tranny/tc seal questions

My 2000 dub has been leaking a couple drops a day of tranny fluid where the trans meets the tc for a while but it sat in the garage all last week and when I got back it had leaked probably a half quart on the floor.

My first question is where is the fluid comming from, I know some is comming from the trans but could some of it be from the transfer case? I know there is an output seal on the 42re but is there also an input seal on the front of the 242?

Second, how hard is it to change the seals and would I need any special tools(like wierd pliers or punches)? Do you just drop the tc and thats it or would it be easier to just keep adding fluid?

I have actually seen were both seals went bad and the TC literally filled up with ATF. The big puddle is indeed coming from your tranny if it is coming out the weep hole where the TC and tranny meet.

yes there are seals on teh output of the tranny and the input of the tc. Easy to replace, just unbolt teh driveshafts, and remove teh 6 nuts holding the tc tothe tranny. Disconnect the wiring to the tc and the shift linkage and lower it with a jack. It is heavier than it looks. I had mine out in 15 minutes to do my hack n tap. Probably 30 min to put it back just because I decided to manhandle it putting it back in.

You can buy a seal puller or what i do is drill a small hole in the seal itself and use a dry wall screw to pull the seal out. Just try not to mar the surfaces around the seal with a screwdriver or anything like that.
