Well guys, i'm back, with more problems (well actually the same one). You may remember this thread from a while back:
http://www.jeepforum.com/forum/f13/leak-where-transmission-meets-transfer-case-976549/
The leak mentioned in that thread is still going on, and has not been fixed yet. I suppose I will just take it from the top.
3-4 months ago I killed my NP249 t-case, came grinding to a stop, only ran in 4 low. So I though, the only logical solution is to swap the t-case for an np242 t-case, and just swap the input shafts.
So, I did that I took my 249 out, pulled out the input shaft, and had it swapped into the NP242 at a shop. I put the 242 in myself, and didn't do the seals at that time. I took it for a test drive, and found that I had a really bad leak. So, thats when I posted that thread. I pulled the t-case out after that, and did the seals, once I put it back together it still leaked, just as bad as before.
So, I said screw it, and took it to a transmission shop, they told me that my motor mounts were bad, shaking the trans, causing the seal to break. Sounds reasonable, right? So, they did the motor mounts, and seals again. Still leaks.
That brings us up to last week, they took the t-case out again, did the seals a third time, split the case, and resealed basically everything. It still leaks, just as bad.
We did find out that the leak is not coming from the t-case, it is coming from the transmission. So their theory is that the input shaft is too short and not reaching the transmission seal. Keep in mind that the input shaft in the np242 is the one that came from my old np249. They told me that those were just not compatible for some reason. I have no idea.
I'm sure that was terribly confusing but, I really seriously need some help, advice, ideas, anything with this thing. I am so burned out with this jeep, I'm about to just buy a 249, throw it in, and sell it.
So, any other ideas on what might be causing this leak, or how I could fix it without putting in another 249?
