On my two 88 GL's I run Redline MT 90 in the transmissions. Not sure off
the top what grade oil that is    - unless the 90 means 90 wt.

Re-facing the fly wheel depends on how bad the surface  is and whether
it got a new clutch or not. With a new pressure plate and clutch disk
having the flywheel resurfaced and trued up is definitely in order. Two
things to consider - 1) be careful of your shims. Resurfacing may
require some adjustment. of them. and 2) there is a little bushing that
fits into the center bore of the flywheel. That little shim holds the
felt seal over the bearing that fits intot he end of the crankshaft.
Don't lose it. Don't let it got to the shop when sending the flywheel
out. Machinests knock it out when mountinge the flywheel and it never
gets put back in. It is there for a reason. And these are NLA!! If this
is not present - the bearings die early.

I think replacing the flywheel seal when the tranny is removed is a good
idea. Just my opinion. Saves a lot of lost motion and angst if you find
yourself with a leaking seal later. If you go ahead and doing it while
all is apart - you may never have a leaking seal for a very long time to
come.

My $0.02.
