Your posts will be very helpful to me and others too as Bonnevilles are traded & sold from "I'll just buy a new car" owners to "I'll pay to have someone fix it for me" to "I'll fix it myself" owners like me. Then it moves on down to high school & college kids who (1)have Dad fix it, (2) pay someone or (3) decide to learn something by fixing it themselves.

Some follow-up for the OP:
Watch for the drive / driven thrust washers (above they stuck to the inside of the case cover).
I found some scant info online:
Date: 02/01/2001
Component Name: 980000 OTHER
NHTSA #: 32
SUMMARY: INFORMATION REGARDING EXTRA CLIPS IN THE 4T65E TRANSMISSION. *SLC
And it seems it dates back all the way to 1997. Anyone able to access full text of TSB'*?
gmpartsdirect does have the pump shaft, for $31.42 (plus shipping), p/n 24209284

I believe I once saw a TSB about "extra clips" being found in 4T65E transaxles; I have to find that again :?

You may be able to get away with not pulling the diffy cover / diffy / output shaft. In my case, while I was dismantling, I tried to re-fit the 4th clutch hub shaft splines into the inside of the input sun gear splines immediately after pulling the hub out. It would not go in unless I reached in from the (already removed) diffy side and pushed upward on the input sun gear to line things up. Maybe the output shaft being in place would have prevented the input gear from going out of alignment like that, I don't know.
I'd say go ahead and try to swap in the hub without pulling the diffy stuff. If it won't seat, then pull the diffy.

Constructed an engine support using a couple of 2x4'*.
Need to remove the steering shaft link, undo the left subframe bolts, remove the tranny mount from the side cover & I'll be ready to pull the cover. ( I've also done a bunch of other required steps.)
