1995 Toyota 4Runner leaking at transfer case adapter

Hey guys, I currently have a leak at the transmission and transfer case sides of my transfer case adapter. Bought the vehicle a year ago and now it seems to just be leaking profusively from the front and rear of the adapter. Even when cold and not running. I had also noticed that all my transfer case seals are RTV And Iím unsure if that is normal from the factory or if somebody had previously been in the transfer case. Before I go and pull the transfer case and put gaskets in place of RTV on my t case adapter, is there any other reason my tcase adapter could be leaking from both ends? Thanks in advance!

What he said^ also your asking 3rd Gen 4Runners 96-02, although very similar. But also What is losing fluid, the T-case or the transmission, manual or Auto, yes it is normal to see sealant on the T-case halves if that is what you mean, and I do use RTV on the outer edge of the seal if thats what you mean, there is no gasket AFAIK, must be a leak on the seal for the input of the t-case or output on the transmission if it is coming from that location.

moving to correct section

sounds like you probably have a 5 speed R150 trans, the chain drive case on these things like to leak.
If I am wrong and you have the A340 auto with the integrated transfer case you could be in for some major work

RTV is not normal, sounds like a previous owner may have band aided a quick fix. that being said RTV used correctly can and will work as a good sealant when done properly..hopefully they didn't try to RTV the output seals

Just be sure fluid is not being pushed out the top running down the sides before pulling every thing apart .

Then without dropping both the case and the transmission and installing them as a unit .

The rear Transmission seal keeps you from getting the transfer case in
