5.7L V8 Auto 4wd trans (4L60E)Changed trans fluid/filter/seal/gasket. All good. Noticed rear TRANSFER case "dripping" fluid. Removed plug and "milky/red/white" fluid drains...only about 1/2 quart. I replaced w/ Dex6 Trans fluid. I put back in 2 qts. Tiny leak, ok a year ago, now the thing is "dripping". I get up in there and with a white cloth and cleaner, and clean the whole thing to find a hairline crack, and I mean a hairline on the back side above but not in one of the bottom bolt housings. I put EPOXY on it for now. Other than replacement, any ideas on sealing? Can I spot weld or solder it? Any ideas appreciated.
Transfer case leakage UPDATE...Looking for ideas.... on 1999 GMC Yukon

Replacement of the cracked transfer case would be the best option for your 1999 GMC Yukon.

I am beginning to think that. JB Welded a hairline crack together & RTV Black Gasket seal around the seal. We will see. R
