Hello,
I am neck deep in replacing the transfer case (4405) in my 1999 explorer and ran into something I hope I can get some help with. I was at the point where I was splitting the transfer case from the transmission and once I got the seam open, about a quart of transmission fluid drained from the cavity between the both cases. I could be wrong, but I thought this was supposed to be a dry area???? There is a gasket between the two surfaces but my first thought was a bad transmission output shaft seal or is this normal? Again, I was not even close to the point where the transmission output shaft itself was free of the transfer case, just a small crack between the two and pow, transmission fluid shower. It made me wonder if it was possible that AFT had contaminated the transfer case and caused the failure. The Explorer has 175k miles with no transmission work ever done to it so a bad output shaft seal would not be much of a surprise.
Any insight would be much appreciated.
Thanks!!!!
