    Whatcha think? Very slow drip. Tranny leaking into the transfer case?

    Got a Eibach stage 1 kit and it’s a pavement princess, this has nothing to do with that, right?

    Check the coolant bypass pipe on the engine to see if maybe it’s leaking from underneath and going down . The fluid looks pink almost like coolant .

    Wish it was coolant, unfortunately it all oily. Driveway is also stained where it’s been dripping.

    Unfortunately it is. Transfer case shield was covered in the same oil from it dripping.

    looks like WS ATF. i'd check the torque on those bolts. if they are tight, you are probably going to need to reseal it. Not sure if it uses a gasket or RTV but either way, you will need to unbolt it. i'd also check for any cracks in the case.

    first thing i would do is clean it all up and see how fast the leak comes back, if at all. have you had your fluid changed or inspected recently?

    Looks to be a transmission leak from the rear seal. if its still under warranty id take it to dealer. If not its an easy fix. will need to disconnect driveshafts and connectors and 8 bots on tcase to get to seal but its easy to replace.

    There's an empty cavity of dry space above that seam where the trans and t-case meet. It's the output shaft of the trans that's leaking. The t-case will get pulled and new seal installed..

    I had a leak in the same place but it was gear oil, the t-case input seal was leaking. When I pulled it off a half quart of gear oil was filling up the space like a fish bowl..

    Yeah, I'm going to take it to the dealer. Just wanted to get my ducks in a row in case they deny the warranty since I have a lift. Hopefully they don't give me shit.

    Thanks guys much appreciated!
