Transmission oil leak?

So I got home from work today and noticed about an 8 inch diameter oil spot on my driveway. Crawled under the truck and noticed oil leaking from the back part of the tranny but it was hard to tell exactly where. I took it to ford so they could put it on a lift and take a look. They seem to think it's coming from the seal between the transfer case and the tranny. So here's my questions:

1) Should that seal be the culprit, how big of job is it to replace?

2) I'm heading out on a trip tomorrow that's about 1400 miles round trip. Think it'll be ok until I get back?

What year ? My '10 had a leak at rear of trans and it was the pass thru connector on rh rear side got it fixed under warranty.

There is a TSB about this.

I would not suggest driving it

I Agree with Bulletnjm

Yeah, what the heck? No way I'm driving mine down the block with a trans leak like that. Get that thing in the shop and get it fixed already!!!!

I found a TSB on a bulk head connector. It's probably that but still could be the seal between the transfer case and tranny.

Odds are it's the bulkhead connector. Common issue on the early ones. Dealer will take care of you.

I did the bulkhead seals on mine this weekend. Wasn't too bad. Tasca has them for $6. Would get a filter from them too since you're dropping the pan anyway ($25). My drain pan had like 6 quarts in it but the transmission took 8. It shifts really nicely now though!
