Leak Transmission/Transfer Case Identification Help

[jastewart25]

Hi All,

Bought a 1985 Chevy K10 swb with 350 (supposedly) Can't really trust the previous owner I am finding out.

I am not at all mechanical and know very little about cars/trucks but I am learning!

I could use your help identifying which transfer case and transmission I have. I took a few photos that I hope help.

I'm also worried about the putty on the end of transfer case going to drive shaft. Why is there putty there/should I be concerned? I could see fluid dripping from it after use.

On the orange cover it says CFD 207. Near it it has 140373 77
The 77 has larger numbers than the rest.

The other letters I see shown in photos are AE followed by 6 numbers I can't see.

Thank you!!!
