The bushing on the shift rod can be replaced, a better way of fixing the
slop. If the ball is too worn (I doubt this), replace it.

They are filled from the same hole (in front of the trans above the front
drain plug). Do not exceed the max fluid for the trans. The procedure is to
do it in the car (to bottom of feed hole), though just level is good on the
table. Again, Bentley lists the exact amount of fluid for the trans.
Exceeding it, can cause leaking in the input shaft seal. BTW, replacing that
input shaft seal, the pilot bearing (in the crank) and the crank seal is a
good idea. Don't forget to locktite the flywheel bolts too, you can get oil
leakage around the threads. Also, Bentley has the torque specifications for
the flywheel and the PP listed backwards in the clutch section (but correctly
in the trans section). ***Don't*** put 55ft/lbs of torque on the PP allen

The difference between an unloaded open diff, and an unloaded locked diff in
terms of what happens to the shafts is the same. Did the diff lock light
come on before you took the trans out? If it did, it's most likely working.
The best test is to put 2 wheels up in the air, 2 on the ground (f/r), when
locked, the 2 fronts won't rotate without the 2 rears. I've never seen a
front diff failure in terms of the locking diff mechanism. The vacuum
actuators fail quite regularly though. Bottom Line: Really isn't a bench
test, it's an installed test.

Yes, general purpose grease (lightly) is fine. The plastic v metal release
bearings are interchangeable and really don't affect performance of the part,
IME. Also, use the package of grease that comes with the clutch kit to lube
the input shaft splines. Failure to do this can result in an expensive
That was relatively easy....
