Hi Aerocolorado:
Finally succeeded in opening that nut. It turns out that when the T/C has been removed from the van, one could remove the sensor that reads the front output shaft. Through that port, I stick a large flathead screwdriver (with several layers of duct tape around it) and bear against the gear on the rear of the output shaft. That holds it stationary and I open the nut with a 1-7/8" socket. Later on, for assembly, I plan to put on some thread locker and just use my small impact wrench. The manual calls for 165 ft-lbs and my impact wrench puts out about 175 ft-lbs. Allowing for the motion of the shaft, that would be in the ballpark - I hope
Thanks again for the offer to help. I really appreciate that.

I never received your regular email, even checked the spam filter, so I don't know where it wound up. Glad you got the private message and the offer stands. Would not be a problem. Remember to pick up a new mounting gasket for the connection between the TC and transmission. Once the TC is remounted you could re-connect the rear driveshaft and torque the nut down before installing the front drive shaft. Good luck!

Thanks Aeroscolorado. Anyway, I'm glad I decided to open it up since there is definitely a problem, either in the T/C or the Transmission. The area in between the two should be dry since there are seals in the transmission extension housing and on the T/C input shaft. However, I saw quite a bit of transmission fluid in there, so there must be a leak between the two of them. I'm going to change all the seals in the T/C and the rear seal on the Transmission just for good measure. The chain and bearings on the T/C appear to be in really good shape since I could not detect any play in the T/C input or output shafts, so I'm going to leave those alone. On second thought, may be I'll open up the transmission and change all the seals and the clutches too, jus so I don't have to mess with it later when it goes.
Again, thanks for the offer and if you ever need any tools to work on your tranny, let me know. I have bought some and fabricated some, just enough to rebuild all versions of the A4LD, so if you need anything, just holler.
Regards,
Tung

You're quite welcome. This sounds suspiciously familiar, small problem leads to major overhaul, but this is a fun rebuild. As to the transmission, I've been collecting various OTC essential tool kits via eBay for the past year with an eye toward having to rebuild my own. When the time comes I might have to visit with you regarding the fabricated tools.
Happy wrenching!
