Are there any 700R4 Gurus here?

Hey, Ive got a 350/700R4/np321 in my Wrangler and Im losing trans fluid from the trans and gaining it in the xfer case where it leaks out of the rear seal. The xfer is from an S-10. I thought there might be a seal at the trans output, but there is not. So is my problem with the xfer case? Is there a bad xfer case seal thats letting the fluid in? Or should it not get out of the trans? I was losing about 2 quarts per week until I cracked the trans output shaft housing and I started losing about 2 quarts per hour. Any help is greatly appreciated!

Thanks,
-Blake

Its been awhile since I changed the tranny in my S-10 blazer but I do believe there was a seal in the tranny at the rear. My book isn't showing it but it does show a seal in the adapter that mates the tranny to the transfer case.

I believe there should be two seals in there, One in the trans/t-case adapter, and one in the input gear retainer housing of the t-case itself. I've heard that that is a fairly common problem though with the trans leaking into the t-case... might make sure your trans vent is clear and working properly (It might be building too much pressure in the trans and pushing the fluid through the seals.

As it turns out, the seal is on the xfer input shaft. And, that seal is all that keeps the trans from emtying into the xfer case. I changed the seal and everything is fine. Thanks for the help.
