have an 05 fx4 the transfercase is leaking out the rear output shaft put new seal in and it lasted about two weeks and its still leaking to day i decided to change the fluid in it and when i took the fill plug out about a quart of fluild came out is there any way fluid from the trasmission can transfer into the transfercase thanks

 

i believe the transfercase is suppose to have about two quarts of fluid in it

 

ya they told me two quarts but i took out the fill plug not the drain plug and when i took out the fill plug i got a bath of atf

 

too much fluid would definitely screw your seal up, did you ask the dealer if your transmission could leak into it
