So I noticed a slight leak last night from the bottom of the Transfer Case could it be a gasket? How often should the fluid be changed?

2000 F150 4.6 V8 4X4

 

Look again to see if it is coming from the extension housing or the drain between the t-case and the tranny or the fill or drain plugs. The seal in the transmission has been known to leak and fill the space between the tranny and the t-case. They then leak through the drain.

EDIT Just so we are clear, the drain between the t-case and the tranny is where the transmission fluid comes out. Not the t-case drain plug or fill plug. They sometimes leag if improperly installed.

 

I too have noticed a slight transmission fluid leak coming from my truck. At first I thought it may have been leaking from the transfer case itself, but when I crawled up and looked closer it appeared to be starting from a hose that connects from the transmission to the transfer case.

I'm fairly ignorant as to how these things operate, but I didn't know if the transfer case shared fluid from the tranny. If so, I'm guessing it happens when I use the 4x4 - which I did one day last week during a heavy rain on the way home.

The truck seems to be running fine otherwise, but I didn't know what to expect as far as repair costs. Any input would be greatly appreciated.
