Leaking Transfer Case Fluid

[Cosa]

I recently had my starter motor rebuilt, along with the cleaning of my injectors/fuel rail. Ever since i got the car back, upon some spirited driving, i noticed black fluid on the garage floor. It didn’t have a very oily texture, so I’m assuming its transfer case fluid.

I took a closer look, it drips down the front of the gearbox. Is this something i need to be concerned about? Does the transfer case have an overflow?

I thought i might also add that i have the torque split controller, however i do not set it any higher than 5 or 6 out of 10. For my day to day driving i turn it all the way down to 0. I also checked the reservoir in the boot, it is overfilled by approximately 1-2cm.

Yes there is a breather for both gearbox and xfer case. Normally it is bolted to the top bellhousing bolt just above the starter motor, so it is possible something was knocked then the starter went in.

but generally you would not expect the xfer case to breathe much, whether or not the breather is attached correctly.
