Possible Transmission Issue

[frawstme]

do you know anything about the history of this car? was the transfer case rebuilt?

i rebuilt mine and made a mistake that lead to ATF flowing into the transfer case. it caused some major issues for me. might not be the same problem but worth considering

I don't know a lot about it, but a guy in his mid 60s inherited the car from his mom who was almost 90. He had it for a year and a half, and essentially didn't have the means to fix things that were happening. Almost positive it hasn't been touched. I will be pulling the transfer case off to put in a new output seal and probably an input seal. Unless there's a leak somewhere else that is showing itself at the output shaft.

Also, I will heed your advice and not jump into swapping a transmission. I was discouraged from dropping the pan when my friend who knows a lot about 100 series, said he wouldn’t waste time and would just swap in a used trans. Thanks for the response.

Fair enough...Your in a bit over my head for this one. I haven't really any experience diagnosing something like this . Sounds like you have already done all of the basic stuff so I'm stumped

before doing anything else
I would drain the transfer case, leave plug out
add atf to trans and see if any comes out the transfer drain
you said you drained the transfer and only got gear oil
I wouldn't waste my time fixing a small leak on the output shaft of the transfer until I figured out the trans issue
