Transmission leak

[Black Creek]

I have a 2007 GMC 1500 crew cab 4 x 4, 5.3 l.

When I checked my tranny oil it showed low, there is no evidence of a leak. The service manager at the local shop said it could be the seal between the tranny and transfer case and that is where the extra oil is going.

 

Has anyone else had this problem? Any thoughts?

 

thanks

I'd check the transmission oil cooler lines going to the rad first. Very common on these trucks to start leaking out of the crimps.
