Manual Transmission fluid leak

I replaced my transmission a couple of years ago with a use one and it always had a very slow leak between the transmission and the tail shaft housing. But recently it has started leaking a lot more. Im going to be pulling the transmission to replace the slave and master cylinder and to install a manual transfer case. Is it possible to just disconect the tail shaft housing and replace the seal to solve the leak or is this a more serious problem?

Here is a pick of where the tail shaft housing connects to the transmission.

you cannot use your present output shaft 4wd tranny to transfer case output shafts are shorter in length

the tranny must be dis-assembled to install the shorter output shaft

Huh? All im asking about is removing the tail housing to replace the seal between it and the transmission and then bolting it back on.

You can fix that leak (which is a common one) by draining the transmission, removing the transfer case, removing trans crossmember, then removing the tailhousing. Cleaning everything up and resealing it with a thin layer of gray RTV silicone on both machined surfaces, bolting them back together. Wait about and hour or two for the RTV to harden up, then refilling the trans. This is how you replace the tailhousing to trans seal on a manual.


Since you are planning on new clutch and slave cyl, it's easiest to do the fix while the trans is out of truck. Process is still the same.

I had a very hard time reading this... Next time try to make it clearer for us to read by using punctuation and complete sentences...

If I read it as typed and submitted, none of it is true. The transmission doesn't need touched if he installs a manual transfer case. He already has a 4x4, why would trans outputs need swapped?????

The only concern area is a: does his tailhousing have threaded bosses for the manual tcase linkage and b: the front output of the tcase will determine what front shaft he'll run. Most if not all 98-00 manuals already have the threaded bosses for the linkage. If he's going to run a 90-97 tcase, he'll need a 95-97 Explorer shaft. If '02-03 Ranger (FX4LII) tcase, his stock 98-12 shaft will work just fine. Rear shaft is a non-issue here.
