ford dealer, my car needs new front pump gaskets, a pump oring and a filler tube oring. My question: how many front pump gaskets are there to replace? I would ask him, but after he quoted me $870something to fix it I asked him to stop molesting my car and took it back. So how many of those gaskets do I need to order so I can fix it myself? Thanks,
Will

I believe there are 2. I have my new one at home, but can't remember how many there are for sure. If no one knows, I can look when I get home.

These are highly engineered precision vehicles, the first step in diagnosing the problem is to strike the suspected offending part sharply and repeatedly with a blunt object, then re-test.

That'd be great if you could check. I'd like to order my parts ASAP. Thanks,

There is a pump gasket, pump seal, and an o-ring around the pump.

So how many of each do I need, just one? Also, where exactly is the pump in the trans and how hard is it to replace these items?

There are 1 of each. The pump is the first thing behind the torque converter. How hard it is depends on you, I think it's easy. I have replaced pumps on a4ld transmissions so after that a 4r70w is a piece of cake.

Never done it before, but it sounds like a mighty good time to throw in a Marauder torque converter while I'm at it...

I ask this because the dealer says these are the parts that are leaking. Does that make sense, or is it just more dealer BS? There is a leak from somewhere north of the pan gasket.

I would install a new pump bushing and install a m/d reverse drum with the snap ring welded on if it were mine. Might be a good time to upgrade the intermediate clutches and put in a new OD band.

you basically will have to pull the drive shaft, and pull the whole trans down, then remove the TC, remove the bolts to the front pump.

Then you need a slide hammer, actually two works better.

Hopefully it is a replacable seal, instead of damage to a metal face.

If I were you I'd put in a mechanical one way diode/reverse drum, heck clutch packs if you have the time.

I'm not familar with the weld on snap ring, but I used a spiroloc - G lock ring to retain the reverse hub, which is far less risk of coming loose at high-rpm compared to the stock snap ring.

Anybody have p/n's for the two gaskets and o-ring? from http://www.bulkpart.com

Not sure if these are correct, they are listed for the AOD-E and the AOD, still missing one gasket.
